titleInterop testing plans

We're working on feature tests at the UMA interop site, kindly hosted by the OSIS folks. Head over to to see and contribute to the progress, and to register your solution.


The purpose of the UMA Work Group (charter) is to develop specs that let an individual control the authorization of data sharing and service access made between online services on the individual's behalf, and to facilitate interoperable implementations of the specs. Read the spec, join the group, get involved!

Follow us on Twitter – our handle is @UMAWG and we often use the hashtag #UMAWG. (Short link for this page is – spread the word.) Find us on Facebook too.
