Internet-Draft Link Type Registrations for OAuth 2 October 2012
1. Introduction
This document defines the link type [RFC5988] registrations for the
OAuth 2 [I-D.ietf-oauth-v2] authentication framework. It also
defines link type registrations for OAuth 1.0a [RFC5849]. These link
types are used during the endpoint discovery process using Web Host
Metadata [RFC6415] and Webfinger [I-D.ietf-appsawg-webfinger] by
clients needing to discover the authorization, token, and initiation
endpoints for a service or site.

2. Terminology
The key words "MUST", "MUST NOT", "REQUIRED", "SHALL", "SHALL NOT",
"SHOULD", "SHOULD NOT", "RECOMMENDED", "MAY", and "OPTIONAL" in this
document are to be interpreted as described in [RFC2119].
The reader is assumed to be familiar with the terms used in the OAuth
2.0 specification [I-D.ietf-oauth-v2].
In examples line breaks have been inserted for readability.
Note that the IMAP SASL specification requires base64 encoding
message, not this memo.

3. Security Considerations
This document is informational, defining values in existing
registries, and as such has no security properties to discuss.

4. IANA Considerations
4.1. Link Type Registration
Pursuant to [RFC5988] The following link type registrations [[will
be]] registered by mail to link-relations@ietf.org.
4.1.1. OAuth 2 Authorization Endpoint
o Relation Name: oauth2-authorize
o Description: An OAuth 2.0 authorization endpoint.
o Reference: [I-D.ietf-oauth-v2]
o Notes: This link type indicates an OAuth 2.0 authorization
endpoint that can be used for user authentication/authorization
for the endpoint providing the link.
o Application Data: [optional]
4.1.2. OAuth 2 Token Endpoint
o Relation Name: oauth2-token
o Description: The OAuth token endpoint used to get tokens for
access.
o Reference: [I-D.ietf-oauth-v2]
o Notes: The OAuth 2.0 token endpoint to be used for obtaining
tokens to access the endpoint providing the link.
o Application Data: This link type has two link-extensions:
grant-types: A space separated list of OAuth 2.0 grant types (see
section 4 of [I-D.ietf-oauth-v2]) that can be used at the token
endpoint to obtain a token. This is not an exclusive list, it
provides a hint to the application of what SHOULD be valid. A
token endpoint MAY support additional grant types not
advertised by a discovery service. The client MAY use this to
determine the grant types available for use.
token-types: A space separated list of OAuth 2.0 token types (see
section 7.1 of [I-D.ietf-oauth-v2]) that may be issued by the
token endpoint. It is possible for a token endpoint to issue
multiple tokens, and types may vary based on scope or other
factors. This is not an exclusive list, it provides a hint to

Internet-Draft Link Type Registrations for OAuth 2 October 2012
the application of what SHOULD be valid, and it MAY be used by
a client to determine if the client supports one or more of the
token type(s) available.
4.1.3. OAuth 1.0a Request Initiation Endpoint
o Relation Name: oauth-initiate
o Description: The OAuth 1.0a request initiation endpoint used to
get an access request.
o Reference: [RFC5849]
o Notes: The OAuth 1.0a endpoint used to initiate the sequence, this
temporary request is what the user approves to grant access to the
resource.
o Application Data:
4.1.4. OAuth 1.0a Authorization Endpoint
o Relation Name: oauth-authorize
o Description: The OAuth 1.0a authorization endpoint used to approve
an access request.
o Reference: [RFC5849]
o Notes:
o Application Data:
4.1.5. OAuth 1.0a Token Endpoint
o Relation Name: oauth-token
o Description: The OAuth 1.0a token endpoint used to exchange an
approved access request for a token.
o Reference: [RFC5849]
o Notes:
o Application Data:
