Re: [OAUTH-WG] OAuth Discovery

[John Bradley <[e-mail]>]

The methods could be the same but they should probably specified separately eg

introspection_endpoint_auth_methods_supported
If we overload them we will probably regret it later.

The OAuth Discovery spec removes the portions of OpenID Connect Discovery that are OpenID specific and adds metadata values for Revocation and Introspection endpoints.  It also maps OpenID concepts, such as OpenID Provider, Relying Party, End-User, and Issuer to their OAuth underpinnings, respectively Authorization Server, Client, Resource Owner, and the newly introduced Configuration Information Location.  Some identifiers with names that appear to be OpenID specific were retained for compatibility purposes; despite the reuse of these identifiers that appear to be OpenID specific, their usage in this specification is actually referring to general OAuth 2.0 features that are not
