Scenario: Obtain the AM Resource URI via Picker

In this scenario a client uses the AM service provider resource picker URI to search for and select an AM resource URI. This scenario involves the delegated resource selection specification.

This scenario requires that the client has already discovered the Simple Query URI via the service catalog.

Example 1: Web client selects an AM resource

1. The client obtains the URI of the resource picker from the discovery documents ( https://am.acme.com/picker/project1).

2. The client presents a graphical window to the user. This may be a web browser or a desktop application UI. Inside this window the client creates an HTML frame to render the picker in. The client creates listeners on the HTML frame.

3. The client displays the results of a GET on the resource picker URI (if required authentication, BASIC or OAuth is negotiated, and may require an additional HTML form to log in with). After authentication the HTML frame renders the resource picker.

When the user selects a resource, java script function is invoked and the URI of the selected resource an event is --> </html>

GET https://am.acme.com/picker/project1
Accept: application/atom+xml

Response

200 OK
Content-Type: text/html

<html>

  <script>

     function postMessageProtocol(/*string*/ url) { ... }
     function windowNameProtocol(/*string*/ url, onDataReceived) {...}

  </script>


  <!-- 
       some HTML and Java script, that renders an HTML form 
       that the user interacts with to search for an architecture
       resource.  When the user selects a resource, java script
       function is invoked and the URI of the selected resource
       an event is
  -->

</html>

4. The interacts with the HTML page, which uses Java Script to talk back to the service provider and provide lists of results based on search criteria for the user to choose from.

5. The user selects a resource. The java script in the HTML sends up an event with the selected resource's URI to the client window.

6. The client window receives the event, records the resource URI, and closes the HTML frame and maybe the window.
