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.
* [_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): The information model
describes the state and behavior of the objects with which the user
interacts.
* [_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.
