### Merging
When development is complete on an issue, the first step toward merging it
back into the master branch is to file a Pull Request (PR). The contributions
back into the master branch is to file a Pull Request. The contributions
should meet code, test, and commit message standards as described below,
and the pull request should include a completed author checklist, also
as described below. Pull requests may be assigned to specific team
members when appropriate (e.g. to draw to a specific person's attention).
members when appropriate (e.g. to draw to a specific person's attention.)
Code review should take place using discussion features within the pull
request. When the reviewer is satisfied, they should add a comment to
the pull request containing the reviewer checklist (from below) and complete
the merge back to the master branch.
Additionally:
* Every pull request must link to the issue that it addresses. Eg. “Addresses #1234” or “Closes #1234”. This is the responsibility of the pull requests __author__. If no issue exists, [create one](https://github.com/nasa/openmct/issues/new/choose).
* Every __author__ must include testing instructions. These instructions should identify the areas of code affected, and some minimal test steps. If addressing a bug, reproduction steps should be included, if they were not included in the original issue. If reproduction steps were included on the original issue, and are sufficient, refer to them.
* A pull request that closes an issue should say so in the description. Including the text “Closes #1234” will cause the linked issue to be automatically closed when the pull request is merged. This is the responsibility of the pull requests __author__.
* When a pull request is merged, and the corresponding issue closed, the __reviewer__ must add the tag “unverified” to the original issue. This will indicate that although the issue is closed, it has not been tested yet.
* Every PR must have two reviewers assigned, though only one approval is necessary for merge.
* Changes to API require approval by a senior developer.
* When creating a PR, it is the author's responsibility to apply any priority label from the issue to the PR as well. This helps with prioritization.
## Standards
Contributions to Open MCT are expected to meet the following standards.
Contributions to Open MCT Web are expected to meet the following standards.
In addition, reviewers should use general discretion before accepting
changes.
### Code Standards
JavaScript sources in Open MCT must satisfy the ESLint rules defined in
this repository. This is verified by the command line build.
JavaScript sources in Open MCT Web must satisfy JSLint under its default
settings. This is verified by the command line build.
#### Code Guidelines
The following guidelines are provided for anyone contributing source code to the Open MCT project:
JavaScript sources in Open MCT Web should:
1. Write clean code. Heres a good summary - https://github.com/ryanmcdermott/clean-code-javascript.
1. Include JSDoc for any exposed API (e.g. public methods, classes).
1. Include non-JSDoc comments as-needed for explaining private variables,
methods, or algorithms when they are non-obvious. Otherwise code
should be self-documenting.
1. Classes and Vue components should use camel case, first letter capitalized
(e.g. SomeClassName).
1. Methods, variables, fields, events, and function names should use camelCase,
first letter lower-case (e.g. someVariableName).
1. Source files that export functions should use camelCase, first letter lower-case (eg. testTools.js)
1. Constants (variables or fields which are meant to be declared and
initialized statically, and never changed) should use only capital
letters, with underscores between words (e.g. SOME_CONSTANT). They should always be declared as `const`s
1. File names should be the name of the exported class, plus a .js extension
(e.g. SomeClassName.js).
1. Avoid anonymous functions, except when functions are short (one or two lines)
and their inclusion makes sense within the flow of the code
(e.g. as arguments to a forEach call). Anonymous functions should always be arrow functions.
1. Named functions are preferred over functions assigned to variables.
eg.
```JavaScript
function renameObject(object, newName) {
Object.name = newName;
}
```
is preferable to
```JavaScript
const rename = (object, newName) => {
Object.name = newName;
}
```
1. Avoid deep nesting (especially of functions), except where necessary
(e.g. due to closure scope).
1. End with a single new-line character.
1. Always use ES6 `Class`es and inheritence rather than the pre-ES6 prototypal
pattern.
1. Within a given function's scope, do not mix declarations and imperative
code, and present these in the following order:
* First, variable declarations and initialization.
* Secondly, imperative statements.
* Finally, the returned value. A single return statement at the end of the function should be used, except where an early return would improve code clarity.
1. Avoid the use of "magic" values.
eg.
```JavaScript
const UNAUTHORIZED = 401;
if (responseCode === UNAUTHORIZED)
```
is preferable to
```JavaScript
if (responseCode === 401)
```
1. Use the ternary operator only for simple cases such as variable assignment. Nested ternaries should be avoided in all cases.
1. Test specs should reside alongside the source code they test, not in a separate directory.
1. Organize code by feature, not by type.
eg.
```
- telemetryTable
- row
TableRow.js
TableRowCollection.js
TableRow.vue
- column
TableColumn.js
TableColumn.vue
plugin.js
pluginSpec.js
```
is preferable to
```
- telemetryTable
- components
TableRow.vue
TableColumn.vue
- collections
TableRowCollection.js
TableColumn.js
TableRow.js
plugin.js
pluginSpec.js
```
Deviations from Open MCT code style guidelines require two-party agreement,
* Use four spaces for indentation. Tabs should not be used.
* Include JSDoc for any exposed API (e.g. public methods, constructors.)
* Include non-JSDoc comments as-needed for explaining private variables,
methods, or algorithms when they are non-obvious.
* Define one public class per script, expressed as a constructor function
returned from an AMD-style module.
* Follow “Java-like” naming conventions. These includes:
* Classes should use camel case, first letter capitalized
(e.g. SomeClassName.)
* Methods, variables, fields, and function names should use camel case,
first letter lower-case (e.g. someVariableName.) Constants
(variables or fields which are meant to be declared and initialized
statically, and never changed) should use only capital letters, with
underscores between words (e.g. SOME_CONSTANT.)
* File name should be the name of the exported class, plus a .js extension
(e.g. SomeClassName.js)
* Avoid anonymous functions, except when functions are short (a few lines)
and/or their inclusion makes sense within the flow of the code
(e.g. as arguments to a forEach call.)
* Avoid deep nesting (especially of functions), except where necessary
(e.g. due to closure scope.)
* End with a single new-line character.
* Expose public methods by declaring them on the class's prototype.
* Within a given function's scope, do not mix declarations and imperative
code, and present these in the following order:
* First, variable declarations and initialization.
* Second, function declarations.
* Third, imperative statements.
* Finally, the returned value.
Deviations from Open MCT Web code style guidelines require two-party agreement,
typically from the author of the change and its reviewer.
#### Code Example
```js
/*global define*/
/**
* Bundles should declare themselves as namespaces in whichever source
* file is most like the "main point of entry" to the bundle.
* @namespace some/bundle
*/
define(
['./OtherClass'],
function (OtherClass) {
"use strict";
/**
* A summary of how to use this class goes here.
*
* @constructor
* @memberof some/bundle
*/
function ExampleClass() {
}
// Methods which are not intended for external use should
// not have JSDoc (or should be marked @private)
ExampleClass.prototype.privateMethod = function () {
};
/**
* A summary of this method goes here.
* @param {number} n a parameter
* @returns {number} a return value
*/
ExampleClass.prototype.publicMethod = function (n) {
return n * 2;
}
return ExampleClass;
}
);
```
### Test Standards
Automated testing shall occur whenever changes are merged into the main
development branch and must be confirmed alongside any pull request.
Automated tests are tests which exercise plugins, API, and utility classes.
Tests are subject to code review along with the actual implementation, to
ensure that tests are applicable and useful.
Automated tests are typically unit tests which exercise individual software

@ -239,26 +222,8 @@ Examples of useful tests:
* Tests which verify expected interactions with other components in the
system.
#### Guidelines
* 100% statement coverage is achievable and desirable.
* Do blackbox testing. Test external behaviors, not internal details. Write tests that describe what your plugin is supposed to do. How it does this doesn't matter, so don't test it.
* Unit test specs for plugins should be defined at the plugin level. Start with one test spec per plugin named pluginSpec.js, and as this test spec grows too big, break it up into multiple test specs that logically group related tests.
* Unit tests for API or for utility functions and classes may be defined at a per-source file level.
* Wherever possible only use and mock public API, builtin functions, and UI in your test specs. Do not directly invoke any private functions. ie. only call or mock functions and objects exposed by openmct.* (eg. openmct.telemetry, openmct.objectView, etc.), and builtin browser functions (fetch, requestAnimationFrame, setTimeout, etc.).
* Where builtin functions have been mocked, be sure to clear them between tests.
* Test at an appropriate level of isolation. Eg.
* If youre testing a view, you do not need to test the whole application UI, you can just fetch the view provider using the public API and render the view into an element that you have created.
* You do not need to test that the view switcher works, there should be separate tests for that.
* You do not need to test that telemetry providers work, you can mock openmct.telemetry.request() to feed test data to the view.
* Use your best judgement when deciding on appropriate scope.
* Automated tests for plugins should start by actually installing the plugin being tested, and then test that installing the plugin adds the desired features and behavior to Open MCT, observing the above rules.
* All variables used in a test spec, including any instances of the Open MCT API should be declared inside of an appropriate block scope (not at the root level of the source file), and should be initialized in the relevant beforeEach block. `beforeEach` is preferable to `beforeAll` to avoid leaking of state between tests.
* A `afterEach` or `afterAll` should be used to do any clean up necessary to prevent leakage of state between test specs. This can happen when functions on `window` are wrapped, or when the URL is changed. [A convenience function](https://github.com/nasa/openmct/blob/master/src/utils/testing.js#L59) is provided for resetting the URL and clearing builtin spies between tests.
* If writing unit tests for legacy Angular code be sure to follow [best practices in order to avoid memory leaks](https://www.thecodecampus.de/blog/avoid-memory-leaks-angularjs-unit-tests/).
#### Examples
* [Example of an automated test spec for an object view plugin](https://github.com/nasa/openmct/blob/master/src/plugins/telemetryTable/pluginSpec.js)
* [Example of an automated test spec for API](https://github.com/nasa/openmct/blob/master/src/api/time/TimeAPISpec.js)
During automated testing, code coverage metrics will be reported. Line
coverage must remain at or above 80%.
### Commit Message Standards

Issues are tracked at https://github.com/nasa/openmctweb/issues
Issues should include:
* A short description of the issue encountered.
* A longer-form description of the issue encountered. When possible, steps to
reproduce the issue.
* When possible, a description of the impact of the issue. What use case does
it impede?
* An assessment of the severity of the issue.
Issue severity is categorized as follows (in ascending order):
* _Trivial_: Minimal impact on the usefulness and functionality of the software; a "nice-to-have." Visual impact without functional impact,
* _Medium_: Some impairment of use, but simple workarounds exist
* _Critical_: Significant loss of functionality or impairment of use. Display of telemetry data is not affected though.
* _Blocker_: Major functionality is impaired or lost, threatening mission success. Display of telemetry data is impaired or blocked by the bug, which could lead to loss of situational awareness.
* _Trivial_: Minimal impact on the usefulness and functionality of the
software; a "nice-to-have."
* _(Unspecified)_: Major loss of functionality or impairment of use.
* _Critical_: Large-scale loss of functionality or impairment of use,
such that remaining utility becomes marginal.
* _Blocker_: Harmful or otherwise unacceptable behavior. Must fix.

