Security OAuth Working Group OAuth URN sub-namespace urn:ietf:params:oauth This document establishes an IETF URN Sub-namespace for use with OAuth related specifications.

Various extensions and companion specifications to The OAuth 2.0 Authorization Framework 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, for use with such specifications. The new 'oauth' sub-namespace is urn:ietf:params:oauth and OAuth relevant parameters will be established underneath it.

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. The URI that identifies the registered functionality. The name by which the functionality being registered is generally known. 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. 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 of this document.

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. 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. URN: urn:ietf:params:oauth:grant-type:example Common Name: An Example Grant Type for OAuth 2.0 Change controller: IETF Specification Document: [[the document URI]]

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. Any work that is related to OAuth would benefit from familiarity with the security considerations of The OAuth 2.0 Authorization Framework.

This document makes two requests of IANA: Registration of a new IANA URN sub-namespace, urn:ietf:params:oauth:, per RFC 3553. The registration request can be found in below. 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 .

Per RFC 3553, IANA is requested to please register a new URN sub-namespace, urn:ietf:params:oauth. Registry name: oauth Specification: [[this document]] Repository: [[The registry created in Section 3.]] 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.
