             User-Managed Access (UMA) Profile of OAuth 2.0
                    draft-hardjono-oauth-umacore-13

Abstract

   User-Managed Access (UMA) is a profile of OAuth 2.0.  UMA defines how
   resource owners can control protected-resource access by clients
   operated by arbitrary requesting parties, where the resources reside
   on any number of resource servers, and where a centralized
   authorization server governs access based on resource owner policies.