# Open MCT Web
Open MCT (Open Mission Control Technologies) is a next-generation mission control framework for visualization of data on desktop and mobile devices. It is developed at NASA's Ames Research Center, and is being used by NASA for data analysis of spacecraft missions, as well as planning and operation of experimental rover systems. As a generalizable and open source framework, Open MCT could be used as the basis for building applications for planning, operation, and analysis of any systems producing telemetry data.
Open MCT Web is a web-based platform for mission operations user interface
software.
Please visit our [Official Site](https://nasa.github.io/openmct/) and [Getting Started Guide](https://nasa.github.io/openmct/getting-started/)
## Bundles
Once you've created something amazing with Open MCT, showcase your work in our GitHub Discussions [Show and Tell](https://github.com/nasa/openmct/discussions/categories/show-and-tell) section. We love seeing unique and wonderful implementations of Open MCT!
A bundle is a group of software components (including source code, declared
as AMD modules, as well as resources such as images and HTML templates)
that are intended to be added or removed as a single unit. A plug-in for
Open MCT Web will be expressed as a bundle; platform components are also
expressed as bundles.
## See Open MCT in Action
A bundle is also just a directory which contains a file `bundle.json`,
which declares its contents.
Try Open MCT now with our [live demo](https://openmct-demo.herokuapp.com/).
![Demo](https://nasa.github.io/openmct/static/res/images/Open-MCT.Browse.Layout.Mars-Weather-1.jpg)
## Open MCT v2.0.0
Support for our legacy bundle-based API, and the libraries that it was built on (like Angular 1.x), have now been removed entirely from this repository.
For now if you have an Open MCT application that makes use of the legacy API, [a plugin](https://github.com/nasa/openmct-legacy-plugin) is provided that bootstraps the legacy bundling mechanism and API. This plugin will not be maintained over the long term however, and the legacy support plugin will not be tested for compatibility with future versions of Open MCT. It is provided for convenience only.
### How do I know if I am using legacy API?
You might still be using legacy API if your source code
* Contains files named bundle.js, or bundle.json,
* Makes calls to `openmct.$injector()`, or `openmct.$angular`,
* Makes calls to `openmct.legacyRegistry`, `openmct.legacyExtension`, or `openmct.legacyBundle`.
### What should I do if I am using legacy API?
Please refer to [the modern Open MCT API](https://nasa.github.io/openmct/documentation/). Post any questions to the [Discussions section](https://github.com/nasa/openmct/discussions) of the Open MCT GitHub repository.
## Building and Running Open MCT Locally
Building and running Open MCT in your local dev environment is very easy. Be sure you have [Git](https://git-scm.com/downloads) and [Node.js](https://nodejs.org/) installed, then follow the directions below. Need additional information? Check out the [Getting Started](https://nasa.github.io/openmct/getting-started/) page on our website.
(These instructions assume you are installing as a non-root user; developers have [reported issues](https://github.com/nasa/openmct/issues/1151) running these steps with root privileges.)
1. Clone the source code
`git clone https://github.com/nasa/openmct.git`
2. Install development dependencies. Note: Check the package.json engine for our tested and supported node versions.
`npm install`
3. Run a local development server
`npm start`
Open MCT is now running, and can be accessed by pointing a web browser at [http://localhost:8080/](http://localhost:8080/)
## Documentation
Documentation is available on the [Open MCT website](https://nasa.github.io/openmct/documentation/).
### Examples
The clearest examples for developing Open MCT plugins are in the
[tutorials](https://github.com/nasa/openmct-tutorial) provided in
our documentation.
We want Open MCT to be as easy to use, install, run, and develop for as
possible, and your feedback will help us get there! Feedback can be provided via [GitHub issues](https://github.com/nasa/openmct/issues/new/choose), [Starting a GitHub Discussion](https://github.com/nasa/openmct/discussions), or by emailing us at [arc-dl-openmct@mail.nasa.gov](mailto:arc-dl-openmct@mail.nasa.gov).
## Building Applications With Open MCT
Open MCT is built using [`npm`](http://npmjs.com/) and [`webpack`](https://webpack.js.org/).
See our documentation for a guide on [building Applications with Open MCT](https://github.com/nasa/openmct/blob/master/API.md#starting-an-open-mct-application).
## Compatibility
This is a fast moving project and we do our best to test and support the widest possible range of browsers, operating systems, and nodejs APIs. We have a published list of support available in our package.json's `browserslist` key.
If you encounter an issue with a particular browser, OS, or nodejs API, please file a [GitHub issue](https://github.com/nasa/openmct/issues/new/choose)
## Plugins
Open MCT can be extended via plugins that make calls to the Open MCT API. A plugin is a group
of software components (including source code and resources such as images and HTML templates)
that is intended to be added or removed as a single unit.
As well as providing an extension mechanism, most of the core Open MCT codebase is also
written as plugins.
For information on writing plugins, please see [our API documentation](https://github.com/nasa/openmct/blob/master/API.md#plugins).
The file `bundles.json` (note the plural), at the top level of the
repository, is a JSON file containing an array of all bundles (expressed as
directory names) to include in a running instance of Open MCT Web. Adding or
removing paths from this list will add or remove bundles from the running
application.
## Tests
Tests are written for [Jasmine 3](https://jasmine.github.io/api/3.1/global)
Tests are written for [Jasmine 1.3](http://jasmine.github.io/1.3/introduction.html)
and run by [Karma](http://karma-runner.github.io). To run:
`npm test`

### Test Reporting
When `npm test` is run, test results will be written as HTML to
`dist/reports/tests/`. Code coverage information is written to `dist/reports/coverage`.
`target/tests`. Code coverage information is written to `target/coverage`.
Code Coverage Reports are available from [codecov.io](https://app.codecov.io/gh/nasa/openmct/)
### Functional Testing
The tests described above are all at the unit-level; an additional
test suite using [Protractor](https://angular.github.io/protractor/)
is under development, in the `protractor` folder.
To run:
* Install protractor following the instructions above.
* `cd protractor`
* `npm install`
* `npm run all`
## Build
Open MCT Web is built using [`npm`](http://npmjs.com/)
and [`gulp`](http://gulpjs.com/).
To build:
`npm run prepublish`
This will compile and minify JavaScript sources, as well as copy over assets.
The contents of the `dist` folder will contain a runnable Open MCT Web
instance (e.g. by starting an HTTP server in that directory), including:
* A `main.js` file containing Open MCT Web source code.
* Various assets in the `example` and `platform` directories.
* An `index.html` that runs Open MCT Web in its default configuration.
Additional `gulp` tasks are defined in [the gulpfile](gulpfile.js).
### Building Documentation
Open MCT Web's documentation is generated by an
[npm](https://www.npmjs.com/)-based build. It has additional dependencies that
may not be available on every platform and thus is not covered in the standard
npm install. Ensure your system has [libcairo](http://cairographics.org/)
installed and then run the following commands:
* `npm install`
* `npm install canvas nomnoml`
* `npm run docs`
Documentation will be generated in `target/docs`.

# Composition API - Overview
The composition API is straightforward:
MCT.composition(object) -- returns a `CompositionCollection` if the object has
composition, returns undefined if it doesn't.
## CompositionCollection
Has three events:
* `load`: when the collection has completed loading.
* `add`: when a new object has been added to the collection.
* `remove` when an object has been removed from the collection.
Has three methods:
`Collection.load()` -- returns a promise that is fulfilled when the composition
has loaded.
`Collection.add(object)` -- add a domain object to the composition.
`Collection.remove(object)` -- remove the object from the composition.
## Composition providers
composition providers are anything that meets the following interface:
* `provider.appliesTo(domainObject)` -> return true if this provider can provide
composition for a given domain object.
* `provider.add(domainObject, childObject)` -> adds object
* `provider.remove(domainObject, childObject)` -> immediately removes objects
* `provider.load(domainObject)` -> returns promise for array of children
There is a default composition provider which handles loading composition for
any object with a `composition` property. If you want specialized composition
loading behavior, implement your own composition provider and register it with
`MCT.composition.addProvider(myProvider)`

# Object API - Overview
The object API provides methods for fetching domain objects.
# Keys
Keys are a composite identifier that is used to create and persist objects. Ex:
```javascript
{
namespace: 'elastic',
identifier: 'myIdentifier'
}
```
In old MCT days, we called this an "id", and we encoded it in a single string.
The above key would encode into the identifier, `elastic:myIdentifier`.
When interacting with the API you will be dealing with key objects.
# Configuring the Object API
The following methods should be used before calling run. They allow you to
configure the persistence space of MCT.
* `MCT.objects.addRoot(key)` -- add a "ROOT" to Open MCT by specifying it's
key.
* `MCT.objects.removeRoot(key)` -- Remove a "ROOT" from Open MCT by key.
* `MCT.objects.addProvider(namespace, provider)` -- register an object provider
for a specific namespace. See below for documentation on the provider
interface.
# Using the object API
The object API provides methods for getting, saving, and deleting objects.
* MCT.objects.get(key) -> returns promise for an object
* MCT.objects.save(object) -> returns promise that is resolved when object
has been saved
* MCT.objects.delete(object) -> returns promise that is resolved when object has
been deleted
## Configuration Example: Adding a groot
The following example adds a new root object for groot and populates it with
some pieces of groot.
```javascript
var ROOT_KEY = {
namespace: 'groot',
identifier: 'groot'
};
var GROOT_ROOT = {
name: 'I am groot',
type: 'folder',
composition: [
{
namespace: 'groot',
identifier: 'arms'
},
{
namespace: 'groot',
identifier: 'legs'
},
{
namespace: 'groot',
identifier: 'torso'
}
]
};
var GrootProvider = {
get: function (key) {
if (key.identifier === 'groot') {
return Promise.resolve(GROOT_ROOT);
}
return Promise.resolve({
name: 'Groot\'s ' + key.identifier
});
}
};
MCT.objects.addRoot(ROOT_KEY);
MCT.objects.addProvider('groot', GrootProvider);
MCT.run();
```
### Making a custom provider:
All methods on the provider interface are optional, so you do not need
to modify them.
* `provider.get(key)` -> promise for a domain object.
* `provider.save(domainObject)` -> returns promise that is fulfilled when object
has been saved.
* `provider.delete(domainObject)` -> returns promise that is fulfilled when
object has been deleted.

# Region API - Overview
The region API provides a method for specifying which views should display in a given region for a given domain object. As such, they also define the basic view interface that components must define.
### MCT.region.Region
The base region type, all regions implement this interface.
`register(view)`
`getViews(domainObject)`
Additionally, Regions may have subregions for different modes of the application. Specifying a view for a region
### MCT.region.View
The basic type for views. You can extend this to implement your own functionality, or you can create your own object so long as it meets the interface.
`attribute` | `type` | `note`
--- | --- | ---
`label` | `string` or `Function` | The name of the view. Used in the view selector when more than one view exists for an object.
`glyph` | `string` or `Function` | The glyph to associate with this view. Used in the view selector when more than one view exists for an object.
`instantiate` | `Function` | constructor for a view. Will be invoked with two arguments, `container` and `domainObject`. It should return an object with a `destroy` method that is called when the view is removed.
`appliesTo` | `Function` | Determines if a view applies to a specific domain object. Will be invoked with a domainObject. Should return a number, `priority` if the view applies to a given object. If multiple views return a truthy value for a given object, they will be ordered by priority, and the largest priority value will be the default view for the object. Return `false` if a view should not apply to an object.
Basic Hello World:
```javascript
function HelloWorldView(container, domainObject) {
container.innerHTML = 'Hello World!';
}
HelloWorldView.label = 'Hello World';
HelloWorldView.glyph = 'whatever';
HelloWorldView.appliesTo = function (domainObject) {
return 10;
};
HelloWorldView.prototype.destroy = function () {
// clean up outstanding handlers;
};
MCT.regions.Main.register(HelloWorldView);
```
## Region Hierarchy
Regions are organized in a hierarchy, with the most specific region taking precedence over less specific regions.
If you specify a view for the Main Region, it will be used for both Edit and View modes. You can override the Main Region view for a specific mode by registering the view with that specific mode.
### MCT.regions.Tree
### MCT.regions.Main
### MCT.regions.Main.View
### MCT.regions.Main.Edit
### MCT.regions.Inspector
### MCT.regions.Inspector.View
### MCT.regions.Inspector.Edit
### MCT.regions.Toolbar
### MCT.regions.Toolbar.View

# Telemetry API - Overview
The Telemetry API provides basic methods for retrieving historical and realtime telemetry data, retrieving telemetry metadata, and registering additional telemetry providers.
The Telemetry API also provides a set of helpers built upon these basics-- TelemetryFormatters help you format telemetry values for display purposes, LimitEvaluators help you display evaluate and display alarm states, while TelemetryCollections provide a method for seamlessly combining historical and realtime data, while supporting more advanced client side filtering and interactivity.
## Getting Telemetry Data
### `MCT.telemetry.request(domainObject, options)`
Request historical telemetry for a domain object. Options allows you to specify filters (start, end, etc.), sort order, and strategies for retrieving telemetry (aggregation, latest available, etc.).
Returns a `Promise` for an array of telemetry values.
### `MCT.telemetry.subscribe(domainObject, callback, options)`
Subscribe to realtime telemetry for a specific domain object. callback will be called whenever data is received from a realtime provider. Options allows you to specify ???
## Understanding Telemetry
### `MCT.telemetry.getMetadata(domainObject)`
Retrieve telemetry metadata for a domain object. Telemetry metadata helps you understand the sort of telemetry data a domain object can provide-- for instances, the possible enumerations or states, the units, and more.
### `MCT.telemetry.Formatter`
Telemetry formatters help you format telemetry values for display. Under the covers, they use telemetry metadata to interpret your telemetry data, and then they use the format API to format that data for display.
### `MCT.telemetry.LimitEvaluator`
Limit Evaluators help you evaluate limit and alarm status of individual telemetry datums for display purposes without having to interact directly with the Limit API.
## Adding new telemetry sources
### `MCT.telemetry.registerProvider(telemetryProvider)`
Register a telemetry provider with the telemetry service. This allows you to connect alternative telemetry sources to For more information, see the `MCT.telemetry.BaseProvider`
### `MCT.telemetry.BaseProvider`
The base provider is a great starting point for developers who would like to implement their own telemetry provider. At the same time, you can implement your own telemetry provider as long as it meets the TelemetryProvider (see other docs).
## Other tools
### `MCT.telemetry.TelemetryCollection`
The TelemetryCollection is a useful tool for building advanced displays. It helps you seamlessly handle both historical and realtime telemetry data, while making it easier to deal with large data sets and interactive displays that need to frequently requery data.
# API Reference (TODO)
* Telemetry Metadata
* Request Options
-- start
-- end
-- sort
-- ???
-- strategies -- specify which strategies you want. an array provides for fallback strategies without needing decoration. Design fallbacks into API.
### `MCT.telemetry.request(domainObject, options)`
### `MCT.telemetry.subscribe(domainObject, callback, options)`

# Type API - Overview
The Type API allows you to register type information for domain objects, and allows you to retrieve type information about a given domain object. Crucially, type information allows you to add new creatible object types.
### MCT.types.Type
The basic interface for a type. You can extend this to implement your own type,
or you can provide an object that implements the same interface.
`attribute` | `type` | `note`
--- | --- | ---
`label` | `String` | The human readible name of the type.
`key` | `String` | The unique identifier for this type.
`glyph` | `String` | The glyph identifier for the type. Displayed in trees, labels, and other locations.
`description` | `String` | A basic description of the type visible in the create menu.
`isCreatible` | `Boolean`, `Number`, or `Function` | If truthy, this type will be visible in the create menu. Note that objects not in the create menu can be instantiated via other means.
`namespace` | `String` | The object namespace that provides instances of this type. This allows you to implement custom object providers for specific types while still utilizing other namespaces for persistence.
`properties` | `Object` | Object defining properties of an instance of this class. Properties are used for automatic form generation and automated metadata display. For more information on the definition of this object, look at (some resource-- jsonschema?)
`canContain` | `Function` | determins whether objects of this type can contain other objects. Will be invoked with a domain object. Return true to allow composition, return false to disallow composition.
### MCT.types.register(type)
Register a type with the type API. Registering a type with the same key as another type will replace the original type definition.
### MCT.types.getType(typeKey)
Returns the type definition for a given typeKey. returns undefined if type does not exist.
### MCT.types.getType(domainObject)
Return the type definition for a given domain object.

