Request for consideration of AX 2.0 Working Group Charter Proposal

[Mike Jones]

Can you add a clear statement to the draft charter that implementations already using AX 1.0 will remain compatible with the output of this working group?  Or is backwards-compatibility with existing AX implementations not a goal of this work?

                                -- Mike

Subject: Request for consideration of Working Group Charter Proposal

I would like to submit the following proposal for a new Working Group
charter to your consideration, following the OpenID IPR process:

The proposal charter is also available at:
http://wiki.openid.net/Working_Groups:AX_2.0

OpenID Attribute Exchange 2.0 Working Group (AX 2.0)


Charter Proposal

In accordance with the OpenID Foundation IPR policies and procedures
this note proposes the formation of a new working group chartered to
produce an OpenID specification. As per Section 4.1 of the Policies,
the proposed charter is below (still liable to change during this
feedback period).


I. Name

Attribute Exchange Extension Working Group (AX)


II. Statement of Purpose

Produce an updated version of the Attribute Exchange Extension.


III. Scope

Update the Attribute Exchange Extension to include support for
identified needs. Currently identified needs:

    * Provide mechanisms for RP to require, and the OP to assert,
claims about the quality of the attributes.
    * Create an extensible registry of claim types, such as
axschema.org for attribute types. The registry should also provide
non-normative guidance on how claims can be validated, which will
depend on the nature of attribute type as well as claim type.
    * Introduce a new request/response mode which, unlike fetch and
store, allows for both transmittal of some values and request of
others. The transmittal not necessarily has the significance of a
"store" request (could be informative, or for requesting validation).
    * Introduce a direct communication method in both directions
(OP<->RP), supported via discovery, for bulk exchange of attributes
about (potentially) multiple users.


IV. Specifications

OpenID Attribute Exchange 2.0


V. Anticipated audience

All those interested in the obtaining attributes about users
authenticated via OpenID.


VI. Language of business

English.


VII. Method of work

Mailing list discussion. Posting of intermediate drafts in the OpenID
Wiki. Virtual conferencing on an ad-hoc basis.


VIII. Basis for completion of the activity

The Attribute Exchange 2.0 spec final draft is delivered and the form
of management and maintenance of the registry is established.
