-# Open MCT API
+# Building Applications With Open MCT

-The Open MCT framework public api can be utilized by building the application
-(`gulp install`) and then copying the file from `dist/main.js` to your
-directory of choice.
+## Scope and purpose of this document

-Open MCT supports AMD, CommonJS, and loading via a script tag; it's easy to use
-in your project. The [`openmct`]{@link module:openmct} module is exported
-via AMD and CommonJS, and is also exposed as `openmct` in the global scope
-if loaded via a script tag.
+This document is intended to serve as a reference for developing an application 
+based on Open MCT. It will provide details of the API functions necessary to extend the 
+Open MCT platform meet common use cases such as integrating with a telemetry source. 

-## Overview
+The best place to start is with the [Open MCT Tutorials](https://github.com/nasa/openmct-tutorial). 
+These will walk you through the process of getting up and running with Open MCT, 
+as well as addressing some common developer use cases.

-Open MCT's goal is to allow you to browse, create, edit, and visualize all of
-the domain knowledge you need on a daily basis.
+## Building From Source 

-To do this, the main building block provided by Open MCT is the _domain object_.
-The temperature sensor on the starboard solar panel,
-an overlay plot comparing the results of all temperature sensor,
-the command dictionary for a spacecraft,
-the individual commands in that dictionary, your "my documents" folder:
+The latest version of Open MCT is available from [our GitHub repository](https://github.com/nasa/openmct). 
+If you have `git`, and `node` installed, you can build Open MCT with the commands 
+```
+git clone https://github.com/nasa/openmct.git
+cd openmct
+npm install
+```
+
+These commands will fetch the Open MCT source from our GitHub repository, and build 
+a minified version that can be included in your application. The output of the 
+build process is placed in a `dist` folder under the openmct source directory, 
+which can be copied out to another location as needed. The contents of this 
+folder will include a minified javascript file named `openmct.js` as well as 
+assets such as html, css, and images necessary for the UI. 
+
+## Starting an Open MCT application
+
+To start a minimally functional Open MCT application, it is necessary to include 
+the Open MCT distributable, enable some basic plugins, and bootstrap the application. 
+The tutorials walk through the process of getting Open MCT up and running from scratch,
+but provided below is a minimal HTML template that includes Open MCT, installs 
+some basic plugins, and bootstraps the application. It assumes that Open MCT is 
+installed under an `openmct` subdirectory, as described in [Building From Source](#building-from-source). 
+
+This approach includes openmct using a simple script tag, resulting in a global 
+variable named `openmct`. This `openmct` object is used subsequently to make API 
+calls. 
+
+Open MCT is packaged as a UMD (Universal Module Definition) module, so common 
+script loaders are also supported.
+
+```html
+<!DOCTYPE html>
+<html>
+<head>
+    <title>Open MCT</title>
+    <script src="openmct.js"></script>
+</head>
+<body>
+    <script>
+        openmct.setAssetPath('openmct/dist');
+        openmct.install(openmct.plugins.LocalStorage());
+        openmct.install(openmct.plugins.MyItems());
+        openmct.install(openmct.plugins.UTCTimeSystem());
+        openmct.install(openmct.plugins.Espresso());
+        openmct.start();
+    </script>
+</body>
+</html>
+```
+
+The Open MCT library included above requires certain assets such as html templates, 
+images, and css. If you installed Open MCT from GitHub as described in the section 
+on [Building from Source](#building-from-source) then these assets will have been 
+downloaded along with the Open MCT javascript library. You can specify the 
+location of these assets by calling `openmct.setAssetPath()`. Typically this will 
+be the same location as the `openmct.js` library is included from.
+
+There are some plugins bundled with the application that provide UI, persistence, 
+and other default configuration which are necessary to be able to do anything with 
+the application initially. Any of these plugins can, in principle, be replaced with a custom 
+plugin. The included plugins are documented in the [Included Plugins](#included-plugins) 
+section.  
+
+## Plugins
+
+### Defining and Installing a New Plugin
+
+```javascript
+openmct.install(function install(openmctAPI) {
+    // Do things here
+    // ...
+});
+```
+
+New plugins are installed in Open MCT by calling `openmct.install`, and providing 
+a plugin installation function. This function will be invoked on application 
+startup with one parameter - the openmct API object. A common approach used in 
+the Open MCT codebase is to define a plugin as a function that returns this 
+installation function. This allows configuration to be specified when the plugin is included.
+
+eg.
+```javascript
+openmct.install(openmct.plugins.Elasticsearch("http://localhost:8002/openmct"));
+```
+This approach can be seen in all of the [plugins provided with Open MCT](https://github.com/nasa/openmct/blob/master/src/plugins/plugins.js).
+
+## Domain Objects and Identifiers
+
+_Domain Objects_ are the basic entities that represent domain knowledge in Open MCT.
+The temperature sensor on a solar panel, an overlay plot comparing 
+the results of all temperature sensors, the command dictionary for a spacecraft,
+the individual commands in that dictionary, the "My Items" folder:
 All of these things are domain objects.

