R&S is used in the eduGAIN interfederation to make services available to users of the higher education institution around the world. The R&S makes it possible to automatically release mostly harmless attributes to Service Providers within the higher educational sector. The expected IdP behaviour is to release the Service Provider required subset Provider set of the R&S Category Attributes (eptid, eppn, email, displayName, surname, given name and scoped affiliation). The requested subset of attributes for a specific service is defined in metadata. There is furthermore an identity provider entity support category that should be registered for all IdP that supports the R&S Category that can be used for filter purpose in a discovery service.
