Scenario: Find All Resources with any relationship to a given URI.

In this scenario the client wants to find all the AM resources that have a any kind of relationship to a known resource URI ( <http://rm.acme.com/requirements/req123>).

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

Example 1. Find all resources that elaborate a requirement

Starting with Simple Query? URI the client constructs a simple query and GET the resulting ATOM collection. In the place of the property id, a wildcard (*) is used to indicate that we are interested in any type of link.

The query before encoding is 

...?query=*=http://rm.acme.com/requirements/req123

A URL encoding it becomes 

..?query=*%3Dhttp%3A%2F%2Frm.acme.com%2Frequirements%2Freq123

Request (request URI line wraps to make more readable) 
GET https://am.acme.com/simplequery/project1?query=*%3Dhttp%3A%2F%2Frm.acme.com%2Frequirements%2Freq123
Accept: application/atom+xml
Response 
200 OK
Content-Type: application/atom+xml