-Domain objects have Types, so a specific instrument temperature sensor is a
-"Telemetry Point," and turning on a drill for a certain duration of time is
-an "Activity".  Types allow you to form an ontology of knowledge and provide
-an abstraction for grouping, visualizing, and interpreting data.
+A _Domain Object_ is simply a javascript object with some standard attributes.  
+An example of a _Domain Object_ is the "My Items" object which is a folder in 
+which a user can persist any objects that they create. The My Items object 
+looks like this: 

-And then we have Views. Views allow you to visualize domain objects. Views can
-apply to specific domain objects; they may also apply to certain types of
-domain objects, or they may apply to everything.  Views are simply a method
-of visualizing domain objects.
-
-Regions allow you to specify what views are displayed for specific types of
-domain objects in response to different user actions. For instance, you may
-want to display a different view while editing, or you may want to update the
-toolbar display when objects are selected.  Regions allow you to map views to
-specific user actions.
-
-Domain objects can be mutated and persisted, developers can create custom
-actions and apply them to domain objects, and many more things can be done.
-For more information, read on!
-
-## Running Open MCT
-
-Once the [`openmct`](@link module:openmct) module has been loaded, you can
-simply invoke [`start`]{@link module:openmct.MCT#start} to run Open MCT:
-
-
-```
-openmct.start();
+```javascript
+{
+    identifier: {
+        namespace: ""
+        key: "mine"
+    }
+    name:"My Items",
+    type:"folder",
+    location:"ROOT",
+    composition: []
+}
 ```

-Generally, however, you will want to configure Open MCT by adding plugins
-before starting it. It is important to install plugins and configure Open MCT
-_before_ calling [`start`]{@link module:openmct.MCT#start}; Open MCT is not
-designed to be reconfigured once started.
+### Object Attributes

-## Configuring Open MCT
+The main attributes to note are the `identifier`, and `type` attributes.
+* `identifier`: A composite key that provides a universally unique identifier for 
+this object. The `namespace` and `key` are used to identify the object. The `key` 
+must be unique within the namespace. 
+* `type`: All objects in Open MCT have a type. Types allow you to form an 
+ontology of knowledge and provide an abstraction for grouping, visualizing, and 
+interpreting data. Details on how to define a new object type are provided below. 

-The [`openmct`]{@link module:openmct} module (more specifically, the
-[`MCT`]{@link module:openmct.MCT} class, of which `openmct` is an instance)
-exposes a variety of methods to allow the application to be configured,
-extended, and customized before running.
+Open MCT uses a number of builtin types. Typically you are going to want to 
+define your own if extending Open MCT.

-Short examples follow; see the linked documentation for further details.
+### Domain Object Types

-### Adding Domain Object Types
+Custom types may be registered via the `addType` function on the opencmt Type 
+registry.

-Custom types may be registered via
-[`openmct.types`]{@link module:openmct.MCT#types}:
-
-```
+eg.
+```javascript
 openmct.types.addType('my-type', {
    label: "My Type",
    description: "This is a type that I added!",
@@ -78,64 +152,98 @@ openmct.types.addType('my-type', {
 });
 ```

-### Adding Views
+The `addType` function accepts two arguments:
+* A `string` key identifying the type. This key is used when specifying a type 
+for an object.
+* An object type specification. An object type definition supports the following 
+attributes      
+    * `label`: a `string` naming this object type
+    * `description`: a `string` specifying a longer-form description of this type
+    * `initialize`: a `function` which initializes the model for new domain objects 
+    of this type. This can be used for setting default values on an object when 
+    it is instantiated.
+    * `creatable`: A `boolean` indicating whether users should be allowed to create 
+    this type (default: `false`). This will determine whether the type appears 
+    in the `Create` menu.
+    * `cssClass`: A `string` specifying a CSS class to apply to each representation 
+    of this object. This is used for specifying an icon to appear next to each 
+    object of this type.

