Membership Meetings

One of the most valuable benefits of W3C Membership is the opportunity for participants to develop working relationships with colleagues in many organizations, in many parts of the world. To bring people together and foster these relationships, W3C organizes Working Group meetings as well as two types of Membership-wide meetings each year:

TPAC ("Technical Plenary / Advisory Committee") During that week, a number of W3C Working, Interest, and Coordination Groups gather, network, and try to resolve challenging technical or social issues. This well-attended and popular week of meetings is an important means for W3C to coordinate solutions to technical issues that cross group borders. A "plenary session" with panels and other presentations brings all participants together; plenary meeting records are public. See past TPAC meetings.

Advisory Committee Meetings are Members-only meetings that focus on strategic issues facing the Consortium and future directions envisioned by the Membership and Staff. See past AC meetings (Member-only)
