W3C W3C Liaisons With Other Organizations

The World Wide Web Consortium (W3C) is the organization where core Web technologies are developed. There are many other organizations developing standards for the Internet or the Web in general, and in some cases, their activities may overlap with W3C activities. To help coordinate the development of the Web, W3C engages in liaisons with numerous organizations after careful consideration of the costs and benefits.

Considerations When Establishing a Liaison

Liaisons take a variety of forms, ranging from participation by an individual in a group, to membership agreements, to formal agreements through Memorandum of Understanding (MoU) or other contracts. While W3C supports liaisons with other groups, the organization and development of these liaisons (formal or informal) requires time and resources. W3C's decision to pursue a liaison with a Partner is ultimately based on the perceived costs and benefits to W3C. Important considerations include:

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.

Per the W3C Process Document, all liaisons must be coordinated by the Team due to requirements for public communication; patent, copyright, and other IPR policies; confidentiality agreements; and mutual membership agreements.
