Introduction Various extensions and companion specifications to The OAuth 2.0 Authorization Framework [I-D.ietf-oauth-v2] utilize URIs to identify the extension in use or other relevant context. This document creates and registers an IETF URN Sub-namespace, as documented in RFC 3553 [RFC3553], for use with such specifications. The new 'oauth' sub-namespace is urn:ietf:params:oauth and OAuth relevant parameters will be established underneath it. 2. Registration Template If a registrant wishes to have a OAuth URI registered, then a URN of the form urn:ietf:params:oauth:<value> will be requested where <value> is a suitable representation of the functionality or concept being registered. The registration procedure for new entries requires a request in the form of the following template and is Specification Required per RFC 5226 [RFC5226]. URN: The URI that identifies the registered functionality. Common Name: The name by which the functionality being registered is generally known. Change Controller: For standards-track RFCs, state "IETF". For others, give the name of the responsible party. Other details (e.g., postal address, e-mail address, home page URI) may also be included. Specification Document(s): Reference to the document that specifies the URI, preferably including a URI that can be used to retrieve a copy of the document. An indication of the relevant sections may also be included, but is not required. The registration request for the urn:ietf:params:oauth URN Sub- namespace is found in the IANA Considerations (Section 4) section of this document. 2.1. Example Registration Request The following is an example registration request for a URI underneath the urn:ietf:params:oauth sub-namespece. The requested URI represents a new OAuth 2.0 grant type. Campbell & Tschofenig Expires January 17, 2013 [Page 3] Internet-Draft An IETF URN Sub-Namespace for OAuth July 2012 This is a request to IANA to please register the value "grant-type:example" in the registry urn:ietf:params:oauth established in An IETF URN Sub-Namespace for OAuth. o URN: urn:ietf:params:oauth:grant-type:example o Common Name: An Example Grant Type for OAuth 2.0 o Change controller: IETF o Specification Document: [[the document URI]] 3. Security Considerations There are no additional security considerations beyond those already inherent to using URNs. Security considerations for URNs in general can be found in RFC 2141 [RFC 2141]. Any work that is related to OAuth would benefit from familiarity with the security considerations of The OAuth 2.0 Authorization Framework [I-D.ietf-oauth-v2]. 4. IANA Considerations This document makes two requests of IANA: o Registration of a new IANA URN sub-namespace, urn:ietf:params:oauth:, per RFC3553 [RFC3553]. The registration request can be found in Section 4.1 below. o Establishment of a new registry for URNs subordinate to urn:ietf:params:oauth. Instructions for a registrant to request the registration of such a URN are in Section 2. 4.1. IETF URN Sub-namespace Registration urn:ietf:params:oauth Per RFC3553 [RFC3553], IANA is requested to please register a new URN sub-namespace, urn:ietf:params:oauth. o Registry name: oauth o Specification: [[this document]] o Repository: [[The registry created in Section 3.]] Campbell & Tschofenig Expires January 17, 2013 [Page 4] Internet-Draft An IETF URN Sub-Namespace for OAuth July 2012 o Index value: values subordinate to urn:ietf:params:oauth are of the form urn:ietf:params:oauth:<value> with <value> as the index value. It is suggested that <value> include both a "class" and an "identifier-within-class" component, with the two components being separated by a colon (":"); other compositions of the <value> may also be used. 5.
