+#### 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 you’re 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/).

 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 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`.

-# 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. _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|
-  [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'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 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'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, 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 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.
-
-The target audience includes:
-
-* _Platform maintainers_: Individuals involved in developing,
-  extending, and maintaining capabilities of the platform.
-* _Integration developers_: Individuals tasked with integrated
-  Open MCT 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 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]->[Browser APIs]]]
-[Server|[Web services]]
-[Client]<->[Server]
-```
-
-While Open MCT 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 to interact with these services.
-
-Typically, the pattern here is to provide a known interface that
-Open MCT 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 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|
-  [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. 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. 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,
-  as well as optional features (such as Plot view) included alongside
-  the platform.

-# Overview
-
-The Open MCT 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 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 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 Angular’s 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 look-and-feel 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. User-facing 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, 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 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 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 (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 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 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, 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 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'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 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 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'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 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]

-[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 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
-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 to 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]->[<choice> policy #2 allows?]
-[policy #2 allows?] no ->[<state> decision disallowed]
-[policy #2 allows?] yes ->[<state> consult policy #3]
-[consult policy #3]->[<state> ...]
-[...]->[<state> consult policy #n]
-[consult policy #n]->[Policy #n]
-[Policy #n]->[<choice> policy #n allows?]
-[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 application. The platform
-implementation reads these types in from extension category `types`
-and wraps them in a JavaScript interface.

-
-## 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
-  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. 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 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 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. 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.
-
-## Step 8. Release candidacy
-
-Once API changes are complete, Open MCT 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)
-
-## Imperative 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 imperative 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 factories, 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 setup of developer environments.
-
-Gulp and grunt provide useful developer tooling such as live reload, automatic scss/less/etc compilation, 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.

-## Introduction
-
-This document is intended to be used:
-
-* By testers, to verify that Open MCT 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 *
-Expectation    | Change to editing context †
-Eval. criteria | Visual inspection
-
-* 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.
-
-† 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 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
----------------|---------------------------------------------------------------

-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)

-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

-Prerequisites  | MCT-TEST-SETUP0
-Test input     | (As for test setup.)
-Instructions   | See "Instructions" below *
-Expectation    | See "Expectations" below †
-Eval. criteria | Visual inspection
-
-* 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.
-
-† 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.)

+more resilient to change and therefor a better indicator of failure. Smoke tests will also run quickly
+as they cover a very "thin surface" of functionality.
+
+When deciding between authoring new smoke tests or functional tests, ask yourself "would I feel
+comfortable running this test during a live mission?" Avoid creating or deleting Domain Objects.
+Make no assumptions about the order that elements appear in the DOM.
