Page history last edited by Nat Sakimura 14 years, 5 months ago

Contract Exchange WG Charter (formally TX).

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 specifics of the proposed working group are:

Status: Active



(a) Charter.

(i) WG name

Contract Exchange Extension Working Group

(ii) Purpose

The purpose of this WG is to produce a standard OpenID extension to the OpenID Authentication protocol that enables arbitrary parties to create and exchange a mutually-digitally-signed "contract". This contract can be both broadband and mobile friendly through appropriate bindings that will be defined for each use case.

(iii) Scope

Scope of the work

Development of a specification that allows parties to exchange a mutually-digitally-signed contract leveraging on OpenID Authentication 2.0 and OpenID Attribute Exchange 2.0 via the appropriate bindings defined in the specification.

Out of scope

  • UI and user experience: The Working Group will develop the wire protocol and and any related processing mechanisms required to support it but user interface and experience is out of scope.
  • Public Key Discovery method: This functionality will be either defined in the XRD 1.0 specification currently in progress at the OASIS XRI TC or a mechanism that works with OpenID Authentication 2.0/2.1 discovery will be defined independently.
  • Terms negotiation: Actual negotiation of the terms of a contract should be dealt with out-of-band or by other specifications.
  • Assurance: These will be handled by third-party assurance programs or other identity governance frameworks.
  • Trust hierarchies. It is the intent that this specification be usable by any trust community, whether it uses conventional PKI hierarchies, peer-to-peer trust mechanisms, reputation systems, or other forms of trust assurance. The specification of any particular trust root, trust hierarchy, or trust policy is explicitly out of scope.

(iv) Proposed List of Specifications

  • Contract Exchange 1.0

Expected completion of the first iteration is in Q1 2009. 

(v) Anticipated audience or users of the work

Implementers of OpenID Providers and Relying Parties, especially those who require security and accountability features to exchange sensitive customer information (e.g. personally identifiable information and credit card numbers) responsibly among trusted parties. 

(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 possibly face-to-face meetings at conferences. 

(viii) Basis for determining when the work of the WG is completed

Drafts 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 drafts has been achieved, consistent with the purpose and scope.
