The OSLC Core 2.0 specification defines two types of resources (discovery documents) that clients can use to determine server capabilities. The catalog resource provides a listing of specific service providers. In Design Management these correspond to individual DM projects. Each DM project is an OSLC AM and RM service provider. The catalog document lists these and provides references to specific service provider documents.
The service provider document provides specific service end points like resource pickers, and query services.
This service provides both types of documents depending on the segments in the URI.