-Custom views may be registered based on the region in the application
-where they should appear:
+The [Open MCT Tutorials](https://github.com/openmct/openmct-tutorial) provide a 
+step-by-step examples of writing code for Open MCT that includes a [section on 
+defining a new object type](https://github.com/nasa/openmct-tutorial#step-3---providing-objects).

-* [`openmct.mainViews`]{@link module:openmct.MCT#mainViews} is a registry
-  of views of domain objects which should appear in the main viewing area.
-* [`openmct.inspectors`]{@link module:openmct.MCT#inspectors} is a registry
-  of views of domain objects and/or active selections, which should appear in
-  the Inspector.
-* [`openmct.toolbars`]{@link module:openmct.MCT#toolbars} is a registry
-  of views of domain objects and/or active selections, which should appear in
-  the toolbar area while editing.
-* [`openmct.indicators`]{@link module:openmct.MCT#inspectors} is a registry
-  of views which should appear in the status area of the application.
+## Root Objects

-Example:
+In many cases, you'd like a certain object (or a certain hierarchy of objects) 
+to be accessible from the top level of the application (the tree on the left-hand 
+side of Open MCT.) For example, it is typical to expose a telemetry dictionary 
+as a hierarchy of telemetry-providing domain objects in this fashion.

-```
-openmct.mainViews.addProvider({
-    canView: function (domainObject) {
-        return domainObject.type === 'my-type';
-    },
-    view: function (domainObject) {
-        return new MyView(domainObject);
-    }
-});
+To do so, use the `addRoot` method of the object API.
+
+eg.
+```javascript
+openmct.objects.addRoot({
+        namespace: "my-namespace",
+        key: "my-key"
+    });
 ```

-### Adding a Root-level Object
-
-In many cases, you'd like a certain object (or a certain hierarchy of
-objects) to be accessible from the top level of the application (the
-tree on the left-hand side of Open MCT.) It is typical to expose a telemetry
-dictionary as a hierarchy of telemetry-providing domain objects in this
-fashion.
-
-To do so, use the [`addRoot`]{@link module:openmct.ObjectAPI#addRoot} method
-of the [object API]{@link module:openmct.ObjectAPI}:
-
-```
-openmct.objects.addRoot({ key: "my-key", namespace: "my-namespace" });
-```
+The `addRoot` function takes a single [object identifier](#domain-objects-and-identifiers) 
+as an argument. 

 Root objects are loaded just like any other objects, i.e. via an object
 provider.

+## Object Providers
+
+An Object Provider is used to build _Domain Objects_, typically retrieved from 
+some source such as a persistence store or telemetry dictionary. In order to 
+integrate telemetry from a new source an object provider will need to be created 
+that can build objects representing telemetry points exposed by the telemetry 
+source. The API call to define a new object provider is fairly straightforward. 
+Here's a very simple example:
+
+```javascript
+openmct.objects.addProvider('example.namespace', {
+    get: function (identifier) {
+        return Promise.resolve({
+            identifier: identifier,
+            name: 'Example Object',
+            type: 'example-object-type'
+        });
+    }
+});
+```
+The `addProvider` function takes two arguments:
+
+* `namespace`: A `string` representing the namespace that this object provider 
+will provide objects for.
+* `provider`: An `object` with a single function, `get`. This function accepts an 
+[Identifier](#domain-objects-and-identifiers) for the object to be provided. 
+It is expected that the `get` function will return a 
+[Promise](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Promise) 
+that resolves with the object being requested.
+
+In future, object providers will support other methods to enable other operations 
+with persistence stores, such as creating, updating, and deleting objects.
+
+## Composition Providers
+
+The _composition_ of a domain object is the list of objects it contains, as shown 
+(for example) in the tree for browsing. Open MCT provides a
+[default solution](#default-composition-provider) for composition, but there
+may be cases where you want to provide the composition of a certain object
+(or type of object) dynamically.
+

 ```
+The `addProvider` function accepts a Composition Provider object as its sole 
+argument. A Composition Provider is a javascript object exposing two functions:
+* `appliesTo`: A `function` that accepts a `domainObject` argument, and returns 
+a `boolean` value indicating whether this composition provider applies to the 
+given object.
+* `load`: A `function` that accepts a `domainObject` as an argument, and returns
+a `Promise` that resolves with an array of [Identifier](#domain-objects-and-identifiers).
+These identifiers will be used to fetch Domain Objects from an [Object Provider](#object-provider)

