Re: [OAUTH-WG] draft-richer-oauth-introspection-01 scope syntax

I got the same reading of the list as you, and I could go either way. I believe we absolutely must pick one or the other though.

If anyone has thoughts on the matter one way or the other, please speak up. The options are:

1) scopes are returned as a JSON array (current introspection text)
2) scopes are returned as a space-separated string (rfc6749 format for the "scope" parameter)

Has there been any thinking or movement as to whether the scopes syntax stands as is, or aligns with 6749?  Of the folks who chose to respond, it seemed like the position was split.

I should add that this is also a bit of an artifact of our implementation. Internally, we parse and store scopes as collections of discrete strings and process them that way. So serialization of that value naturally fell to a JSON list.

It's not meant to follow the same syntax. Instead, it's making use of the JSON object structure to avoid additional parsing of the values on the client side.

We could fairly easily define it as the same space-delimited string if enough people want to keep the scope format consistent.

That the scope syntax in draft-richer-oauth-introspection-01 is different than RFC 6749 Section 3.3, as in:

  "scope": ["read", "write", "dolphin"],

vs.

 scope = scope-token *( SP scope-token )
    scope-token = 1*( %x21 / %x23-5B / %x5D-7E )

Should introspection-01 follow the 6749 syntax for scopes?
