I agree that context does sufficiently differentiate. I guess I'm just lamenting the way that type has been overloaded in the base OAuth stuff and am already dreading the conversions that might go something like, "well which type of token type are we talking about here?" This particular URN probably doesn't change that one way or the other and I'm okay with what you've proposed. I just felt compelled to mention the potential confusion point.

Bear in mind that the OAuth usage of the term is actually short for "Access Token Type" (see OAuth Core sections 8.1 and 11.1), whereas the URN above is to provide a type identifier for a particular kind of security token. > > I also believe that the examples in the Bearer spec (see http://tools.ietf.org/html/draft-ietf-oauth-v2-bearer-19#section-4), the MAC spec (see http://tools.ietf.org/html/draft-ietf-oauth-v2-http-mac-01#section-5.1), and the JWT spec will make the uses of these terms clear to implementers in context. > > -- Mike > > -----Original Message----- > From: Brian Campbell [mailto:bcampbell@pingidentity.com] > Sent: Tuesday, May 01, 2012 4:26 PM > To: Mike Jones > Cc: oauth@ietf.org > Subject: Re: [OAUTH-WG] Proposed URN for JWT token type: urn:ietf:params:oauth:token-type:jwt > > The only concern I might raise with it is that use of the "token-type" > part might lead to some confusion. The term token type and the parameter token_type are already pretty loaded and have specific meaning from the core OAuth framework: > http://tools.ietf.org/html/draft-ietf-oauth-v2-26#section-7.1 > > That token type is about providing "the client with the information required to successfully utilize the access token to make a protected resource request" (i.e. mac and bearer) and is not about the structure of the token itself which is what this URI seems to want to describe. > JWTs are usually thought of as bearer type tokens but might someday have HoK (http://lists.openid.net/pipermail/openid-specs-ab/Week-of-Mon-20120430/001860.html) > or mac like constructs. > > I don't think there's really a problem with name collisions here but I think that the current use of token type in the frame work spec is already the cause of some confusion and I'd hate to exacerbate that. > > On Tue, May 1, 2012 at 5:04 PM, Mike Jones <Michael.Jones@microsoft.com> wrote: >> I'm editing the JWT spec to prepare for the OAuth WG version and to >> track changes in the JOSE specs.
