The Work Group has published a new set of drafts as of 27 April 2017 fully reflecting comments and discussion during the recent review period. If you're familiar with our "traditional" two-spec breakdown, try this new restructuring on for size: Introducing the UMA 2.0 Grant for OAuth 2.0 Authorization, nicknamed Grant (rev 02), and Federated Authorization for UMA 2.0, nicknamed FedAuthz (rev 02).
Here is a detailed swimlane diagram that dynamically tracks the drafts, and a high-level swimlane diagram that briefly summarizes the UMA2 flow. Expect release notes soon. The UMA Implementer's Guide is also growing. We are very keen to get your implementation feedback ASAP. The group plans to vote on starting the Public Comment period on May 12. If you're interested to contribute to the review, testing, and finalization of the Kantara Recommendation versions of these specifications over the coming few weeks, it's not too late! Fill out the Group Participation Agreement form to get going.
