Re: [OAUTH-WG] Proposed URN for JWT token type: urn:ietf:params:oauth:token-type:jwt
I understand what you're saying, but I still believe that the URN is the correct one. While I agree that the potential for confusion is unfortunate, context will actually successfully differentiate the two uses of similar terms. 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:bcampb...@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.

[OAUTH-WG] Proposed URN for JWT token type: urn:ietf:params:oauth:token-type:jwt
I'm editing the JWT spec to prepare for the OAuth WG version and to track changes in the JOSE specs. Currently the "typ" values defined for JWT tokens are "JWT" and "http://openid.net/specs/jwt/1.0"; (see http://tools.ietf.org/html/draft-jones-json-web-token-08#section-5). I believe that the URN value should be changed to use a URN taken from the OAuth URN namespace urn:ietf:params:oauth (defined in http://tools.ietf.org/html/draft-ietf-oauth-urn-sub-ns-02). I propose to use the URN: urn:ietf:params:oauth:token-type:jwt I believe this fits well with the other four uses of this namespace to date: urn:ietf:params:oauth:grant-type:saml2-bearer urn:ietf:params:oauth:client-assertion-type:saml2-bearer urn:ietf:params:oauth:grant-type:jwt-bearer urn:ietf:params:oauth:client-assertion-type:jwt-bearer (The first two are from http://tools.ietf.org/html/draft-ietf-oauth-saml2-bearer-11. The latter two are from http://tools.ietf.org/html/draft-jones-oauth-jwt-bearer-04.) Do people agree with this URN choice?

A New Internet-Draft is available from the on-line Internet-Drafts directories. This draft is a work item of the Web Authorization Protocol Working Group of the IETF. Title : The OAuth 2.0 Authorization Framework Author(s) : Eran Hammer David Recordon Dick Hardt Filename: draft-ietf-oauth-v2-26.txt Pages : 66 Date: 2012-05-01 The OAuth 2.0 authorization framework enables a third-party application to obtain limited access to an HTTP service, either on behalf of a resource owner by orchestrating an approval interaction between the resource owner and the HTTP service, or by allowing the third-party application to obtain access on its own behalf. This specification replaces and obsoletes the OAuth 1.0 protocol described in RFC 5849.