# Overview
The framework layer's most basic responsibility is allowing individual
software components to communicate. The software components it recognizes
are:
* _Extensions_: Individual units of functionality that can be added to
or removed from Open MCT Web. _Extension categories_ distinguish what
type of functionality is being added/removed.
* _Bundles_: A grouping of related extensions
(named after an analogous concept from [OSGi](http://www.osgi.org/))
that may be added or removed as a group.
The framework layer operates by taking a set of active bundles, and
exposing extensions to one another as-needed, using
[dependency injection](https://en.wikipedia.org/wiki/Dependency_injection).
Extensions are responsible for declaring their dependencies in a
manner which the framework layer can understand.
```nomnoml
#direction: down
[Open MCT Web|
[Dependency injection framework]-->[Platform bundle #1]
[Dependency injection framework]-->[Platform bundle #2]
[Dependency injection framework]-->[Plugin bundle #1]
[Dependency injection framework]-->[Plugin bundle #2]
[Platform bundle #1|[Extensions]]
[Platform bundle #2|[Extensions]]
[Plugin bundle #1|[Extensions]]
[Plugin bundle #2|[Extensions]]
[Platform bundle #1]<->[Platform bundle #2]
[Plugin bundle #1]<->[Platform bundle #2]
[Plugin bundle #1]<->[Plugin bundle #2]
]
```
The "dependency injection framework" in this case is
[AngularJS](https://angularjs.org/). Open MCT Web's framework layer
is really just a thin wrapper over Angular that recognizes the
concepts of bundles and extensions (as declared in JSON files) and
registering extensions with Angular. It additionally acts as a
mediator between Angular and [RequireJS](http://requirejs.org/),
which is used to load JavaScript sources which implement
extensions.
```nomnoml
[Framework layer|
[AngularJS]<-[Framework Component]
[RequireJS]<-[Framework Component]
[Framework Component]1o-*[Bundles]
]
```
It is worth noting that _no other components_ are "aware" of the
framework component directly; Angular and Require are _used by_ the
framework components, and extensions in various bundles will have
their dependencies satisfied by Angular as a consequence of registration
activities which were performed by the framework component.
## Application Initialization
The framework component initializes an Open MCT Web application following
a simple sequence of steps.
```nomnoml
[<start> Start]->[<state> Load bundles.json]
[Load bundles.json]->[<state> Load bundle.json files]
[Load bundle.json files]->[<state> Resolve implementations]
[Resolve implementations]->[<state> Register with Angular]
[Register with Angular]->[<state> Bootstrap application]
[Bootstrap application]->[<end> End]
```
1. __Loading bundles.json.__ A file named `bundles.json` is loaded to determine
which bundles to load. Bundles are given in this file as relative paths
which point to bundle directories.
2. __Load bundle.json files.__ Individual bundle definitions are loaded; a
`bundle.json` file is expected in each bundle directory.
2. __Resolving implementations.__ Any scripts which provide implementations for
extensions exposed by bundles are loaded, using RequireJS.
3. __Register with Angular.__ Resolved extensions are registered with Angular,
such that they can be used by the application at run-time. This stage
includes both registration of Angular built-ins (directives, controllers,
routes, constants, and services) as well as registration of non-Angular
extensions.
4. __Bootstrap application.__ Once all extensions have been registered,
the Angular application
[is bootstrapped](https://docs.angularjs.org/guide/bootstrap).
## Architectural Paradigm
```nomnoml
[Extension]
[Extension]o->[Dependency #1]
[Extension]o->[Dependency #2]
[Extension]o->[Dependency #3]
```
Open MCT Web's architecture relies on a simple premise: Individual units
(extensions) only have access to the dependencies they declare that they
need, and they acquire references to these dependencies via dependency
injection. This has several desirable traits:
* Programming to an interface is enforced. Any given dependency can be
swapped out for something which exposes an equivalent interface. This
improves flexibility against refactoring, simplifies testing, and
provides a common mechanism for extension and reconfiguration.
* The dependencies of a unit must be explicitly defined. This means that
it can be easily determined what a given unit's role is within the
larger system, in terms of what other components it will interact with.
It also helps to enforce good separation of concerns: When a set of
declared dependencies becomes long it is obvious, and this is usually
a sign that a given unit is involved in too many concerns and should
be refactored into smaller pieces.
* Individual units do not need to be aware of the framework; they need
only be aware of the interfaces to the components they specifically
use. This avoids introducing a ubiquitous dependency upon the framework
layer itself; it is plausible to modify or replace the framework
without making changes to individual software components which run upon
the framework.
A drawback to this approach is that it makes it difficult to define
"the architecture" of Open MCT Web, in terms of describing the specific
units that interact at run-time. The run-time architecture is determined
by the framework as the consequence of wiring together dependencies.
As such, the specific architecture of any given application built on
Open MCT Web can look very different.
Keeping that in mind, there are a few useful patterns supported by the
framework that are useful to keep in mind.
The specific service infrastructure provided by the platform is described
in the [Platform Architecture](Platform.md).
## Extension Categories
One of the capabilities that the framework component layers on top of
AngularJS is support for many-to-one dependencies. That is, a specific
extension may declare a dependency to _all extensions of a specific
category_, instead of being limited to declaring specific dependencies.
```nomnoml
#direction: right
[Specific Extension] 1 o-> * [Extension of Some Category]
```
This is useful for introducing specific extension points to an application.
Some unit of software will depend upon all extensions of a given category
and integrate their behavior into the system in some fashion; plugin authors
can then add new extensions of that category to augment existing behaviors.
Some developers may be familiar with the use of registries to achieve
similar characteristics. This approach is similar, except that the registry
is effectively implicit whenever a new extension category is used or
depended-upon. This has some advantages over a more straightforward
registry-based approach:
* These many-to-one relationships are expressed as dependencies; an
extension category is registered as having dependencies on all individual
extensions of this category. This avoids ordering issues that may occur
with more conventional registries, which may be observed before all
dependencies are resolved.
* The need for service registries of specific types is removed, reducing
the number of interfaces to manage within the system. Groups of
extensions are provided as arrays.
## Composite Services
Composite services (registered via extension category `components`) are
a pattern supported by the framework. These allow service instances to
be built from multiple components at run-time; support for this pattern
allows additional bundles to introduce or modify behavior associated
with these services without modifying or replacing original service
instances.
```nomnoml
#direction: down
[<abstract> FooService]
[FooDecorator #1]--:>[FooService]
[FooDecorator #n]--:>[FooService]
[FooAggregator]--:>[FooService]
[FooProvider #1]--:>[FooService]
[FooProvider #n]--:>[FooService]
[FooDecorator #1]o->[<state> ...decorators...]
[...decorators...]o->[FooDecorator #n]
[FooDecorator #n]o->[FooAggregator]
[FooAggregator]o->[FooProvider #1]
[FooAggregator]o->[<state> ...providers...]
[FooAggregator]o->[FooProvider #n]
[FooDecorator #1]--[<note> Exposed as fooService]
```
In this pattern, components all implement an interface which is
standardized for that service. Components additionally declare
that they belong to one of three types:
* __Providers.__ A provider actually implements the behavior
(satisfies the contract) for that kind of service. For instance,
if a service is responsible for looking up documents by an identifier,
one provider may do so by querying a database, while another may
do so by reading a static JSON document. From the outside, either
provider would look the same (they expose the same interface) and
they could be swapped out easily.
* __Aggregator.__ An aggregator takes many providers and makes them
behave as one. Again, this implements the same interface as an
individual provider, so users of the service do not need to be
concerned about the difference between consulting many providers
and consulting one. Continuing with the example of a service that
looks up documents by identifiers, an aggregator here might consult
all providers, and return any document is found (perhaps picking one
over the other or merging documents if there are multiple matches.)
* __Decorators.__ A decorator exposes the same interface as other
components, but instead of fully implementing the behavior associated
with that kind of service, it only acts as an intermediary, delegating
the actual behavior to a different component. Decorators may transform
inputs or outputs, or initiate some side effects associated with a
service. This is useful if certain common behavior associated with a
service (caching, for instance) may be useful across many different
implementations of that same service.
The framework will register extensions in this category such that an
aggregator will depend on all of its providers, and decorators will
depend upon on one another in a chain. The result of this compositing step
(the last decorator, if any; otherwise the aggregator, if any;
otherwise a single provider) will be exposed as a single service that
other extensions can acquire through dependency injection. Because all
components of the same type of service expose the same interface, users
of that service do not need to be aware that they are talking to an
aggregator or a provider, for instance.

# Introduction
The purpose of this document is to familiarize developers with the
overall architecture of Open MCT Web.
The target audience includes:
* _Platform maintainers_: Individuals involved in developing,
extending, and maintaing capabilities of the platform.
* _Integration developers_: Individuals tasked with integrated
Open MCT Web into a larger system, who need to understand
its inner workings sufficiently to complete this integration.
As the focus of this document is on architecture, whenever possible
implementation details (such as relevant API or JSON syntax) have been
omitted. These details may be found in the developer guide.
# Overview
Open MCT Web is client software: It runs in a web browser and
provides a user interface, while communicating with various
server-side resources through browser APIs.
```nomnoml
#direction: right
[Client|[Browser|[Open MCT Web]->[Browser APIs]]]
[Server|[Web services]]
[Client]<->[Server]
```
While Open MCT Web can be configured to run as a standalone client,
this is rarely very useful. Instead, it is intended to be used as a
display and interaction layer for information obtained from a
variety of back-end services. Doing so requires authoring or utilizing
adapter plugins which allow Open MCT Web to interact with these services.
Typically, the pattern here is to provide a known interface that
Open MCT Web can utilize, and implement it such that it interacts with
whatever back-end provides the relevant information.
Examples of back-ends that can be utilized in this fashion include
databases for the persistence of user-created objects, or sources of
telemetry data.
## Software Architecture
The simplest overview of Open MCT Web is to look at it as a "layered"
architecture, where each layer more clearly specifies the behavior
of the software.
```nomnoml
#direction: down
[Open MCT Web|
[Platform]<->[Application]
[Framework]->[Application]
[Framework]->[Platform]
]
```
These layers are:
* [_Framework_](framework.md): The framework layer is responsible for
managing the interactions between application components. It has no
application-specific knowledge; at this layer, we have only
established an abstraction by which different software components
may communicate and/or interact.
* [_Platform_](platform.md): The platform layer defines the general look,
feel, and behavior of Open MCT Web. This includes user-facing components like
Browse mode and Edit mode, as well as underlying elements of the
information model and the general service infrastructure.
* _Application_: The application layer defines specific features of
an application built on Open MCT Web. This includes adapters to
specific back-ends, new types of things for users to create, and
new ways of visualizing objects within the system. This layer
typically consists of a mix of custom plug-ins to Open MCT Web,
as well as optional features (such as Plot view) included alongside
the platform.

