Service Provider and Service Provider Resource

Enterprise Architect acts as an OSLC Provider that other OSLC-compliant tools (OSLC Consumer/Clients) access to link to its Resources. All OSLC Resources live in a Service Provider, which is a central organising concept of OSLC. In Enterprise Architect, each model that can be accessed via the Cloud connection is treated as an OSLC Service Provider. The Requirement elements in the model are the OSLC Resources.

The services offered by the Service Provider can be retrieved using the Service Provider Resource. A Service Provider Resource specifies the:

URL to which you can POST representations to create new resources
URL you can use to GET a list of existing resources
 

To retrieve the Service Provider Resource from an Enterprise Architect model connected via the Cloud, use the URL:

 http://<server>/<model_name>/oslc/sp/

 
For example, the Service Provider Resource for a model called firebird_model, connected via the Cloud, would be accessed using the URL:

  http://localhost:480/firebird_model/oslc/sp/

 
This retrieved resource would resemble this:
