Want to know if collaborative work on User-Managed Access is for you? Check out the group's charter document! The next phase of our efforts involves four prongs: 1) spec enhancements (such as extensions); 2) business model (aka "UMA Legal") work; 3) promoting adoption; and 4) promoting interop. If any of these could accelerate your own efforts, join us!

Many resources to understand more about UMA are available. Don't miss the slides and video from Authorization: Age of UMA, the "Introducing UMA 2.0" session delivered by two UMA coauthors at the Chicago Cloud Identity Summit. The Release Notes are up to date with all spec changes through the first Public Comment period. See also the UMA Implementer's Guide, our list of known Implementations, and discussions of Case Studies, all of which continue to grow. Finally, see the UMA Grant sequence diagram and FedAuthz sequence diagram.
