This proposal puts UMA's core protocol on a WRAP/hostmeta footing. Although it currently calls out to the WRAP I-D, the intent is to work with the IETF group working on OAuth 2.0 to ensure that it will meet our needs, either by allowing our needed extension and profiling points, or by incorporating solutions we have invented out of that are of interest to others as well.
This document currently assumes that the reader is intimately familiar with the WRAP I-D, but it will gain many more examples and more explanation/context.
