OAuth logoAaron Parecki and I published a new version the “OAuth 2.0 Protected Resource Metadata” specification that addresses the review comments received since the IETF Last Call. Per the history entries, the changes were:

  • Added metadata values declaring support for DPoP and mutual-TLS client certificate-bound access tokens.
  • Added missing word caught during IANA review.
  • Addressed ART, SecDir, and OpsDir review comments by Arnt Gulbrandsen, David Mandelberg, and Bo Wu, resulting in the following changes:
  • Added step numbers to sequence diagram.
  • Defined meaning of omitting bearer_methods_supported metadata parameter.
  • Added internationalization of human-readable metadata values using the mechanism from [RFC7591].
  • Added resource_name metadata parameter, paralleling client_name in [RFC7591].
  • Added Security Considerations section on metadata caching.
  • Used and referenced Resource Identifier definition.
  • Added motivating example of an email client to intro.
