The UMA V1.0 specs are Kantara Initiative Recommendations


The UMA V1.0 specifications have been approved as Kantara Initiative Recommendations!

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, check out the implementations, test your interop, get involved!
