Although the root services document is not part of the OSLC specification, it provides the entry point for the OSLC service discovery documents and the configuration URLs that are needed to consume OSLC services.
Security is required for OSLC and is provided by OAuth 1.0a. OAuth is an open protocol that provides secure API authorization in a simple, standard method from desktop and web applications. To access most OSLC URIs, including URIs for service discovery, requirements, requirement collections, you must be an authenticated user. OAuth authentication is not required for the root services URI. For more information, see the OAuth 1.0a Specification.