# Overview
The Open MCT Web platform utilizes the [framework layer](Framework.md)
to provide an extensible baseline for applications which includes:
* A common user interface (and user interface paradigm) for dealing with
domain objects of various sorts.
* A variety of extension points for introducing new functionality
of various kinds within the context of the common user interface.
* A service infrastructure to support building additional components.
## Platform Architecture
While the framework provides a more general architectural paradigm for
building application, the platform adds more specificity by defining
additional extension types and allowing for integration with back end
components.
The run-time architecture of an Open MCT Web application can be categorized
into certain high-level tiers:
```nomnoml
[DOM]->[<state> AngularJS]
[AngularJS]->[Presentation Layer]
[Presentation Layer]->[Information Model]
[Presentation Layer]->[Service Infrastructure]
[Information Model]->[Service Infrastructure]
[Service Infrastructure]->[<state> Browser APIs]
[Browser APIs]->[Back-end]
```
Applications built using Open MCT Web may add or configure functionality
in __any of these tiers__.
* _DOM_: The rendered HTML document, composed from HTML templates which
have been processed by AngularJS and will be updated by AngularJS
to reflect changes from the presentation layer. User interactions
are initiated from here and invoke behavior in the presentation layer. HTML 
templates are written in Angulars template syntax; see the [Angular documentation on templates](https://docs.angularjs.org/guide/templates). 
These describe the page as actually seen by the user. Conceptually, 
stylesheets (controlling the look­and­feel of the rendered templates) belong 
in this grouping as well. 
* [_Presentation layer_](#presentation-layer): The presentation layer
is responsible for updating (and providing information to update)
the displayed state of the application. The presentation layer consists
primarily of _controllers_ and _directives_. The presentation layer is
concerned with inspecting the information model and preparing it for
display.
* [_Information model_](#information-model): Provides a common (within Open MCT 
Web) set of interfaces for dealing with “things” ­ domain objects ­ within the 
system. User­facing concerns in a Open MCT Web application are expressed as 
domain objects; examples include folders (used to organize other domain 
objects), layouts (used to build displays), or telemetry points (used as 
handles for streams of remote measurements.) These domain objects expose a 
common set of interfaces to allow reusable user interfaces to be built in the 
presentation and template tiers; the specifics of these behaviors are then 
mapped to interactions with underlying services. 
* [_Service infrastructure_](#service-infrastructure): The service
infrastructure is responsible for providing the underlying general
functionality needed to support the information model. This includes
exposing underlying sets of extensions and mediating with the
back-end.
* _Back-end_: The back-end is out of the scope of Open MCT Web, except
for the interfaces which are utilized by adapters participating in the
service infrastructure. Includes the underlying persistence stores, telemetry 
streams, and so forth which the Open MCT Web client is being used to interact 
with.
## Application Start-up
Once the
[application has been initialized](Framework.md#application-initialization)
Open MCT Web primarily operates in an event-driven paradigm; various
events (mouse clicks, timers firing, receiving responses to XHRs) trigger
the invocation of functions, typically in the presentation layer for
user actions or in the service infrastructure for server responses.
The "main point of entry" into an initialized Open MCT Web application
is effectively the
[route](https://docs.angularjs.org/api/ngRoute/service/$route#example)
which is associated with the URL used to access Open MCT Web (or a
default route.) This route will be associated with a template which
will be displayed; this template will include references to directives
and controllers which will be interpreted by Angular and used to
initialize the state of the display in a manner which is backed by
both the information model and the service infrastructure.
```nomnoml
[<start> Start]->[<state> page load]
[page load]->[<state> route selection]
[route selection]->[<state> compile, display template]
[compile, display template]->[Template]
[Template]->[<state> use Controllers]
[Template]->[<state> use Directives]
[use Controllers]->[Controllers]
[use Directives]->[Directives]
[Controllers]->[<state> consult information model]
[consult information model]->[<state> expose data]
[expose data]->[Angular]
[Angular]->[<state> update display]
[Directives]->[<state> add event listeners]
[Directives]->[<state> update display]
[add event listeners]->[<end> End]
[update display]->[<end> End]
```
# Presentation Layer
The presentation layer of Open MCT Web is responsible for providing
information to display within templates, and for handling interactions
which are initiated from templated DOM elements. AngularJS acts as
an intermediary between the web page as the user sees it, and the
presentation layer implemented as Open MCT Web extensions.
```nomnoml
[Presentation Layer|
[Angular built-ins|
[routes]
[controllers]
[directives]
[templates]
]
[Domain object representation|
[views]
[representations]
[representers]
[gestures]
]
]
```
## Angular built-ins
Several extension categories in the presentation layer map directly
to primitives from AngularJS:
* [_Controllers_](https://docs.angularjs.org/guide/controller) provide
data to templates, and expose functionality that can be called from
templates.
* [_Directives_](https://docs.angularjs.org/guide/directive) effectively
extend HTML to provide custom behavior associated with specific
attributes and tags.
* [_Routes_](https://docs.angularjs.org/api/ngRoute/service/$route#example)
are used to associate specific URLs (including the fragment identifier)
with specific application states. (In Open MCT Web, these are used to
describe the mode of usage - e.g. browse or edit - as well as to
identify the object being used.)
* [_Templates_](https://docs.angularjs.org/guide/templates) are partial
HTML documents that will be rendered and kept up-to-date by AngularJS.
Open MCT Web introduces a custom `mct-include` directive which acts
as a wrapper around `ng-include` to allow templates to be referred
to by symbolic names.
## Domain object representation
The remaining extension categories in the presentation layer are specific
to displaying domain objects.
* _Representations_ are templates that will be used to display
domain objects in specific ways (e.g. "as a tree node.")
* _Views_ are representations which are exposed to the user as options
for displaying domain objects.
* _Representers_ are extensions which modify or augment the process
of representing domain objects generally (e.g. by attaching
gestures to them.)
* _Gestures_ provide associations between specific user actions
(expressed as DOM events) and resulting behavior upon domain objects
(typically expressed as members of the `actions` extension category)
that can be reused across domain objects. For instance, `drag` and
`drop` are both gestures associated with using drag-and-drop to
modify the composition of domain objects by interacting with their
representations.
# Information Model
```nomnoml
#direction: right
[Information Model|
[DomainObject|
getId() : string
getModel() : object
getCapability(key : string) : Capability
hasCapability(key : string) : boolean
useCapability(key : string, args...) : *
]
[DomainObject] 1 +- 1 [Model]
[DomainObject] 1 o- * [Capability]
]
```
Domain objects are the most fundamental component of Open MCT Web's
information model. A domain object is some distinct thing relevant to a
user's work flow, such as a telemetry channel, display, or similar.
Open MCT Web is a tool for viewing, browsing, manipulating, and otherwise
interacting with a graph of domain objects.
A domain object should be conceived of as the union of the following:
* _Identifier_: A machine-readable string that uniquely identifies the
domain object within this application instance.
* _Model_: The persistent state of the domain object. A domain object's
model is a JavaScript object that can be losslessly converted to JSON.
* _Capabilities_: Dynamic behavior associated with the domain object.
Capabilities are JavaScript objects which provide additional methods
for interacting with the domain objects which expose those capabilities.
Not all domain objects expose all capabilities. The interface exposed
by any given capability will depend on its type (as identified
by the `key` argument.) For instance, a `persistence` capability
has a different interface from a `telemetry` capability. Using
capabilities requires some prior knowledge of their interface.
## Capabilities and Services
```nomnoml
#direction: right
[DomainObject]o-[FooCapability]
[FooCapability]o-[FooService]
[FooService]o-[foos]
```
At run-time, the user is primarily concerned with interacting with
domain objects. These interactions are ultimately supported via back-end
services, but to allow customization per-object, these are often mediated
by capabilities.
A common pattern that emerges in the Open MCT Platform is as follows:
* A `DomainObject` has some particular behavior that will be supported
by a service.
* A `Capability` of that domain object will define that behavior,
_for that domain object_, supported by a service.
* A `Service` utilized by that capability will perform the actual behavior.
* An extension category will be utilized by that capability to determine
the set of possible behaviors.
Concrete examples of capabilities which follow this pattern
(or a subset of this pattern) include:
```nomnoml
#direction: right
[DomainObject]1 o- *[Capability]
[Capability]<:--[TypeCapability]
[Capability]<:--[ActionCapability]
[Capability]<:--[PersistenceCapability]
[Capability]<:--[TelemetryCapability]
[TypeCapability]o-[TypeService]
[TypeService]o-[types]
[ActionCapability]o-[ActionService]
[ActionService]o-[actions]
[PersistenceCapability]o-[PersistenceService]
[TelemetryCapability]o-[TelemetryService]
```
# Service Infrastructure
Most services exposed by the Open MCT Web platform follow the
[composite services](Framework.md#composite-services) to permit
a higher degree of flexibility in how a service can be modified
or customized for specific applications.
To simplify usage for plugin developers, the platform also usually
includes a provider implementation for these service type that consumes
some extension category. For instance, an `ActionService` provider is
included which depends upon extension category `actions`, and exposes
all actions declared as such to the system. As such, plugin developers
can simply implement the new actions they wish to be made available without
worrying about the details of composite services or implementing a new
`ActionService` provider; however, the ability to implement a new provider
remains useful when the expressive power of individual extensions is
insufficient.
```nomnoml
[ Service Infrastructure |
[ObjectService]->[ModelService]
[ModelService]->[PersistenceService]
[ObjectService]->[CapabilityService]
[CapabilityService]->[capabilities]
[capabilities]->[TelemetryService]
[capabilities]->[PersistenceService]
[capabilities]->[TypeService]
[capabilities]->[ActionService]
[capabilities]->[ViewService]
[PersistenceService]->[<database> Document store]
[TelemetryService]->[<database> Telemetry source]
[ActionService]->[actions]
[ActionService]->[PolicyService]
[ViewService]->[PolicyService]
[ViewService]->[views]
[PolicyService]->[policies]
[TypeService]->[types]
]
```
A short summary of the roles of these services:
* _[ObjectService](#object-service)_: Allows retrieval of domain objects by
their identifiers; in practice, often the main point of entry into the
[information model](#information-model).
* _[ModelService](#model-service)_: Provides domain object models, retrieved
by their identifier.
* _[CapabilityService](#capability-service)_: Provides capabilities, as they
apply to specific domain objects (as judged from their model.)
* _[TelemetryService](#telemetry-service)_: Provides access to historical
and real-time telemetry data.
* _[PersistenceService](#persistence-service)_: Provides the ability to
store and retrieve documents (such as domain object models.)
* _[ActionService](#action-service)_: Provides distinct user actions that
can take place within the system (typically, upon or using domain objects.)
* _[ViewService](#view-service)_: Provides views for domain objects. A view
is a user-selectable representation of a domain object (in practice, an
HTML template.)
* _[PolicyService](#policy-service)_: Handles decisions about which
behavior are allowed within certain specific contexts.
* _[TypeService](#type-service)_: Provides information to distinguish
different types of domain objects from one another within the system.
## Object Service
```nomnoml
#direction: right
[<abstract> ObjectService|
getObjects(ids : Array.<string>) : Promise.<object.<string, DomainObject>>
]
[DomainObjectProvider]--:>[ObjectService]
[DomainObjectProvider]o-[ModelService]
[DomainObjectProvider]o-[CapabilityService]
```
As domain objects are central to Open MCT Web's information model,
acquiring domain objects is equally important.
```nomnoml
#direction: right
[<start> Start]->[<state> Look up models]
[<state> Look up models]->[<state> Look up capabilities]
[<state> Look up capabilities]->[<state> Instantiate DomainObject]
[<state> Instantiate DomainObject]->[<end> End]
```
Open MCT Web includes an implementation of an `ObjectService` which
satisfies this capability by:
* Consulting the [Model Service](#model-service) to acquire domain object
models by identifier.
* Passing these models to a [Capability Service](#capability-service) to
determine which capabilities are applicable.
* Combining these results together as [DomainObject](#information-model)
instances.
## Model Service
```nomnoml
#direction: down
[<abstract> ModelService|
getModels(ids : Array.<string>) : Promise.<object.<string, object>>
]
[StaticModelProvider]--:>[ModelService]
[RootModelProvider]--:>[ModelService]
[PersistedModelProvider]--:>[ModelService]
[ModelAggregator]--:>[ModelService]
[CachingModelDecorator]--:>[ModelService]
[MissingModelDecorator]--:>[ModelService]
[MissingModelDecorator]o-[CachingModelDecorator]
[CachingModelDecorator]o-[ModelAggregator]
[ModelAggregator]o-[StaticModelProvider]
[ModelAggregator]o-[RootModelProvider]
[ModelAggregator]o-[PersistedModelProvider]
