I just published a new I-D on the hyperlinked oauth that I talked at IETF 85. Since it was pointed out that the “_links” member is actually holding metadata about the response, I named the document accordingly. It is fairly short, only 9 pages long. It is something to be discussed at the oauth wg list.
In this -00 draft, I have just written down what I bloged in the past. Defining some additional relationships such as the public key etc. may be useful as well.
A new version of I-D, draft-sakimura-oauth-meta-00.txt
has been successfully submitted by Nat Sakimura and posted to the
Title: JSON Metadata for OAuth Responses
Creation date: 2012-12-12
WG ID: Individual Submission
Number of pages: 9
This specification defines an extensible metadata member that may be
inserted into the OAuth 2.0 responses to assist the clients to
process those responses. It is expressed as a member called “_links”
that is inserted as the top level member in the responses. It will
allow the client to learn where the members in the response could be
used and how, etc. Since it is just a member, any client that does
not understand this extension should not break and work normally
while supporting clients can utilize the metadata to its advantage.
