Technical Summary

   The OAuth 2.0 authorization framework [RFC6749] defines the parameter
   scope that allows OAuth clients to specify the requested scope, i.e.,
   the permission, of an access token.  This mechanism is sufficient to
   implement static scenarios and coarse-grained authorization requests,
   such as "give me read access to the resource owner's profile" but it
   is not sufficient to specify fine-grained authorization requirements,
   such as "please let me transfer an amount of 45 Euros to Merchant A"
   or "please give me read access to folder A and write access to file
   X".

   This specification introduces a new parameter authorization_details
   that allows clients to specify their fine-grained authorization
   requirements using the expressiveness of JSON data structures.

Working Group Summary

There were no controversial discussions related to this document.  A few key changes were made based on GENART review. 

Document Quality

There are several implementations and deployments of this specification
available, such as - the Yes banking ecosystem (with ~1200 IDPs) uses RAR for
authorising payment initiation and qualified electronic signatures. - ConnectID
product implementation, see
https://connect2id.com/products/server/docs/datasheet#rar - Authlete supports
RAR since version 2.2 and it is confirmed that at least one of their customers
is operating a commercial service that utilizes RAR with CIBA as of April, 2022.

Additionally, other organizations use this specification as a foundation for
their work. For example: - The Cloud Signature Consortium included RAR as means
to authorise electronic signature to the v 2.0 of its API for remote signature
creation (https://cloudsignatureconsortium.org/resources/
<https://cloudsignatureconsortium.org/resources/>). - OpenID Foundation’s FAPI
working group added RAR support to the FAPI 2 baseline profile
(https://openid.net/specs/fapi-2_0-baseline-01.html
<https://openid.net/specs/fapi-2_0-baseline-01.html>).