[PersistedModelProvider]o-[PersistenceService]
[RootModelProvider]o-[roots]
[StaticModelProvider]o-[models]
```
The platform's model service is responsible for providing domain object
models (effectively, JSON documents describing the persistent state
associated with domain objects.) These are retrieved by identifier.
The platform includes multiple components of this variety:
* `PersistedModelProvider` looks up domain object models from
a persistence store (the [`PersistenceService`](#persistence-service));
this is how user-created and user-modified
domain object models are retrieved.
* `RootModelProvider` provides domain object models that have been
declared via the `roots` extension category. These will appear at the
top level of the tree hierarchy in the user interface.
* `StaticModelProvider` provides domain object models that have been
declared via the `models` extension category. This is useful for
allowing plugins to expose new domain objects declaratively.
* `ModelAggregator` merges together the results from multiple providers.
If multiple providers return models for the same domain object,
the most recently modified version (as determined by the `modified`
property of the model) is chosen.
* `CachingModelDecorator` caches model instances in memory. This
ensures that only a single instance of a domain object model is
present at any given time within the application, and prevent
redundant retrievals.
* `MissingModelDecorator` adds in placeholders when no providers
have returned domain object models for a specific identifier. This
allows the user to easily see that something was expected to be
present, but wasn't.
## Capability Service
```nomnoml
#direction: down
[<abstract> CapabilityService|
getCapabilities(model : object) : object.<string, Function>
]
[CoreCapabilityProvider]--:>[CapabilityService]
[QueuingPersistenceCapabilityDecorator]--:>[CapabilityService]
[CoreCapabilityProvider]o-[capabilities]
[QueuingPersistenceCapabilityDecorator]o-[CoreCapabilityProvider]
```
The capability service is responsible for determining which capabilities
are applicable for a given domain object, based on its model. Primarily,
this is handled by the `CoreCapabilityProvider`, which examines
capabilities exposed via the `capabilities` extension category.
Additionally, `platform/persistence/queue` decorates the persistence
capability specifically to batch persistence attempts among multiple
objects (this allows failures to be recognized and handled in groups.)
## Telemetry Service
```nomnoml
[<abstract> TelemetryService|
requestData(requests : Array.<TelemetryRequest>) : Promise.<object>
subscribe(requests : Array.<TelemetryRequest>) : Function
]<--:[TelemetryAggregator]
```
The telemetry service is responsible for acquiring telemetry data.
Notably, the platform does not include any providers for
`TelemetryService`; applications built on Open MCT Web will need to
implement a provider for this service if they wish to expose telemetry
data. This is usually the most important step for integrating Open MCT Web
into an existing telemetry system.
Requests for telemetry data are usually initiated in the
[presentation layer](#presentation-layer) by some `Controller` referenced
from a view. The `telemetryHandler` service is most commonly used (although
one could also use an object's `telemetry` capability directly) as this
handles capability delegation, by which a domain object such as a Telemetry
Panel can declare that its `telemetry` capability should be handled by the
objects it contains. Ultimately, the request for historical data and the
new subscriptions will reach the `TelemetryService`, and, by way of the
provider(s) which are present for that `TelemetryService`, will pass the
same requests to the back-end.
```nomnoml
[<start> Start]->[Controller]
[Controller]->[<state> declares object of interest]
[declares object of interest]->[TelemetryHandler]
[TelemetryHandler]->[<state> requests telemetry from capabilities]
[TelemetryHandler]->[<state> subscribes to telemetry using capabilities]
[requests telemetry from capabilities]->[TelemetryCapability]
[subscribes to telemetry using capabilities]->[TelemetryCapability]
[TelemetryCapability]->[<state> requests telemetry]
[TelemetryCapability]->[<state> subscribes to telemetry]
[requests telemetry]->[TelemetryService]
[subscribes to telemetry]->[TelemetryService]
[TelemetryService]->[<state> issues request]
[TelemetryService]->[<state> updates subscriptions]
[TelemetryService]->[<state> listens for real-time data]
[issues request]->[<database> Telemetry Back-end]
[updates subscriptions]->[Telemetry Back-end]
[listens for real-time data]->[Telemetry Back-end]
[Telemetry Back-end]->[<end> End]
```
The back-end, in turn, is expected to provide whatever historical
telemetry is available to satisfy the request that has been issue.
```nomnoml
[<start> Start]->[<database> Telemetry Back-end]
[Telemetry Back-end]->[<state> transmits historical telemetry]
[transmits historical telemetry]->[TelemetryService]
[TelemetryService]->[<state> packages telemetry, fulfills requests]
[packages telemetry, fulfills requests]->[TelemetryCapability]
[TelemetryCapability]->[<state> unpacks telemetry per-object, fulfills request]
[unpacks telemetry per-object, fulfills request]->[TelemetryHandler]
[TelemetryHandler]->[<state> exposes data]
[TelemetryHandler]->[<state> notifies controller]
[exposes data]->[Controller]
[notifies controller]->[Controller]
[Controller]->[<state> prepares data for template]
[prepares data for template]->[Template]
[Template]->[<state> displays data]
[displays data]->[<end> End]
```
One peculiarity of this approach is that we package many responses
together at once in the `TelemetryService`, then unpack these in the
`TelemetryCapability`, then repackage these in the `TelemetryHandler`.
The rationale for this is as follows:
* In the `TelemetryService`, we want to have the ability to combine
multiple requests into one call to the back-end, as many back-ends
will support this. It follows that we give the response as a single
object, packages in a manner that allows responses to individual
requests to be easily identified.
* In the `TelemetryCapability`, we want to provide telemetry for a
_single object_, so the telemetry data gets unpacked. This allows
for the unpacking of data to be handled in a single place, and
also permits a flexible substitution method; domain objects may have
implementations of the `telemetry` capability that do not use the
`TelemetryService` at all, while still maintaining compatibility
with any presentation layer code written to utilize this capability.
(This is true of capabilities generally.)
* In the `TelemetryHandler`, we want to group multiple responses back
together again to make it easy for the presentation layer to consume.
In this case, the grouping is different from what may have occurred
in the `TelemetryService`; this grouping is based on what is expected
to be useful _in a specific view_. The `TelemetryService`
may be receiving requests from multiple views.
```nomnoml
[<start> Start]->[<database> Telemetry Back-end]
[Telemetry Back-end]->[<state> notifies client of new data]
[notifies client of new data]->[TelemetryService]
[TelemetryService]->[<choice> relevant subscribers?]
[relevant subscribers?] yes ->[<state> notify subscribers]
[relevant subscribers?] no ->[<state> ignore]
[ignore]->[<end> Ignored]
[notify subscribers]->[TelemetryCapability]
[TelemetryCapability]->[<state> notify listener]
[notify listener]->[TelemetryHandler]
[TelemetryHandler]->[<state> exposes data]
[TelemetryHandler]->[<state> notifies controller]
[exposes data]->[Controller]
[notifies controller]->[Controller]
[Controller]->[<state> prepares data for template]
[prepares data for template]->[Template]
[Template]->[<state> displays data]
[displays data]->[<end> End]
```
The flow of real-time data is similar, and is handled by a sequence
of callbacks between the presentation layer component which is
interested in data and the telemetry service. Providers in the
telemetry service listen to the back-end for new data (via whatever
mechanism their specific back-end supports), package this data in
the same manner as historical data, and pass that to the callbacks
which are associated with relevant requests.
## Persistence Service
```nomnoml
#direction: right
[<abstract> PersistenceService|
listSpaces() : Promise.<Array.<string>>
listObjects() : Promise.<Array.<string>>
createObject(space : string, key : string, document : object) : Promise.<boolean>
readObject(space : string, key : string, document : object) : Promise.<object>
updateObject(space : string, key : string, document : object) : Promise.<boolean>
deleteObject(space : string, key : string, document : object) : Promise.<boolean>
]
[ElasticPersistenceProvider]--:>[PersistenceService]
[ElasticPersistenceProvider]->[<database> ElasticSearch]
[CouchPersistenceProvider]--:>[PersistenceService]
[CouchPersistenceProvider]->[<database> CouchDB]
```
Closely related to the notion of domain objects models is their
persistence. The `PersistenceService` allows these to be saved
and loaded. (Currently, this capability is only used for domain
object models, but the interface has been designed without this idea
in mind; other kinds of documents could be saved and loaded in the
same manner.)
There is no single definitive implementation of a `PersistenceService` in
the platform. Optional adapters are provided to store and load documents
from CouchDB and ElasticSearch, respectively; plugin authors may also
write additional adapters to utilize different back end technologies.
## Action Service
```nomnoml
[ActionService|
getActions(context : ActionContext) : Array.<Action>
]
[ActionProvider]--:>[ActionService]
[CreateActionProvider]--:>[ActionService]
[ActionAggregator]--:>[ActionService]
[LoggingActionDecorator]--:>[ActionService]
[PolicyActionDecorator]--:>[ActionService]
[LoggingActionDecorator]o-[PolicyActionDecorator]
[PolicyActionDecorator]o-[ActionAggregator]
[ActionAggregator]o-[ActionProvider]
[ActionAggregator]o-[CreateActionProvider]
[ActionProvider]o-[actions]
[CreateActionProvider]o-[TypeService]
[PolicyActionDecorator]o-[PolicyService]
```
Actions are discrete tasks or behaviors that can be initiated by a user
upon or using a domain object. Actions may appear as menu items or
buttons in the user interface, or may be triggered by certain gestures.
Responsibilities of platform components of the action service are as
follows:
* `ActionProvider` exposes actions registered via extension category
`actions`, supporting simple addition of new actions. Actions are
filtered down to match action contexts based on criteria defined as
part of an action's extension definition.
* `CreateActionProvider` provides the various Create actions which
populate the Create menu. These are driven by the available types,
so do not map easily ot extension category `actions`; instead, these
are generated after looking up which actions are available from the
[`TypeService`](#type-service).
* `ActionAggregator` merges together actions from multiple providers.
* `PolicyActionDecorator` enforces the `action` policy category by
filtering out actions which violate this policy, as determined by
consulting the [`PolicyService`](#policy-service).
* `LoggingActionDecorator` wraps exposed actions and writes to the
console when they are performed.
## View Service
```nomnoml
[ViewService|
getViews(domainObject : DomainObject) : Array.<View>
]
[ViewProvider]--:>[ViewService]
[PolicyViewDecorator]--:>[ViewService]
[ViewProvider]o-[views]
[PolicyViewDecorator]o-[ViewProvider]
```
The view service provides views that are relevant to a specified domain
object. A "view" is a user-selectable visualization of a domain object.
The responsibilities of components of the view service are as follows:
* `ViewProvider` exposes views registered via extension category
`views`, supporting simple addition of new views. Views are
filtered down to match domain objects based on criteria defined as
part of a view's extension definition.
* `PolicyViewDecorator` enforces the `view` policy category by
filtering out views which violate this policy, as determined by
consulting the [`PolicyService`](#policy-service).
## Policy Service
```nomnoml
[PolicyService|
allow(category : string, candidate : object, context : object, callback? : Function) : boolean
]
[PolicyProvider]--:>[PolicyService]
[PolicyProvider]o-[policies]
```
The policy service provides a general-purpose extensible decision-making
mechanism; plugins can add new extensions of category `policies` to
modify decisions of a known category.
Often, the policy service is referenced from a decorator for another
service, to filter down the results of using that service based on some
appropriate policy category.
The policy provider works by looking up all registered policy extensions
which are relevant to a particular _category_, then consulting each in
order to see if they allow a particular _candidate_ in a particular
_context_; the types for the `candidate` and `context` arguments will
vary depending on the `category`. Any one policy may disallow the
decision as a whole.
```nomnoml
[<start> Start]->[<state> is something allowed?]
[is something allowed?]->[PolicyService]
[PolicyService]->[<state> look up relevant policies by category]
[look up relevant policies by category]->[<state> consult policy #1]
[consult policy #1]->[Policy #1]
[Policy #1]->[<choice> policy #1 allows?]
[policy #1 allows?] no ->[<state> decision disallowed]
[policy #1 allows?] yes ->[<state> consult policy #2]
[consult policy #2]->[Policy #2]

[policy #2 allows?] yes ->[<state> consult policy #3]
[consult policy #3]->[<state> ...]

[policy #n allows?] no ->[<state> decision disallowed]
[policy #n allows?] yes ->[<state> decision allowed]
[decision disallowed]->[<end> Disallowed]
[decision allowed]->[<end> Allowed]
```
The policy decision is effectively an "and" operation over the individual
policy decisions: That is, all policies must agree to allow a particular
policy decision, and the first policy to disallow a decision will cause
the entire decision to be disallowed. As a consequence of this, policies
should generally be written with a default behavior of "allow", and
should only disallow the specific circumstances they are intended to
disallow.
## Type Service
```nomnoml
[TypeService|
listTypes() : Array.<Type>
getType(key : string) : Type
]
[TypeProvider]--:>[TypeService]
[TypeProvider]o-[types]
```
The type service provides metadata about the different types of domain
objects that exist within an Open MCT Web application. The platform
implementation reads these types in from extension category `types`
and wraps them in a JavaScript interface.

