  1. Overview of the W3C Leuven ZIG Meeting, July 2000

  2. W3C Was established in 1994 • To develop common protocols for the web, • promote its evolution, and • improve interoperability. • Motto: "lead the Web to its full potential"

  3. What is the W3C? • Two Views: • The W3C View • The cynical view

  4. W3C View "lead the Web to its full potential” AND ……… • ensure that the web remains a robust, scalable, and adaptive infrastructure; • make the web accessible to as many users as possible; • promote technologies that bridge differences in culture, education, ability, material resources, and physical limitations.

  5. Cynical View W3C is an invention of Microsoft, Netscape, and IBM, to enable them to bring products to market more quickly.
