Subject: Access token question

Hi,

Quick question regarding access token and scope.
I know that “scope” semantics is left to the application to define, but in 
general I would expect to include there some information about resource and 
method/operations allowed on that resource. Please correct me if any of this is 
not exact.

It was my understanding that “scope” (or more precisely the “scope” value) 
defined for the Client-AS request and response should be included in the access 
token as well. Checking in CWT, there is no such “scope” claim defined. “aud” 
claim is indeed defined for the CWT, but that should correspond to “aud” 
parameter in the ACE request/response. So where do I put the exact resource and 
operations in the access token?

What am I missing?

Francesca
