Groups include Working Groups, Interest Groups, Coordination Groups and Projects. Working Groups are small. The aim is to develop specs or code. Interest Groups provide a forum for the exchange of ideas. They do not have to have a small membership.
Membership is restricted to member organisations or non-members who have been invited by the chair.
Coordination Groups . Coordination Groups may be set up if a working Group feels that it would work better if the group were to be split. The membership and working practices will be defined by the Working Group which spawns them. Projects seek to develop systems which explot the Web. Projects may involve partenship with external organisations.