# API Refactoring
This document summarizes a path toward implementing API changes
from the [API Redesign](../proposals/APIRedesign.md) for Open MCT Web
v1.0.0.
# Goals
These plans are intended to minimize:
* Waste; avoid allocating effort to temporary changes.
* Downtime; avoid making changes in large increments that blocks
delivery of new features for substantial periods of time.
* Risk; ensure that changes can be validated quickly, avoid putting
large effort into changes that have not been validated.

## Step 1. Imperative bundle registration
Register whole bundles imperatively, using their current format.
For example, in each bundle add a `bundle.js` file:
```js
define([
'mctRegistry',
'json!bundle.json'
], function (mctRegistry, bundle) {
mctRegistry.install(bundle, "path/to/bundle");
});
```
Where `mctRegistry.install` is placeholder API that wires into the
existing bundle registration mechanisms. The main point of entry
would need to be adapted to clearly depend on these bundles
(in the require sense of a dependency), and the framework layer
would need to implement and integrate with this transitional
API.
Benefits:
* Achieves an API Redesign goal with minimal immediate effort.
* Conversion to an imperative syntax may be trivially automated.
* Minimal change; reuse existing bundle definitions, primarily.
* Allows early validation of switch to imperative; unforeseen
consequences of the change may be detected at this point.
* Allows implementation effort to progress in parallel with decisions
about API changes, including fundamental ones such as the role of
Angular. May act in some sense as a prototype to inform those
decisions.
* Creates a location (framework layer) where subsequent changes to
the manner in which extensions are registered may be centralized.
When there is a one-to-one correspondence between the existing
form of an extension and its post-refactor form, adapters can be
written here to defer the task of making changes ubiquitously
throughout bundles, allowing for earlier validation and
verification of those changes, and avoiding ubiquitous changes
which might require us to go dark. (Mitigates
["greenfield paradox"](http://stepaheadsoftware.blogspot.com/2012/09/greenfield-or-refactor-legacy-code-base.html);
want to add value with new API but don't want to discard value
of tested/proven legacy codebase.)
Detriments:
* Requires transitional API to be implemented/supported; this is
waste. May mitigate this by time-bounding the effort put into
this step to ensure that waste is minimal.
Note that API changes at this point do not meaningfully reflect
the desired 1.0.0 API, so no API reviews are necessary.
## Step 2. Incorporate a build step
After the previous step is completed, there should be a
straightforward dependency graph among AMD modules, and an
imperative (albeit transitional) API allowing for other plugins
to register themselves. This should allow for a build step to
be included in a straightforward fashion.
Some goals for this build step:
* Compile (and, preferably, optimize/minify) Open MCT Web
sources into a single `.js` file.
* It is desirable to do the same for HTML sources, but
may wish to defer this until a subsequent refactoring
step if appropriate.
* Provide non-code assets in a format that can be reused by
derivative projects in a straightforward fashion.
Should also consider which dependency/packaging manager should
be used by dependent projects to obtain Open MCT Web. Approaches
include:
1. Plain `npm`. Dependents then declare their dependency with
`npm` and utilize built sources and assets in a documented
fashion. (Note that there are
[documented challenges](http://blog.npmjs.org/post/101775448305/npm-and-front-end-packaging)
in using `npm` in this fashion.)
2. Build with `npm`, but recommend dependents install using
`bower`, as this is intended for front-end development. This may
require checking in built products, however, which
we wish to avoid (this could be solved by maintaining
a separate repository for built products.)
In all cases, there is a related question of which build system
to use for asset generation/management and compilation/minification/etc.
1. [`webpack`](https://webpack.github.io/)
is well-suited in principle, as it is specifically
designed for modules with non-JS dependencies. However,
there may be limitations and/or undesired behavior here
(for instance, CSS dependencies get in-lined as style tags,
removing our ability to control ordering) so it may
2. `gulp` or `grunt`. Commonplace, but both still require
non-trivial coding and/or configuration in order to produce
appropriate build artifacts.
3. [Just `npm`](http://blog.keithcirkel.co.uk/how-to-use-npm-as-a-build-tool/).
Reduces the amount of tooling being used, but may introduce
some complexity (e.g. custom scripts) to the build process,
and may reduce portability.
## Step 3. Separate repositories
Refactor existing applications built on Open MCT Web such that they
are no longer forks, but instead separate projects with a dependency
on the built artifacts from Step 2.
Note that this is achievable already using `bower` (see `warp-bower`
branch at http://developer.nasa.gov/mct/warp for an example.)
However, changes involved in switching to an imperative API and
introducing a build process may change (and should simplify) the
approach used to utilize Open MCT Web as a dependency, so these
changes should be introduced first.
## Step 4. Design registration API
Design the registration API that will replace declarative extension
categories and extensions (including Angular built-ins and composite
services.)
This may occur in parallel with implementation steps.
It will be necessary
to have a decision about the role of Angular at this point; are extensions
registered via provider configuration (Angular), or directly in some
exposed registry?
Success criteria here should be based on peer review. Scope of peer
review should be based on perceived risk/uncertainty surrounding
proposed changes, to avoid waste; may wish to limit this review to
the internal team. (The extent to which external
feedback is available is limited, but there is an inherent timeliness
to external review; need to balance this.)
Benefits:
* Solves the "general case" early, allowing for early validation.
Note that in specific cases, it may be desirable to refactor some
current "extension category" in a manner that will not appear as
registries, _or_ to locate these in different
namespaces, _or_ to remove/replace certain categories entirely.
This work is deferred intentionally to allow for a solution of the
general case.
## Step 5. Imperative extension registration
Register individual extensions imperatively, implementing API changes
from the previous step. At this stage, _usage_ of the API may be confined
to a transitional adapter in the framework layer; bundles may continue
to utilize the transitional API for registering extensions in the
legacy format.
An important, ongoing sub-task here will be to discover and define dependencies
among bundles. Composite services and extension categories are presently
"implicit"; after the API redesign, these will become "explicit", insofar
as some specific component will be responsible for creating any registries.
As such, "bundles" which _use_ specific registries will need to have an
enforceable dependency (e.g. require) upon those "bundles" which
_declare_ those registries.
## Step 6. Refactor individual extensions
Refactor individual extension categories and/or services that have
been identified as needing changes. This includes, but is not
necessarily limited to:
* Views/Representations/Templates (refactored into "components.")
* Capabilities (refactored into "roles", potentially.)
* Telemetry (from `TelemetrySeries` to `TelemetryService`.)
Changes should be made one category at a time (either serially
or separately in parallel) and should involve a tight cycle of:
1. Prioritization/reprioritization; highest-value API improvements
should be done first.
2. Design.
3. Review. Refactoring individual extensions will require significant
effort (likely the most significant effort in the process) so changes
should be validated early to minimize risk/waste.
4. Implementation. These changes will not have a one-to-one relationship
with existing extensions, so changes cannot be centralized; usages
will need to be updated across all "bundles" instead of centralized
in a legacy adapter. If changes are of sufficient complexity, some
planning should be done to spread out the changes incrementally.
By necessity, these changes may break functionality in applications
built using Open MCT Web. On a case-by-case basis, should consider
providing temporary "legacy support" to allow downstream updates
to occur as a separate task; the relevant trade here is between
waste/effort required to maintain legacy support, versus the
downtime which may be introduced by making these changes simultaneously
across several repositories.
## Step 7. Remove legacy bundle support
Update bundles to remove any usages of legacy support for bundles
(including that used by dependent projects.) Then, remove legacy
support from Open MCT Web.
## Step 8. Release candidacy
Once API changes are complete, Open MCT Web should enter a release
candidacy cycle. Important things to look at here:
* Are changes really complete?
* Are they sufficiently documented?
* Are they sufficiently tested?
* Are changes really sufficient?
* Do reviewers think they are usable?
* Does the development team find them useful in practice? This
will require calendar time to ascertain; should allocate time
for this, particularly in alignment with the sprint/release
cycle.
* Has learning curve been measurably decreased? Comparing a to-do
list tutorial to [other examples(http://todomvc.com/) could
provide an empirical basis to this. How much code is required?
How much explanation is required? How many dependencies must
be installed before initial setup?
* Does the API offer sufficient power to implement the extensions we
anticipate?
* Any open API-related issues which should block a 1.0.0 release?
Any problems identified during release candidacy will require
subsequent design changes and planning.
## Step 9. Release
Once API changes have been verified and validated, proceed
with release, including:
* Tagging as version 1.0.0 (at an appropriate time in the
sprint/release cycle.)
* Close any open issues which have been resolved (or made obsolete)
by API changes.

# Reducing interface depth (the bundle.json version)
## Imperitive component registries
Transition component registries to javascript, get rid of bundle.json and bundles.json. Prescribe a method for application configuration, but allow flexibility in how application configuration is defined.
Register components in an imperitive fashion, see angularApp.factory, angularApp.controller, etc. Alternatively, implement our own application object with new registries and it's own form of registering objects.
## Get rid of "extension category" concept.
The concept of an "extension category" is itself an extraneous concept-- an extra layer of interface depth, an extra thing to learn before you can say "hello world". Extension points should be clearly supported and documented with whatever interfaces make sense. Developers who wish to add something that is conceptually equivalent to an extension category can do so directly, in the manner that suites their needs, without us forcing a common method on them.
## Reduce number and depth of extension points
Clearly specify supported extension points (e.g. persistence, model providers, telemetry providers, routes, time systems), but don't claim that the system has a clear and perfect repeatable solution for unknown extension types. New extension categories can be implemented in whatever way makes sense, without prescribing "the one and only system for managing extensions".
The underlying problem here is we are predicting needs for extension points where none exist-- if we try and design the extension system before we know how it is used, we design the wrong thing and have to rewrite it later.
## Composite services should not be the default
Understanding composite services, and describing services as composite services can confuse developers. Aggregators are implemented once and forgotten, while decorators tend to be hacky, brittle solutions that are generally needed to avoid circular imports. While composite services are a useful construct, it reduces interface depth to implement them as registries + typed providers.
You can write a provider (provides "thing x" for "inputs y") with a simple interface. A provider has two or more methods:
* a method which takes "inputs y" and returns True if it knows how to provide "thing x", false otherwise.
* one or more methods which provide "thing x" for objects of "inputs y".
Actually checking whether a provider can respond to a request before asking it to do work allows for faster failure and clearer errors when no providers match the request.
## Get rid of views, representations, and templates.
Templates are an implementation detail that should be handled by module loaders. Views and representations become "components," and a new concept, "routes", is used to exposing specific views to end users.
`components` - building blocks for views, have clear inputs and outputs, and can be coupled to other components when it makes sense. (e.g. parent-child components such as menu and menu item), but should have ZERO knowledge of our data models or telemetry apis. They should define data models that enable them to do their job well while still being easy to test.
`routes` - a view type for a given domain object, e.g. a plot, table, display layout, etc. Can be described as "whatever shows in the main screen when you are viewing an object." Handle loading of data from a domain object and passing that data to the view components. Routes should support editing as it makes sense in their own context.
To facilitate testing:
* routes should be testable without having to test the actual view.
* components should be independently testable with zero knowledge of our data models or telemetry APIs.
Component code should be organized side by side, such as:
```
app
|- components
|- productDetail
| |- productDetail.js
| |- productDetail.css
| |- productDetail.html
| |- productDetailSpec.js
|- productList
|- checkout
|- wishlist
```
Components are not always reusable, and we shouldn't be overly concerned with making them so. If components are heavily reused, they should either be moved to a platform feature (e.g. notifications, indicators), or broken off as an external dependency (e.g. publish mct-plot as mct-plot.js).
# Reducing interface depth (The angular discussion)
Two options here: use more angular, use less angular. Wrapping angular methods does not reduce interface depth and must be avoided.
The primary issue with angular is duplications of concerns-- both angular and the openmctweb platform implement the same tools side by side and it can be hard to comprehend-- it increases interface depth. For other concerns, see footnotes[1].
Wrapping angular methods for non-view related code is confusing to developers because of the random constraints angular places on these items-- developers ultimately have to understand both angular DI and our framework. For example, it's not possible to name the topic service "topicService" because angular expects Services to be implemented by Providers, which is different than our expectation.
To reduce interface depth, we can replace our own provider and registry patterns with angular patterns, or we can only utilize angular view logic, and only use our own DI patterns.
## More angular: for all services
Increasing our commitment to angular would mean using more of the angular factorys, services, etc, and less of our home grown tools. We'd implement our services and extension points as angular providers, and make them configurable via app.config.
As an example, registering a specific type of model provider in angular would look like:
```javascript
mct.provider('model', modelProvider() { /* implementation */});
mct.config(['modelProvider', function (modelProvider) {
modelProvider.providers.push(RootModelProvider);
}]);
```
## Less angular: only for views
If we wish to use less angular, I would recommend discontinuing use of all angular components that are not view related-- services, factories, $http, etc, and implementing them in our own paradigm. Otherwise, we end up with layered interfaces-- one of the goals we would like to avoid.
# Standard packaging and build system
Standardize the packaging and build system, and completely separate the core platform from deployments. Prescribe a starting point for deployments, but allow flexibility.
## Use systemjs for module loading
Allow developers to use whatever module loading system they'd like to use, while still supporting all standard cases. We should also use this system for loading assets (css, scss, html templates), which makes it easier to implement a single file deployment using standard build tooling.
## Use gulp or grunt for standard tooling
Using gulp or grunt as a task runner would bring us in line with standard web developer workflows and help standardize rendering, deployment, and packaging. Additional tools can be added to the workflow at low cost, simplifying the set up of developer environments.
Gulp and grunt provide useful developer tooling such as live reload, automatic scss/less/etc compiliation, and ease of extensibility for standard production build processes. They're key in decoupling code.
## Package openmctweb as single versioned file.
Deployments should depend on a specific version of openmctweb, but otherwise be allowed to have their own deployment and development toolsets.
Customizations and deployments of openmctweb should not use the same build tooling as the core platform; instead they should be free to use their own build tools as they wish. (We would provide a template for an application, based on our experience with warp-for-rp and vista)
Installation and utilization of openmctweb should be as simple as downloading the js file, including it in your own html page, and then initializing an app and running it. If a developer would prefer, they could use bower or npm to handle installation.
Then, if we're using imperative methods for extending the application we can use the following for basic customization:
```html
<script src="//localhost/openmctweb.js"></script>
<script>
// can configure from object
var myApp = new OpenMCTWeb({
persitence: {
providers: [
{
type: 'elastic',
uri: 'http://someElasticHost/'
} // ...
]
}
});
// alternative configurations
myApp.persistence.addProvider(MyPersistenceAdapter);
myApp.model.addProvider(someProviderObject);
// Removing via method
myApp.persistence.removeProvider('some method for removing functionality');
// directly mutating providers
myApp.persistence.providers = [ThisProviderStandsAlone];
//
myApp.run();
</script>
```
This packaging reduces the complexity of managing multiple deployed versions, and also allows us to provide users with incredibly simple tutorials-- they can use whatever tooling they like. For instance, a hello world tutorial may take the option of "exposing a new object in the tree".
```javascript
var myApp = new OpenMCTWeb();
myApp.roots.addRoot({
id: 'myRoot',
name: 'Hello World!',
});
myApp.routes.setDefault('myRoot');
myApp.run();
```
# Misc Improvements
## Refresh on navigation
In cases where navigation events change the entire screen, we should be using routes and location changes to navigate between objects. We should be using href for all navigation events.
At the same time, navigating should refresh state of every visible object. A properly configured persistence store will handle caching with standard cache headers and 304 not modified responses, which will provide good performance of object reloads, while helping us ensure that objects are always in sync between clients.
View state (say, the expanded tree nodes) should not be tied to caching of data-- it should be something we intentionally persist and restore with each navigation. Data (such as object definitions) should be reloaded from server as necessary to restore state.
## Move persistence adapter to promise rejection.
Simple: reject on fail, resolve on success.
## Remove bulk requests from providers
Aggregators can request multiple things at once, but individual providers should only have to implement handling at the level of a single request. Each provider can implement it's own internal batching, but it should support making requests at a finer level of detail.
Excessive wrapping of code with $q.all causes additional digest cycles and decreased performance.
For example, instead of every telemetry provider responding to a given telemetry request, aggregators should route each request to the first provider that can fulfill that request.
# Notes on current API proposals:
* [RequireJS for Dependency Injection](https://github.com/nasa/openmctweb/blob/api-redesign/docs/src/design/proposals/APIRedesign.md#requirejs-as-dependency-injector): requires other topics to be discussed first.
* [Arbitrary HTML Views](https://github.com/nasa/openmctweb/blob/api-redesign/docs/src/design/proposals/APIRedesign.md#arbitrary-html-views): think there is a place for it, requires other topics to be discussed first.
* [Wrap Angular Services](https://github.com/nasa/openmctweb/blob/api-redesign/docs/src/design/proposals/APIRedesign.md#wrap-angular-services): No, this is bad.
* [Bundle definitions in Javascript](https://github.com/nasa/openmctweb/blob/api-redesign/docs/src/design/proposals/APIRedesign.md#bundle-declarations-in-javascript): Points to a solution, but ultimately requires more discussion.
* [pass around a dependency injector](https://github.com/nasa/openmctweb/blob/api-redesign/docs/src/design/proposals/APIRedesign.md#pass-around-a-dependency-injector): No.
* [remove partial constructors](https://github.com/nasa/openmctweb/blob/api-redesign/docs/src/design/proposals/APIRedesign.md#remove-partial-constructors): Yes, this should be superseded by another proposal though. The entire concept was a messy solution to dependency injection issues caused by declarative syntax.
* [Rename views to applications](https://github.com/nasa/openmctweb/blob/api-redesign/docs/src/design/proposals/APIRedesign.md#rename-views-to-applications): Points to a problem that needs to be solved but I think the name is bad.
* [Provide classes for extensions](https://github.com/nasa/openmctweb/blob/api-redesign/docs/src/design/proposals/APIRedesign.md#provide-classes-for-extensions): Yes, in specific places
* [Normalize naming conventions](https://github.com/nasa/openmctweb/blob/api-redesign/docs/src/design/proposals/APIRedesign.md#normalize-naming-conventions): Yes.
* [Expose no third-party APIs](https://github.com/nasa/openmctweb/blob/api-redesign/docs/src/design/proposals/APIRedesign.md#expose-no-third-party-apis): Completely disagree, points to a real problem with poor angular integration.
* [Register Extensions as Instances instead of Constructors](https://github.com/nasa/openmctweb/blob/api-redesign/docs/src/design/proposals/APIRedesign.md#register-extensions-as-instances-instead-of-constructors): Superseded by the fact that we should not hope to implement a generic construct.
* [Remove capability delegation](https://github.com/nasa/openmctweb/blob/api-redesign/docs/src/design/proposals/APIRedesign.md#remove-capability-delegation): Yes.
* [Nomenclature Change](https://github.com/nasa/openmctweb/blob/api-redesign/docs/src/design/proposals/APIRedesign.md#nomenclature-change): Yes, hope to discuss the implications of this more clearly in other proposals.
* [Capabilities as mixins](https://github.com/nasa/openmctweb/blob/api-redesign/docs/src/design/proposals/APIRedesign.md#capabilities-as-mixins): Yes.
* [Remove appliesTo methods](https://github.com/nasa/openmctweb/blob/api-redesign/docs/src/design/proposals/APIRedesign.md#remove-applies-to-methods): No-- I think some level of this is necessary. I think a more holistic approach to policy is needed. it's a rather complicated system.
* [Revise telemetry API](https://github.com/nasa/openmctweb/blob/api-redesign/docs/src/design/proposals/APIRedesign.md#revise-telemetry-api): If we can rough out and agree to the specifics, then Yes. Needs discussion.
* [Allow composite services to fail gracefully](https://github.com/nasa/openmctweb/blob/api-redesign/docs/src/design/proposals/APIRedesign.md#allow-composite-services-to-fail-gracefully): No. As mentioned above, I think composite services themselves should be eliminated for a more purpose bound tool.
* [Plugins as angular modules](https://github.com/nasa/openmctweb/blob/api-redesign/docs/src/design/proposals/APIRedesign.md#plugins-as-angular-modules): Should we decide to embrace Angular completely, I would support this. Otherwise, no.
* [Contextual Injection](https://github.com/nasa/openmctweb/blob/api-redesign/docs/src/design/proposals/APIRedesign.md#contextual-injection): No, don't see a need.
* [Add New Abstractions for Actions](https://github.com/nasa/openmctweb/blob/api-redesign/docs/src/design/proposals/APIRedesign.md#add-new-abstractions-for-actions): Worth a discussion.
* [Add gesture handlers](https://github.com/nasa/openmctweb/blob/api-redesign/docs/src/design/proposals/APIRedesign.md#add-gesture-handlers): Yes if we can agree on details. We need a platform implementation that is easy to use, but we should not reinvent the wheel.
# [1] Footnote: The angular debacle
## "Do or do not, there is no try"
A commonly voiced concern of embracing angular is the possibility of becoming dependent on a third party framework. This concern is itself detrimental-- if we're afraid of becoming dependent on a third party framework, then we will do a bad job of using the framework, and inevitably will want to stop using it.
If we're using a framework, we need to use it fully, or not use it at all.
## A lack of commitment
A number of the concerns we heard from developers and interns can be attributed to the tenuous relationship between the OpenMCTWeb platform and angular. We claimed to be angular, but we weren't really angular. Instead, we are caught between our incomplete framework paradigm and the angular paradigm. In many cases we reinvented the wheel or worked around functionality that angular provides, and ended up in a more confusing state.
## Commitment is good!
We could just be an application that is built with angular.
An application that is modular and extensible not because it reinvents tools for providing modularity and extensibility, but because it reuses existing tools for modularity and extensibility.
There are benefits to buying into the angular paradigm: shift documentation burden to external project, engage a larger talent pool available both as voluntary open source contributors and as experienced developers for hire, and gain access to an ecosystem of tools that we can use to increase the speed of development.
There are negatives too: Angular is a monolith, it has performance concerns, and an unclear future. If we can't live with it, we should look at alternatives.

