[DG-BSC] User-centric identity materials

HIE of One combines self-sovereign identifiers, verifiable claims, and
self-sovereign UMA AS. The self-sovereign components complement each other
and avoid introducing federation constraints typical to an IDP. Verifiable
claims are the non-self-sovereign component but that doesn't mean
federation as I use the term. Verifiable claims make the system

I'm not sure why we're choosing to compare Sovrin to anything. uPort,
blockstack, and Sovrin can all be used as self-sovereign identifiers under
the evolving DID spec

Why not start with the DID spec and verifiable claims as the basis and
compare them+UMA to OIDC+UMA? In HIE of One, we use both because I don't
see any reason to choose.

When you mention "other entities" in your example, I have trouble mapping
that into UMA. Can you elaborate?
