At IIW yesterday I held a session on bashing the OpenID v.Nest Core Protocol Charter. Below is the current draft. Comments and/or questions welcome. Anyone interested in being a fellow proposer please let me know and I will add you.

(a)  Charter.

(i)                  WG name:  OpenID v.Next Core Protocol.
(ii)                  Purpose:  Produce a core protocol specification or family of specifications for OpenID v.Next that address the limitations and drawbacks present in the OpenID 2.0 that limit OpenID’s applicability, adoption, usability, privacy, and security.  Specific goals are:
·       define message flows and verification methods,
·       enable support for controlled release of attributes,
·       enable aggregation of attributes from multiple verifiable sources,
·       enable support for a spectrum of clients, including passive clients per current usage, thin active clients, and active clients with OP functionality,
·       enable authentication to and use of attributes by non-browser applications,
·       enable the use of public key technology to enhance scalability and performance,
·       enable optimized protocol flows combining authentication, attribute release, and resource authorization,
·       define profiles and support features intended to enable OpenID to be used at levels of assurance higher than NIST SP800-63 v2 level 1 ,
·       define an extension mechanism
·       ensure the use of OpenID on mobile devices,
·       ensure the use of OpenID on existing browsers with URL length restrictions,
·       complement OAuth 2.0
·       minimize migration effort from OpenID 2.0
·       seamlessly integrate with and complement the other OpenID v.Next specifications.
              Compatibility with OpenID 2.0 is an explicit non-goal for this work.
(iii)                  Scope:  Produce a next generation OpenID core protocol specification or specifications, consistent with the purpose statement.
(iv)                  Proposed List of Specifications:  OpenID v.Next Core Protocol and possibly related specifications.
(v)                  Anticipated audience or users of the work:  Implementers of OpenID Providers, Relying Parties, Active Clients, and non-browser applications utilizing OpenID.
(vi)                  Language in which the WG will conduct business:  English.
(vii)                  Method of work:  E-mail discussions on the working group mailing list, working group conference calls, and face-to-face meetings at the Internet Identity Workshop and OpenID summits.
(viii)                  Basis for determining when the work of the WG is completed:  Work will not be deemed to be complete until there is a consensus that the resulting protocol specification or family of specifications fulfills the working group goals.  Additional proposed changes beyond that initial consensus will be evaluated on the basis of whether they increase or decrease consensus within the working group.  The work will be completed once it is apparent that maximal consensus on the draft has been achieved, consistent with the purpose and scope.
(b)  Background Information.

(i)                  Related work being done in other WGs or organizations:  OpenID Authentication 2.0 and related specifications, including Attribute Exchange (AX), Contract Exchange (CX), Provider Authentication Policy Extension (PAPE), and the draft User Interface (UI) Extension.  OAuth, OAuth WRAP, and OAuth 2.0.  OpenID Connect proposal. SAML 2.0 Core and SAML Authn Context.
