XRDS - Service Endpoints (SEPs)

Service Endpoints (SEPs)

The other main purpose of XRDS documents is to assert the services associated with a resource, called service endpoints or SEPs. For instance, the example XRDS document above asserts four service endpoints for the represented resource:

1. An XRI resolution service (type xri://$res*auth*($v*2.0)).
2. An OpenID 2.0 authentication service (type http://openid.net/signon/2.0).
3. An OpenID 1.0 authentication service (type http://openid.net/server/1.0).
4. An untyped service for requesting resources with a media type image/jpeg.

For full details of XRDS service endpoints, see XRI Resolution 2.0, Sections 4.2 and 13.
