We had a presentation from Alex Ziegler about Riena at the RCP Experience Workshop which was well-received by everybody at the workshop. Alex is the project lead and lead architect of the proposed project. The Riena proposal includes an authorization and authentication mechanism that’s intended for communication between client and server. We discussed potentially leveraging this work as part of an extension to the expressions framework I mentioned in my previous post.
I think that one of the bigger challenges that will be faced by this project is containing its scope.
