**Canonical:** https://apis.io/apis/rice/incommon-federation/

InCommon Federation registration is one of 8 APIs that [Rice University](https://apis.io/providers/rice/) publishes on the [APIs.io](https://apis.io/) network. Tagged areas include Identity Federation, InCommon, SAML, Metadata, and Higher Education. The published artifact set on APIs.io includes API documentation.

Rice's identity provider is registered in InCommon, the US research and education identity federation, and InCommon's metadata query service returns a signed EntityDescriptor for entityID https://idp.rice.edu/idp/shibboleth with registrationAuthority https://incommon.org. A federation is shared by definition; the entity inside it is Rice's, and this membership is what makes Rice's IdP usable by every other InCommon participant. Recorded as a relationship, never as Rice's contract.
