Liberty Alliance defined:
Liberty's Identity Web Services Framework (IDWSF), a platform for securing identity-based web services, continues to evolve within the Liberty Alliance. Liberty ID-WSF uses SAML assertions as the security token format by which the authentication and authorization information associated with the various web service actors are communicated amongst them.
