Hi Eran,
http://oauth.net/grant_type/saml/2.0/bearer is definitely not a good idea since
a lookup would not return anything useful (most likely it will just fail).
Whenever there is something that can be looked up, it will be looked up .
I would create an IETF URN Sub-namespace, as documented in RFC 3553. An example
of such a sub-namespace is xml and described in RFC 3688.
So, one could define a new 'oauth' sub-namespace. This would then look like
urn:ietf:params:oauth. Then, OAuth relevant parameters would be established
underneath it.
To get this done three things are needed:
1) Text that requests the oauth sub-namespace text
This text has to go into draft-ietf-oauth-v2.
2) Text that defines how values are added to this new registry
This text has to go into draft-ietf-oauth-v2.
3) Text that registers already defined values.
This text would go into draft-ietf-oauth-saml2-bearer following the template
created with (2).
Regarding (1), example text could look like:
---------
IETF URN Sub-namespace Registration urn:ietf:params:oauth
Per [RFC3553], IANA is requested to establish the following registry. New
entries
to the registry are Specification Required.
Registry name: urn:ietf:params:oauth
Specification: Section X of this document contains the registry
specification.
Repository: To be assigned according to the guidelines found above.
Index value: The class name
---------
Regarding (2), example text could look like:
---------
Section X: Registration Template for Sub-Namspace Registration of
urn:ietf:params:oauth
If the registrant wishes to
have a URI assigned, then a URN of the form
urn:ietf:params:oauth:<class>:<id>
will be assigned where <class> is the category of the parameters being
registered. <id> is a unique id generated by the IANA
based on any means the IANA deems necessary to maintain uniqueness
and persistence. NOTE: in order for a URN of this type to be
assigned, the item being registered MUST be documented
in a RFC. The RFC 3553 [RFC3553] URN registration template is found
in the IANA consideration section of this document.
The registration procedure for new entries to the requires a request in the
form of the following template:
URN:
The token URI that identifies the registerd component. If
the registrant is requesting that the IANA assign a URI then this
field should be specified as "please assign".
Common Name:
The name by which the functionality being registered is generally
referred.
Registrant Contact:
The individual/organization that is the registration contact for
the component being registered. Ideally, this will be the name
and pertinent physical and network contact information. In the
case of IETF developed standards, the Registrant will be the IESG.
Description:
Information about the registered functionality.
---------
Regarding (3), example text could look like:
---------
Sub-Namspace Registration of urn:ietf:params:oauth:grant-type:saml2-bearer
This is a request to IANA to please register the value grant-type:saml2-bearer
in the registry urn:ietf:params:oauth established in [draft-ietf-oauth-v2].
URN: urn:ietf:params:oauth:grant-type:saml2-bearer
Common Name: SAML 2.0 Bearer Assertion Grant Type Profile for OAuth 2.0
Registrant Contact: IESG
Description: [[this document]]
---------
Other grant types would then go in
urn:ietf:params:oauth:grant-type:saml2-holder-of-the-key
Other OAuth related parameters then go under urn:ietf:params:oauth:foobar
Ciao