-### Adding Telemetry Providers
+### Default Composition Provider

-When connecting to a new telemetry source, you will want to register a new
-[telemetry provider]{@link module:openmct.TelemetryAPI~TelemetryProvider}
-with the [telemetry API]{@link module:openmct.TelemetryAPI#addProvider}:
+The default composition provider applies to any domain object with a `composition` 
+property. The value of `composition` should be an array of identifiers, e.g.:

+```javascript
+var domainObject = {
+    name: "My Object",
+    type: 'folder',
+    composition: [
+        {
+            id: '412229c3-922c-444b-8624-736d85516247',
+            namespace: 'foo'
+        },
+        {
+            key: 'd6e0ce02-5b85-4e55-8006-a8a505b64c75',
+            namespace: 'foo'
+        }
+    ]
+};
 ```
+
+## Telemetry Providers
+
+When connecting to a new telemetry source, you will need to register a new
+_Telemetry Provider_. A _Telemetry Provider_ retrieves telemetry data from some telemetry 
+source, and exposes them in a way that can be used by Open MCT. A telemetry 
+provider typically can support a one off __request__ for a batch of telemetry data, 
+or it can provide the ability to __subscribe__ to receive new telemetry data when 
+it becomes available, or both.
+
+```javascript
 openmct.telemetry.addProvider({
-    canProvideTelemetry: function (domainObject) {
-        return domainObject.type === 'my-type';
+    supportsRequest: function (domainObject) {
+        //...
    },
-    properties: function (domainObject) {
-        return [
-            { key: 'value', name: "Temperature", units: "degC" },
-            { key: 'time', name: "UTC" }
-        ];
+    supportsSubscribe: function (domainObject) {
+        //...
    },
-    request: function (domainObject, options) {
-        var telemetryId = domainObject.myTelemetryId;
-        return myAdapter.request(telemetryId, options.start, options.end);
+    request: function (domainObject, options) {    
+        //...
    },
-    subscribe: function (domainObject, callback) {
-        var telemetryId = domainObject.myTelemetryId;
-        myAdapter.subscribe(telemetryId, callback);
-        return myAdapter.unsubscribe.bind(myAdapter, telemetryId, callback);
+    subscribe: function (domainObject, callback, options) {
+        //...
    }
-});
+})
 ```

+A telemetry provider is an object with the following functions defined:
+
+* `supportsRequest`: An __optional__ `function` that accepts a 
+[Domain Object](#domain-objects-and-identifiers) and returns a `boolean` value
+indicating whether or not this provider supports telemetry requests for the 
+given object. If this returns `true` then a `request` function must be defined. 
+* `supportsSubscribe`: An __optional__ `function` that accepts a 
+[Domain Object](#domain-objects-and-identifiers) and returns a `boolean` value 
+indicating whether or not this provider supports telemetry subscriptions. If this 
+returns `true` then a `subscribe` function must also be defined. As with `request`, 
+the return value will typically be conditional, and based on attributes of 
+`domainObject` such as its identifier.
+* `request`: A `function` that returns a `Promise` that will resolve with an `Array` 
+of telemetry in a single query. This function accepts as arguments a 
+[Domain Object](#domain-objects-and-identifiers) and an object containing some 
+[request options](#telemetry-requests). 
+* `subscribe`:  A `function` that accepts a [Domain Object](#domain-objects-and-identifiers),
+a callback `function`, and a [telemetry request](#telemetry-requests). The 
+callback is invoked whenever telemetry is available, and 
+
+
 The implementations for `request` and `subscribe` can vary depending on the
 nature of the endpoint which will provide telemetry. In the example above,
-it is assumed that `myAdapter` contains the specific implementations
-(HTTP requests, WebSocket connections, etc.) associated with some telemetry
+it is assumed that `myAdapter` contains the implementation details
+(such as HTTP requests, WebSocket connections, etc.) associated with some telemetry
 source.

-## Using Open MCT
+For a step-by-step guide to building a telemetry adapter, please see the 
+[Open MCT Tutorials](https://github.com/larkin/openmct-tutorial).

