Persistent

Full Title or Meme

When an entity has a Persistent Identifier the assumption is that the Behavior of the entity will remain consistent over time.

Problem

Many protocols, like OpenID Connect supply a Subject Identifier (sid) that is meant to reflect the same Subject over a period of time. Typically those protocols permit transitory binding of the Identifier to a real world entity. There appears to be no way to evaluate if the Identifier is meant to be Persistent from one connection to another.
