If you are a member of the OpenID Foundation, you'll be able to
login and vote on the creation of this new working group after
this
14-day notice period. The vote thus will be from Wednesday
February 11th through Wednesday February 18th. All votes are held
in US Pacific Time.

Background Information
OpenID has always been focused on how to enable user-
authentication
within the browser. Over the last year, OAuth has been developed
to allow authorization either from within a browser, desktop
software, or mobile devices. Obviously there has been interest in
using OpenID and OAuth together allowing a user to share their
identity as well as grant a Relying Party access to an OAuth
protected resource in a single step. A small group of people have
been working on developing an extension to OpenID which makes this
possible in a collaborative fashion within
http://code.google.com/p/step2/
. This small project includes a draft spec and Open Source
implementations which the proposers would like to finalize within
the OpenID Foundation.
Working Group Name
OpenID OAuth Hybrid Working Group
Purpose
Produce a standard OpenID extension to the OpenID Authentication
protocol that provides a mechanism to embed an OAuth approval
request into an OpenID authentication request to permit combined
user approval. The extension addresses the use case where the
OpenID Provider and OAuth Service Provider are the same service.
To
provide good user experience, it is important to present a
combined
authentication and authorization screen for the two protocols.
Scope
The proposed work is as follows:
* Extend the OpenID authentication request/response and the
assertion verification mechanism, to embed an OAuth approval
request into an OpenID authentication request. Assuming the
OpenID
Provider and OAuth Service Provider are the same service.
* Insulation of each protocol from the other, both for backwards
compatibility as well as to enable OpenID and OAuth to evolve and
incorporate additional features without requiring reviews of the
combined usage. Especially, to allow future support for
unregistered OAuth consumers.
* Security analysis and best practices
Out of scope
* The OpenID extension does not define an unregistered OAuth
consumers mode, but instead ensures that such support would be
possible by protocol insulation. The unregistered consumers mode
should be defined separately in the OAuth specifications.
Anticipated Contributions
Finalize the OpenID OAuth Extension spec
(http://step2.googlecode.com/svn/spec/openid_oauth_extension/drafts/0/openid_oauth_extension.html
) as an official OpenID Extension.
Proposed List of Specifications
OpenID OAuth Extension 1.0. Specification completion by Q1 2009.
Anticipated audience or users of the work
* OpenID Providers and Relying Parties
* OAuth Consumers and Service Providers
* Implementers of OpenID Providers and Relying Parties
Language in which the WG will conduct business
English.
Method of work
E-mail discussions on the working group mailing list and working
group conference calls.
Basis for determining when the work of the WG is completed
The work will be completed once it is apparent that maximal
consensus on the protocol proposal has been achieved within the
working group, consistent with the purpose and scope.
