Re: [OAUTH-WG] I-D Action: draft-ietf-oauth-rar-04.txt

[Francis Pouatcha <[e-mail]>]

Find bellow my review of the draft:


  1.  Redactional changes:

2.2.  Authorization Data Types


Interpretation of the value of the "type" parameter, and the object

   elements that the "type" parameter allows => allowed


9.  Metadata

which is an

   JSON array. => which is a JSON array



  1.  Application to existing APIs

reason-1: Current open banking initiatives are built on the of existing Data Standards like ISO20022 (PAIN, CAMT) which are XML's that do not provide direct translation to JSON. Some authorization server's might even be able to parse an ISO PAIN file to display the proper authorization request to the user.

reason-2: In some situation, it might be more privacy preserving to have the authorization request content negotiated between the AS and the RS. In this case the "scope" parameter shall only carry some sort of "grant-id" (known in the Berlin Group spec as consent-id). This will allow the AS to negotiate the data to be displayed directly with the RS.

Any idea how to consider these two edge cases?

Best regards.
/Francis