# Imperative Plugins
This is a design proposal for handling
[bundle declarations in JavaScript](
APIRedesign.md#bundle-declarations-in-javascript).
## Developer Use Cases
Developers will want to use bundles/plugins to (in rough order
of occurrence):
1. Add new extension instances.
2. Use existing services
3. Add new service implementations.
4. Decorate service implementations.
5. Decorate extension instances.
6. Add new types of services.
7. Add new extension categories.
Notably, bullets 4 and 5 above are currently handled implicitly,
which has been cited as a source of confusion.
## Interfaces
Two base classes may be used to satisfy these use cases:
* The `CompositeServiceFactory` provides composite service instances.
Decorators may be added; the approach used for compositing may be
modified; and individual services may be registered to support compositing.
* The `ExtensionRegistry` allows for the simpler case where what is desired
is an array of all instances of some kind of thing within the system.
Note that additional developer use cases may be supported by using the
more general-purpose `Registry`
```nomnoml
[Factory.<T, V>
|
- factoryFn : function (V) : T
|
+ decorate(decoratorFn : function (T, V) : T, options? : RegistrationOptions)
]-:>[function (V) : T]
[RegistrationOptions |
+ priority : number or string
]
[Registry.<T, V>
|
- compositorFn : function (Array.<T>) : V
|
+ register(item : T, options? : RegistrationOptions)
+ composite(compositorFn : function (Array.<T>) : V, options? : RegistrationOptions)
]-:>[Factory.<V, Void>]
[Factory.<V, Void>]-:>[Factory.<T, V>]
[ExtensionRegistry.<T>]-:>[Registry.<T, Array.<T>>]
[Registry.<T, Array.<T>>]-:>[Registry.<T, V>]
[CompositeServiceFactory.<T>]-:>[Registry.<T, T>]
[Registry.<T, T>]-:>[Registry.<T, V>]
```
## Examples
### 1. Add new extension instances.
```js
// Instance-style registration
mct.types.register(new mct.Type({
key: "timeline",
name: "Timeline",
description: "A container for activities ordered in time."
});
// Factory-style registration
mct.actions.register(function (domainObject) {
return new RemoveAction(domainObject);
}, { priority: 200 });
```
### 2. Use existing services
```js
mct.actions.register(function (domainObject) {
var dialogService = mct.ui.dialogServiceFactory();
return new PropertiesAction(dialogService, domainObject);
});
```
### 3. Add new service implementations
```js
// Instance-style registration
mct.persistenceServiceFactory.register(new LocalPersistenceService());
// Factory-style registration
mct.persistenceServiceFactory.register(function () {
var $http = angular.injector(['ng']).get('$http');
return new LocalPersistenceService($http);
});
```
### 4. Decorate service implementations
```js
mct.modelServiceFactory.decorate(function (modelService) {
return new CachingModelDecorator(modelService);
}, { priority: 100 });
```
### 5. Decorate extension instances
```js
mct.capabilities.decorate(function (capabilities) {
return capabilities.map(decorateIfApplicable);
});
```
This use case is not well-supported by these API changes. The most
common case for decoration is capabilities, which are under reconsideration;
should consider handling decoration of capabilities in a different way.
### 6. Add new types of services
```js
myModule.myServiceFactory = new mct.CompositeServiceFactory();
// In cases where a custom composition strategy is desired
myModule.myServiceFactory.composite(function (services) {
return new MyServiceCompositor(services);
});
```
### 7. Add new extension categories.
```js
myModule.hamburgers = new mct.ExtensionRegistry();
```
## Evaluation
### Benefits
* Encourages separation of registration from declaration (individual
components are decoupled from the manner in which they are added
to the architecture.)
* Minimizes "magic." Dependencies are acquired, managed, and exposed
using plain-old-JavaScript without any dependency injector present
to obfuscate what is happening.
* Offers comparable expressive power to existing APIs; can still
extend the behavior of platform components in a variety of ways.
* Does not force or limit formalisms to use;
### Detriments
* Does not encourage separation of dependency acquisition from
declaration; that is, it would be quite natural using this API
to acquire references to services during the constructor call
to an extension or service. But, passing these in as constructor
arguments is preferred (to separate implementation from architecture.)
* Adds (negligible?) boilerplate relative to declarative syntax.
* Relies on factories, increasing number of interfaces to be concerned
with.

# Roles
Roles are presented as an alternative formulation to capabilities
(dynamic behavior associated with individual domain objects.)
Specific goals here:
* Dependencies of individual scripts should be clear.
* Domain objects should be able to selectively exhibit a wide
variety of behaviors.
## Developer Use Cases
1. Checking for the existence of behavior.
2. Using behavior.
3. Augmenting existing behaviors.
4. Overriding existing behaviors.
5. Adding new behaviors.
## Overview of Proposed Solution
Remove `getCapability` from domain objects; add roles as external
services which can be applied to domain objects.
## Interfaces
```nomnoml
[Factory.<T, V>
|
- factoryFn : function (V) : T
|
+ decorate(decoratorFn : function (T, V) : T, options? : RegistrationOptions)
]-:>[function (V) : T]
[RegistrationOptions |
+ priority : number or string
]<:-[RoleOptions |
+ validate : function (DomainObject) : boolean
]
[Role.<T> |
+ validate(domainObject : DomainObject) : boolean
+ decorate(decoratorFn : function (T, V) : T, options? : RoleOptions)
]-:>[Factory.<T, DomainObject>]
[Factory.<T, DomainObject>]-:>[Factory.<T, V>]
```
## Examples
### 1. Checking for the existence of behavior
```js
function PlotViewPolicy(telemetryRole) {
this.telemetryRole = telemetryRole;
}
PlotViewPolicy.prototype.allow = function (view, domainObject) {
return this.telemetryRole.validate(domainObject);
};
```
### 2. Using behavior
```js
PropertiesAction.prototype.perform = function () {
var mutation = this.mutationRole(this.domainObject);
return this.showDialog.then(function (newModel) {
return mutation.mutate(function () {
return newModel;
});
});
};
```
### 3. Augmenting existing behaviors
```js
// Non-Angular style
mct.roles.persistenceRole.decorate(function (persistence) {
return new DecoratedPersistence(persistence);
});
// Angular style
myModule.decorate('persistenceRole', ['$delegate', function ($delegate) {
return new DecoratedPersistence(persistence);
}]);
```
### 4. Overriding existing behaviors
```js
// Non-Angular style
mct.roles.persistenceRole.decorate(function (persistence, domainObject) {
return domainObject.getModel().type === 'someType' ?
new DifferentPersistence(domainObject) :
persistence;
}, {
validate: function (domainObject, next) {
return domainObject.getModel().type === 'someType' || next();
}
});
```
### 5. Adding new behaviors
```js
function FooRole() {
mct.Role.apply(this, [function (domainObject) {
return new Foo(domainObject);
}]);
}
FooRole.prototype = Object.create(mct.Role.prototype);
FooRole.prototype.validate = function (domainObject) {
return domainObject.getModel().type === 'some-type';
};
//
myModule.roles.fooRole = new FooRole();
```
## Evaluation
### Benefits
* Simplifies/standardizes augmentation or replacement of behavior associated
with specific domain objects.
* Minimizes number of abstractions; roles are just factories.
* Clarifies dependencies; roles used must be declared/acquired in the
same manner as services.
### Detriments
* Externalizes functionality which is conceptually associated with a
domain object.
* Relies on factories, increasing number of interfaces to be concerned
with.