-When implementing new features, it is useful and sometimes necessary to
-utilize functionality exposed by Open MCT.
-
-### Retrieving Composition
-
-To limit which objects are loaded at any given time, the composition of
-a domain object must be requested asynchronously:
-
-```
-openmct.composition(myObject).load().then(function (childObjects) {
-    childObjects.forEach(doSomething);
-});
+### Telemetry Requests
+Telemetry requests support time bounded queries. A call to a _Telemetry Provider_'s 
+`request` function will include an `options` argument. These are simply javascript
+objects with attributes for the request parameters. An example of a telemetry 
+request object with a start and end time is included below:
+```javascript
+{
+    start: 1487981997240,
+    end: 1487982897240
+}
 ```

-### Support Common Gestures
+### Telemetry Data

-Custom views may also want to support common gestures using the
-[gesture API]{@link module:openmct.GestureAPI}. For instance, to make
-a view (or part of a view) selectable:
+Telemetry data is provided to Open MCT by _[Telemetry Providers](#telemetry-providers)_
+in the form of javascript objects. A collection of telemetry values (for example, 
+retrieved in response to a `request`) is represented by an `Array` of javascript 
+objects. These telemetry javascript objects are simply key value pairs.

-```
-openmct.gestures.selectable(myHtmlElement, myDomainObject);
+Typically a telemetry datum will have some timestamp associated with it. This 
+time stamp should have a key that corresponds to some time system supported by 
+Open MCT. If the `UTCTimeSystem` plugin is installed, then the key `utc` can be used.
+   
+An example of a telemetry provider request function that returns a collection of
+mock telemtry data is below:
+
+```javascript
+openmct.telemetry.addProvider({
+    supportsRequest: function (domainObject) {
+        return true
+    },
+    request: function (domainObject, options) {    
+        return Promise.resolve([
+            {
+                'utc': Date.now() - 2000,
+                'value': 1,
+            },
+            {
+                'utc': Date.now() - 1000,
+                'value': 2,
+            },
+            {
+                'utc': Date.now(),
+                'value': 3,
+            }
+        ]);
+    }
+})
 ```

-### Working with Domain Objects
+## Included Plugins

-The [object API]{@link module:openmct.ObjectAPI} provides useful methods
-for working with domain objects.
-
-To make changes to a domain object, use the
-[`mutate`]{@link module:openmct.ObjectAPI#mutate} method:
+Open MCT is packaged along with a few general-purpose plugins:

+* `openmct.plugins.CouchDB` is an adapter for using CouchDB for persistence
+  of user-created objects. This is a constructor that takes the URL for the
+  CouchDB database as a parameter, e.g.
+```javascript
+openmct.install(openmct.plugins.CouchDB('http://localhost:5984/openmct'))
 ```
-openmct.objects.mutate(myDomainObject, "name", "New name!");
+* `openmct.plugins.Elasticsearch` is an adapter for using Elasticsearch for
+  persistence of user-created objects. This is a
+  constructor that takes the URL for the Elasticsearch instance as a
+  parameter. eg.
+```javascript
+openmct.install(openmct.plugins.CouchDB('http://localhost:9200'))
 ```
+* `openmct.plugins.Espresso` and `openmct.plugins.Snow` are two different
+  themes (dark and light) available for Open MCT. Note that at least one
+  of these themes must be installed for Open MCT to appear correctly.
+* `openmct.plugins.LocalStorage` provides persistence of user-created
+  objects in browser-local storage. This is particularly useful in
+  development environments.
+* `openmct.plugins.MyItems` adds a top-level folder named "My Items"
+  when the application is first started, providing a place for a
+  user to store created items.
+* `openmct.plugins.UTCTimeSystem` provides a default time system for Open MCT.

-Making modifications in this fashion allows other usages of the domain
-object to remain up to date using the
-[`observe`]{@link module:openmct.ObjectAPI#observe} method:
+Generally, you will want to either install these plugins, or install
+different plugins that provide persistence and an initial folder
+hierarchy.

