Many organizations in addition to W3C develop standards for the Internet or the Web. In order coordinate the development of the Web, W3C engages in liaisons with numerous organizations after careful consideration of the costs and benefits.

Mission of W3C International Liaisons

W3C is determined to improve W3C's liaisons with international organizations in the areas of policy and standardization and to reinforce W3C's commitment to developing one Web for all. The W3C staff provides the leadership to coordinate and to empower W3C Offices. The staff acts as a catalyst and enabler for both the W3C management team and the Offices, with whom it shares best practices and resources.

International Relations focuses on spreading W3C's messages and technologies beyond the Consortium's usual geographical and Web community frontiers. We pursue the vision and plan outlined in the white paper Worldwide Participation in the World Wide Web Consortium with the goal of making it easier for new stakeholders to discover and participate in W3C's work and values.

Contacting W3C to Establish a Liaison

The best way to reach W3C about liaisons and partnerships is to send email to team-liaisons@w3.org which will reach Daniel Dardailler, Rigo Wenning, Wendy Seltzer, Jeff Jaffe, and other W3C staff members active in the area. Please see the public International Relations page of W3C.

We have additional information about participation in W3C by EU-funded projects.

For relationships between W3C and government driven organizations like ISO, ITU, EU normalization (ETSI, CEN), UN efforts like IGF/WSISs, national bodies (ANSI, AFNOR, etc.), and for political liaison activities with other Internet organizations like IETF, ICANN, ISOC, etc., please cc Daniel Dardailler in any case.

If you prefer private communication, please contact Daniel Dardailler.

About the Liaison Table

Each entry in the following table of partnerships (active or not) includes:

  • the name of the organization, linked to its homepage. In addition, formal agreements can be listed here.
  • the W3C activities or technologies affected by the liaison
  • one or several contact names within W3C
  • one or several liaison contact names (preferrably using an http URL, rather than a mailto)

For more information about a particular liaison, please refer to the contact page for the listed individual(s).

Considerations When Establishing a Liaison

W3C finds its liaisons fall into two categories:

We list both types of liaisons in the table above. Per the W3C ProcessDocument, all liaisons, of any kind, must be coordinated by the Team due to requirements for public communication, IPR or confidentiality policies. Mutual membership agreements are also possible.

W3C may choose not to pursue a liaison with an organization that has selective or arbitrary membership policies that serve only to benefit pre-existing or dominant members.

To request any liaison, please send a brief email to the liaison contact.

Simple liaisons

In general, the goal of a simple liaison is for both parties to gain a better understanding of their respective activities and look for opportunities to work together. For example, W3C appreciates understanding how other organizations use W3C technology, whether they require extensions, the proper way to manage those extensions, how to bring extensions back into W3C, and so on. Other organizations may find a simple liaison valuable for soliciting W3C input on a Web-related question.

Most often, W3C establishes simple liaisons with non-profit organizations, other standards bodies, or any other entity that may wish to build consensus around an emerging Web technology. Simple liaisons are active as soon as both partie agree to make the information public in this page.

Formal Agreements for Joint Work

In some cases, W3C is asked to establish a formal liaison that has a contractual framework, either because there are joint deliverables, or an agreed share of technical responsibilities with coordination, with considerations for confidentiality, shared press coverage, or IPR.

While W3C supports all liaisons with other groups, the organization and development of these formal liaisons requires time and resources, and the agreement of the W3C membership at large, so. W3C's decision to pursue a liaison with a Partner is ultimately based on the perceived costs and benefits.

For an historical record of how Formal Liaisons are created, please see the 2003 Process Document, which used to described the details (no longer the case in the current Process).

W3C and De Jure Standards

This section describes some of W3C's relationships with de jure bodies such as ISO, in addition to the direct technical activity liaisons mentioned above.

W3C is an "ISO/IEC JTC 1 PAS" Submitter

At the end of October 2010, W3C was approved as a JTC 1 Recognized PAS Submitter for an overall scope defined as "any stable core Web technologies produced by W3C that are also in scope of JTC 1". The PAS process is standard transposition procedure whereby organizations accredited as valid PAS Submitters can send their specifications directly for country voting, to become ISO/IEC standards. See the W3C PAS Submission FAQ.

W3C Approved RS Originator Organization (ARO) Status for ISO/JTC1

In January 2007, W3C became an Approved RS Originator Organization (ARO) for ISO/JTC1. This means that ISO/JTC1 standards may refer to W3C Recommendations "as-is." That process is described in the Letter Ballot on the JTC 1 Standing Document on Normative References

For more information about W3C's ARO or PAS status, please contact Daniel Dardailler <danield@w3.org>.
