The Web Services Core Working Group is chartered to consider comments and updates on the existing Web Services W3C Recommendations and affiliated W3C Working Group Notes. It includes:

Note: the Working Group will also take over the maintenance of the Recommendations and Working Group Notes produced by the XML Protocol, Web Services Policies, Semantic Annotations for WSDL, XML Schema Patterns for Databinding, and Web Services Choreography Working Groups after the completion of those groups. This potentially includes:

The Working Group is responsible for updating errata documents, publishing new editions incorporating published errata when appropriate, and maintaining the associated test suites and XML Schema documents. The Working Group will only apply changes of classes 1, 2, and 3, as outlined in section 7.6.2, “Classes of Changes to a Recommendation”, of the World Wide Web Consortium Process Document.

The Working Group will review documents produced by other Web Services and XML related Working Groups when appropriate.

Success Criteria

All comments received against one of the maintained specifications will receive some reply from the Working Group within 45 days. The Web Services issues lists are kept up-to-date with no more than 45 days lag from the original posting of a potential issue.

Out of Scope

The Working Group will not apply changes of class 4, as outlined in section 7.6.2, “Classes of Changes to a Recommendation”, of the World Wide Web Consortium Process Document. The Working Group will not produce documents that require following the full process of advancing a technical report to Recommendation. A new Working Group would need to be created to achieve that effect.


The Working Group will publish second editions of the W3C Recommendations and revisions of the Working Group Notes when appropriate. Note that the development of new W3C Recommendations not listed in this document would require a new Working Group.

Other Deliverables

The Web Services Core Working Group is responsible for maintaining the test suites associated with the specifications listed in the Scope section and providing careful updates as warranted. The Group is also encouraged to enhance the existing test suites to ensure cross-specification interoperability.

This Working Group handles core Web Services issues and as such may deal from time to time with several other specifications beyond those specifically listed in the scope.


W3C Groups

Web Services Activity
The Web Services Core Chairs participate in the Web Services Coordination Group to help track dependencies.
Technical Architecture Group
The Web Services Core Working Group will coordinate with TAG for issues related to the Web architecture.

External Groups

The Web Services Core Working Group should liaise with at least the following groups outside W3C:

The Internet Engineering Task Force
The Web Services Core Working Group will liaise with the IETF to discuss all transport protocol issues that are relevant for Web Services. For issues that are not clearly in the realm of an existing IETF Working Group, the IETF/W3C coordination call should be used as the discussion forum.
Organization for the Advancement of Structured Information Standards
OASIS is a not-for-profit, international consortium that drives the development, convergence and adoption of e-business standards.
Web Services Interoperability Organization
The Web Services Interoperability Organization is an open industry effort chartered to promote Web Services interoperability across platforms, applications, and programming languages through the development of profiles, any one of which could be relevant to the scope of the Web Services Core Working Group.


Participation in the Web Services Core Working Group is open to the W3C Members, and individuals with expertise in Web Services who are invited by the Working Group Chair and approved by the Team Contact (see also the policy for approval of Invited Experts). Invited Experts in this group are not granted access to Member-only information.

There are no minimum requirements for participation in this group. Participants are strongly encouraged to take advantage of frequent opportunities to review and comment on deliverables from other groups.

The Chair may call occasional meetings consistent with the W3C Process requirements for meetings.


This group primarily conducts its work on the public mailing list www-ws@w3.org (archive).

Information about the group (deliverables, participants, teleconferences, etc.) is available from the Web Services Core Working Group home page.

Decision Policy

As explained in the Process Document (section 3.3), this group will seek to make decisions when there is consensus. When the Chair puts a question and observes dissent, after due consideration of different opinions, the Chair should record a decision (possibly after a formal vote) and any objections, and move on.

This charter is written in accordance with Section 3.4, Votes of the W3C Process Document and includes no voting procedures beyond what the Process Document requires.

Patent Disclosures

The Web Services Core Working Group provides an opportunity to share perspectives on the topics addressed by this charter. W3C reminds Working Group participants of their obligation to comply with patent disclosure obligations as set out in Section 6 of the W3C Patent Policy. While the Working Group does not produce new Recommendation-track documents, besides new editions of existing Recommendations, when Working Group participants review Recommendation-track specifications from Working Groups, the patent disclosure obligations do apply.

For more information about disclosure obligations for this group, please see the W3C Patent Policy Implementation.

About this Charter

This charter for the Web Services Core Working Group has been created according to section 6.2 of the Process Document. In the event of a conflict between this document or the provisions of any charter and the W3C Process, the W3C Process shall take precedence.
