Scenario: Get Link Types

This scenario the client asks the service provider for a list of known or registered link types. The service provider does not define link types, those are defined externally. Rather, the service provider just provides a mechanism for registering a predicate URI with a short name and description, that can be used by clients to populate selection lists.

In this scenario the client wants to find all the AM resources that have a certain values for specific properties. This scenario requires that the client has already discovered the Link Type Service URI via the service catalog.

Example 1. Get Registered Link Types

The client has a URI reference to an AM link type service ( https://am.acme.com/linktypes/project1).

1.The client performs a GET on the link type service URI with an application/atom+xml accept header. The collection of registered link types is returned as an Atom collection..

Request 
GET https://am.acme.com/linktypes/project1
Accept: application/atom+xml
Response 
200 OK
Content-Type: application/atom+xml
