1. Introduction
Various extensions and companion specifications to the OAuth 2.0
Authorization Framework [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 an 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, email address, and home page URI) may also
be included.
Campbell & Tschofenig Informational [Page 2]RFC 6755 An IETF URN Sub-Namespace for OAuth October 2012
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 of this
document (Section 4).
2.1. Example Registration Request
The following is an example registration request for a URI underneath
the urn:ietf:params:oauth Sub-namespace. 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.
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 [RFC2141].
Any work that is related to OAuth would benefit from familiarity with
the security considerations of the OAuth 2.0 Authorization Framework
[OAUTH-V2].
4. IANA Considerations
IANA has created the following:
o The registration of a new IANA URN Sub-namespace,
urn:ietf:params:oauth:, per RFC 3553 [RFC3553]. The registration
request can be found in Section 4.1 below.
o A new registry called the "OAuth URI" registry for URNs
subordinate to urn:ietf:params:oauth. The registry "OAuth URI"
has been added to a new top-level registry called "OAuth
Campbell & Tschofenig Informational [Page 3]RFC 6755 An IETF URN Sub-Namespace for OAuth October 2012
Parameters" as defined by [OAUTH-V2]. 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 RFC 3553 [RFC3553], IANA has registered a new URN Sub-namespace,
urn:ietf:params:oauth.
o Registry name: oauth
o Specification: [this document]
o Repository: [The registry created in Section 2.]
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.