# Security Guide
Open MCT is a rich client with plugin support that executes as a single page
web application in a browser environment. Security concerns and
vulnerabilities associated with the web as a platform should be considered
before deploying Open MCT (or any other web application) for mission or
production usage.
This document describes several important points to consider when developing
for or deploying Open MCT securely. Other resources such as
[Open Web Application Security Project (OWASP)](https://www.owasp.org)
provide a deeper and more general overview of security for web applications.
## Security Model
Open MCT has been architected assuming the following deployment pattern:
* A tagged, tested Open MCT version will be used.
* Externally authored plugins will be installed.
* A server will provide persistent storage, telemetry, and other shared data.
* Authorization, authentication, and auditing will be handled by a server.
## Security Procedures
The Open MCT team secures our code base using a combination of code review,
dependency review, and periodic security reviews. Static analysis performed
during automated verification additionally safeguards against common
coding errors which may result in vulnerabilities.
### Code Review
All contributions are reviewed by internal team members. External
contributors receive increased scrutiny for security and quality,
and must sign a licensing agreement.
### Dependency Review
Before integrating third-party dependencies, they are reviewed for security
and quality, with consideration given to authors and users of these
dependencies, as well as review of open source code.
### Periodic Security Reviews
Open MCT's code, design, and architecture are periodically reviewed
(approximately annually) for common security issues, such as the
[OWASP Top Ten](https://www.owasp.org/index.php/Category:OWASP_Top_Ten_Project).
## Security Concerns
Certain security concerns deserve special attention when deploying Open MCT,
or when authoring plugins.
### Identity Spoofing
Open MCT issues calls to web services with the privileges of a logged in user.
Compromised sources (either for Open MCT itself or a plugin) could
therefore allow malicious code to execute with those privileges.
To avoid this:
* Serve Open MCT and other scripts over SSL (https rather than http)
to prevent man-in-the-middle attacks.
* Exercise precautions such as security reviews for any plugins or
applications built for or with Open MCT to reject malicious changes.
### Information Disclosure
If Open MCT is used to handle or display sensitive data, any components
(such as adapter plugins) must take care to avoid leaking or disclosing
this information. For example, avoid sending sensitive data to third-party
servers or insecure APIs.
### Data Tampering
The web application architecture leaves open the possibility that direct
calls will be made to back-end services, circumventing Open MCT entirely.
As such, Open MCT assumes that server components will perform any necessary
data validation during calls issues to the server.
Additionally, plugins which serialize and write data to the server must
escape that data to avoid database injection attacks, and similar.
### Repudiation
Open MCT assumes that servers log any relevant interactions and associates
these with a user identity; the specific user actions taken within the
application are assumed not to be of concern for auditing.
In the absence of server-side logging, users may disclaim (maliciously,
mistakenly, or otherwise) actions taken within the system without any
way to prove otherwise.
If keeping client-level interactions is important, this will need to be
implemented via a plugin.
### Denial-of-service
Open MCT assumes that server-side components will be insulated against
denial-of-service attacks. Services should only permit resource-intensive
tasks to be initiated by known or trusted users.
### Elevation of Privilege
Corollary to the assumption that servers guide against identity spoofing,
Open MCT assumes that services do not allow a user to act with
inappropriately escalated privileges. Open MCT cannot protect against
such escalation; in the clearest case, a malicious actor could interact
with web services directly to exploit such a vulnerability.
## Additional Reading
The following resources have been used as a basis for identifying potential
security threats to Open MCT deployments in preparation of this document:
* [STRIDE model](https://www.owasp.org/index.php/Threat_Risk_Modeling#STRIDE)
* [Attack Surface Analysis Cheat Sheet](https://www.owasp.org/index.php/Attack_Surface_Analysis_Cheat_Sheet)

### Testathons
Testathons can be used as a means of performing per-sprint and per-release testing.
#### Timing
For per-sprint testing, a testathon is typically performed at the beginning of the third week of a sprint, and again later that week to verify any fixes. For per-release testing, a testathon is typically performed prior to any formal testing processes that are applicable to that release.
#### Process
1. Prior to the scheduled testathon, a list will be compiled of all issues that are closed and unverified.
2. For each issue, testers should review the associated PR for testing instructions. See the contributing guide for instructions on [pull requests](https://github.com/nasa/openmct/blob/master/CONTRIBUTING.md#merging).
3. As each issue is verified via testing, any team members testing it should leave a comment on that issue indicating that it has been verified fixed.
4. If a bug is found that relates to an issue being tested, notes should be included on the associated issue, and the issue should be reopened. Bug notes should include reproduction steps.
5. For any bugs that are not obviously related to any of the issues under test, a new issue should be created with details about the bug, including reproduction steps. If unsure about whether a bug relates to an issue being tested, just create a new issue.
6. At the end of the testathon, triage will take place, where all tested issues will be reviewed.
7. If verified fixed, an issue will remain closed, and will have the “unverified” label removed.
8. For any bugs found, a severity will be assigned.
9. A second testathon will be scheduled for later in the week that will aim to address all issues identified as blockers, as well as any other issues scoped by the team during triage.
10. Any issues that were not tested will remain "unverified" and will be picked up in the next testathon.

# Test Procedures
## Introduction
This document is intended to be used:
* By testers, to verify that Open MCT Web behaves as specified.
* By the development team, to document new test cases and to provide
guidance on how to author these.
## Writing Procedures
### Template
Procedures for individual tests should use the following template,
adapted from [https://swehb.nasa.gov/display/7150/SWE-114]().
Property | Value
---------------|---------------------------------------------------------------
Test ID |
Relevant reqs. |
Prerequisites |
Test input |
Instructions |
Expectation |
Eval. criteria |
For multi-line descriptions, use an asterisk or similar indicator to refer
to a longer-form description below.
#### Example Procedure - Edit a Layout
Property | Value
---------------|---------------------------------------------------------------
Test ID | MCT-TEST-000X - Edit a layout
Relevant reqs. | MCT-EDIT-000Y
Prerequisites | Create a layout, as in MCT-TEST-000Z
Test input | Domain object database XYZ
Instructions | See below &ast;
Expectation | Change to editing context &dagger;
Eval. criteria | Visual inspection
&ast; Follow the following steps:
1. Verify that the created layout is currently navigated-to,
as in MCT-TEST-00ZZ.
2. Click the Edit button, identified by a pencil icon and the text "Edit"
displayed on hover.
&dagger; Right-hand viewing area should be surrounded by a dashed
blue border when a domain object is being edited.
### Guidelines
Test procedures should be written assuming minimal prior knowledge of the
application: Non-standard terms should only be used when they are documented
in [the glossary](#glossary), and shorthands used for user actions should
be accompanied by useful references to test procedures describing those
actions (when available) or descriptions in user documentation.
Test cases should be narrow in scope; if a list of steps is excessively
long (or must be written vaguely to be kept short) it should be broken
down into multiple tests which reference one another.
All requirements satisfied by Open MCT Web should be verifiable using
one or more test procedures.
## Glossary
This section will contain terms used in test procedures. This may link to
a common glossary, to avoid replication of content.
## Procedures
This section will contain specific test procedures. Presently, procedures
are placeholders describing general patterns for setting up and conducting
testing.
### User Testing Setup
These procedures describes a general pattern for setting up for user
testing. Specific deployments should customize this pattern with
relevant data and any additional steps necessary.
Property | Value
---------------|---------------------------------------------------------------
Test ID | MCT-TEST-SETUP0 - User Testing Setup
Relevant reqs. | TBD
Prerequisites | Build of relevant components
Test input | Exemplary database; exemplary telemetry data set
Instructions | See below
Expectation | Able to load application in a web browser (Google Chrome)
Eval. criteria | Visual inspection
Instructions:
1. Start telemetry server.
2. Start ElasticSearch.
3. Restore database snapshot to ElasticSearch.
4. Start telemetry playback.
5. Start HTTP server for client sources.
### User Test Procedures
Specific user test cases have not yet been authored. In their absence,
user testing is conducted by:
* Reviewing the text of issues from the issue tracker to understand the
desired behavior, and exercising this behavior in the running application.
(For instance, by following steps to reproduce from the original issue.)
* Issues which appear to be resolved should be marked as such with comments
on the original issue (e.g. "verified during user testing MM/DD/YYYY".)
* Issues which appear not to have been resolved should be reopened with an
explanation of what unexpected behavior has been observed.
* In cases where an issue appears resolved as-worded but other related
undesirable behavior is observed during testing, a new issue should be
opened, and linked to from a comment in the original issues.
* General usage of new features and/or existing features which have undergone
recent changes. Defects or problems with usability should be documented
by filing issues in the issue tracker.
* Open-ended testing to discover defects, identify usability issues, and
generate feature requests.
### Long-Duration Testing
The purpose of long-duration testing is to identify performance issues
and/or other defects which are sensitive to the amount of time the
application is kept running. (Memory leaks, for instance.)
Property | Value
---------------|---------------------------------------------------------------
Test ID | MCT-TEST-LDT0 - Long-duration Testing
Relevant reqs. | TBD
Prerequisites | MCT-TEST-SETUP0
Test input | (As for test setup.)
Instructions | See "Instructions" below &ast;
Expectation | See "Expectations" below &dagger;
Eval. criteria | Visual inspection
&ast; Instructions:
1. Start `top` or a similar tool to measure CPU usage and memory utilization.
2. Open several user-created displays (as many as would be realistically
opened during actual usage in a stressing case) in some combination of
separate tabs and windows (approximately as many tabs-per-window as
total windows.)
3. Ensure that playback data is set to run continuously for at least 24 hours
(e.g. on a loop.)
4. Record CPU usage and memory utilization.
5. In at least one tab, try some general user interface gestures and make
notes about the subjective experience of using the application. (Particularly,
the degree of responsiveness.)
6. Leave client displays open for 24 hours.
7. Record CPU usage and memory utilization again.
8. Make additional notes about the subjective experience of using the
application (again, particularly responsiveness.)
9. Check logs for any unexpected warnings or errors.
&dagger; Expectations:
* At the end of the test, CPU usage and memory usage should both be similar
to their levels at the start of the test.
* At the end of the test, subjective usage of the application should not
be observably different from the way it was at the start of the test.
(In particular, responsiveness should not decrease.)
* Logs should not contain any unexpected warnings or errors ("expected"
warnings or errors are those that have been documented and prioritized
as known issues, or those that are explained by transient conditions
external to the software, such as network outages.)

numbers by the following process:
1. Update version number in `package.json`
1. Checkout branch created for the last sprint that has been successfully tested.
2. Remove a `-SNAPSHOT` suffix from the version in `package.json`.
3. Verify that resulting version number meets semantic versioning
requirements relative to previous stable version. Increment the
version number if necessary.
4. If version is considered unstable (which may be the case during
1. Remove `-SNAPSHOT` suffix.
2. Verify that resulting version number meets semantic versioning
requirements relative to previous stable version. Increment if
necessary.
3. If version is considered unstable (which may be the case during
the first three sprints of a release), apply a new suffix per
[Version Numbering](#version-numbering) guidance above.
2. Tag the release.
1. Commit changes to `package.json` on the new branch created in
the previous step.
1. Commit changes to `package.json` on the `master` branch.
The commit message should reference the sprint being closed,
preferably by a URL reference to the associated Milestone in
GitHub.
2. Verify that build still completes, that application passes
smoke-testing, and that only differences from tested versions
are the changes to version number above.
3. Push the new branch.
3. Push the `master` branch.
4. Tag this commit with the version number, prepending the letter "v".
(e.g. `git tag v0.9.3-alpha`)
5. Push the tag to GitHub. (e.g. `git push origin v0.9.3-alpha`).
3. Upload a release archive.
1. Use the [GitHub release interface](https://github.com/nasa/openmct/releases)
1. Run `npm pack` to generate the archive.
2. Use the [GitHub release interface](https://github.com/nasa/openmct/releases)
to draft a new release.
2. Choose the existing tag for the new version (created and pushed above.)
3. Choose the existing tag for the new version (created and pushed above.)
Enter the tag name as the release name as well; see existing releases
for examples. (e.g. `Open MCT v0.9.3-alpha`)
3. Designate the release as a "pre-release" as appropriate (for instance,
for examples.
4. Attach the release archive.
5. Designate the release as a "pre-release" as appropriate (for instance,
when the version number has been suffixed as unstable, or when
the version number is below 1.0.0.)
4. Add release notes including any breaking changes, enhancements,
bug fixes with solutions in brief.
5. Publish the release.
4. Publish the release to npm
1. Login to npm
2. Checkout the tag created in the previous step.
3. In `package.json` change package to be public (private: false)
4. Test the package before publishing by doing `npm publish --dry-run`
if necessary.
5. Publish the package to the npmjs registry (e.g. `npm publish --access public`)
NOTE: Use the `--tag unstable` flag to the npm publishj if this is a prerelease.
6. Confirm the package has been published (e.g. `https://www.npmjs.com/package/openmct`)
5. Update snapshot status in `package.json`
1. Create a new branch off the `master` branch.
2. Remove any suffix from the version number,
or increment the _patch_ version if there is no suffix.
3. Append a `-SNAPSHOT` suffix.
4. Commit changes to `package.json` on the `master` branch.
4. Restore snapshot status in `package.json`
1. Remove any suffix from the version number, or increment the
_patch_ version if there is no suffix.
2. Append a `-SNAPSHOT` suffix.
3. Commit changes to `package.json` on the `master` branch.
The commit message should reference the sprint being opened,
preferably by a URL reference to the associated Milestone in
GitHub.
5. Verify that build still completes, that application passes
4. Verify that build still completes, that application passes
smoke-testing.
6. Create a PR to be merged into the `master` branch.
5. Push the `master` branch.
