Technical Summary
The "OAuth 2.0 Token Introspection" specification defines a method
for a protected resource to query an OAuth 2.0 authorization server
to determine the active state of an OAuth 2.0 token and to determine
meta-information about this token. OAuth 2.0 deployments can use
this method to convey information about the authorization context
of the token from the authorization server to the protected resource.
Working Group Summary
There was no controversy. When the specification was brought
to the working group the concept was already well established and
in use.
Document Quality
There are multiple implementations of this specification,
with links included in the shepherd writeup.
Personnel
Hannes Tschofenig is the document shepherd and Kathleen Moriarty is
the responsible area director.
IANA Note
The IANA consideration section defines a new registry, called
"OAuth Token Introspection Response Registry", and populates this
registry with 12 values. Additional entries may be added with a
Specification Required ([RFC5226]) and Designated Expert review on
the oauth-ext-review@ietf.org mailing list.