+eg.
+```javascript
+openmct.install(openmct.plugins.LocalStorage());
+openmct.install(openmct.plugins.MyItems());
 ```
-openmct.objects.observe(myDomainObject, "name", function (newName) {
-    myLabel.textContent = newName;
-});
-```
-
-### Using Telemetry
-
-Very often in Open MCT, you wish to work with telemetry data (for instance,
-to display it in a custom visualization.)

-Views which wish to remain synchronized with the state of Open MCT's
-time conductor should utilize
-[`openmct.conductor`]{@link module:openmct.TimeConductor}:
-
-```
-openmct.conductor.on('bounds', function (newBounds) {
-    requestTelemetry(newBounds.start, newBounds.end).then(displayTelemetry);
-});
-```
-
-## Plugins
-
-While you can register new features with Open MCT directly, it is generally
-more useful to package these as a plugin. A plugin is a function that takes
-[`openmct`]{@link module:openmct} as an argument, and performs configuration
-upon `openmct` when invoked.
-
-### Installing Plugins
-
-To install plugins, use the [`install`]{@link module:openmct.MCT#install}
-method:
-
-```
-openmct.install(myPlugin);
-```
-
-The plugin will be invoked to configure Open MCT before it is started.
-
-### Writing Plugins
-
-Plugins configure Open MCT, and should utilize the
-[`openmct`]{@link module:openmct} module to do so, as summarized above in
-"Configuring Open MCT" and "Using Open MCT" above.
-
-### Distributing Plugins
-
-Hosting or downloading plugins is outside of the scope of this documentation.
-We recommend distributing plugins as UMD modules which export a single
-function.

 Open MCT defines several Angular directives that are intended for use both 
 internally within the platform, and by plugins. 
-
-## Before Unload 
-
-The `mct-before-unload` directive is used to listen for (and prompt for user 
-confirmation) of navigation changes in the browser. This includes reloading, 
-following links out of Open MCT, or changing routes. It is used to hook into 
-both `onbeforeunload` event handling as well as route changes from within 
-Angular.
-
-This directive is useable as an attribute. Its value should be an Angular 
-expression. When an action that would trigger an unload and/or route change 
-occurs, this Angular expression is evaluated. Its result should be a message to 
-display to the user to confirm their navigation change; if this expression 
-evaluates to a falsy value, no message will be displayed. 
- 
-## Chart 
-
-The `mct-chart` directive is used to support drawing of simple charts. It is 
-present to support the Plot view, and its functionality is limited to the 
-functionality that is relevant for that view.
-
-This directive is used at the element level and takes one attribute, `draw` 
-which is an Angular expression which will should evaluate to a drawing object. 
-This drawing object should contain the following properties:
-
-* `dimensions`: The size, in logical coordinates, of the chart area. A 
-two-element array or numbers. 
-* `origin`: The position, in logical coordinates, of the lower-left corner of 
-the chart area. A two-element array or numbers. 
-* `lines`: An array of lines (e.g. as a plot line) to draw, where each line is 
-expressed as an object containing: 
-    * `buffer`: A Float32Array containing points in the line, in logical 
-    coordinates, in sequential x,y pairs. 
-    * `color`: The color of the line, as a four-element RGBA array, where 
-    each element is a number in the range of 0.0-1.0. 
-    * `points`: The number of points in the line. 
-* `boxes`: An array of rectangles to draw in the chart area. Each is an object 
-containing: 
-    * `start`: The first corner of the rectangle, as a two-element array of 
-    numbers, in logical coordinates. 
-    * `end`: The opposite corner of the rectangle, as a two-element array of 
-    numbers, in logical coordinates. color : The color of the line, as a 
-    four-element RGBA array, where each element is a number in the range of 
-    0.0-1.0. 
-
-While `mct-chart` is intended to support plots specifically, it does perform 
-some useful management of canvas objects (e.g. choosing between WebGL and Canvas 
-2D APIs for drawing based on browser support) so its usage is recommended when 
-its supported drawing primitives are sufficient for other charting tasks.

 # Extensions

-## Directives
-
-This bundle introduces the `mct-before-unload` directive, primarily for
-internal use (to prompt the user to confirm navigation away from unsaved
-changes in Edit mode.)
-
-The `mct-before-unload` directive is used as an attribute whose value is
-an Angular expression that is evaluated when navigation changes (either
-via browser-level changes, such as the refresh button, or changes to
-the Angular route, which happens when hitting the back button in Edit
-mode.) The result of this evaluation, when truthy, is shown in a browser
-dialog to allow the user to confirm navigation. When falsy, no prompt is
-shown, allowing these dialogs to be shown conditionally. (For instance, in
-Edit mode, prompts are only shown if user-initiated changes have
-occurred.)
-
-This directive may be attached to any element; its behavior will be enforced
-so long as that element remains within the DOM.
-
