Abstract: A multi-party online collaboration system that optimizes both the participation of the collaborators and the universality of membership is described. The system satisfies the two requirements for networked collaboration by providing shareable objects and a means of notifying the collaborators whenever the state of the shared objects has changed. For an open network (i.e., the Internet), the preferred embodiment uses two open standards mechanisms: URL-addressable networks for the accessible shareable objects, and asynchronous messaging for notification of changes to the objects that do not occur in real-time. The preferred embodiment employs these two open standards systems to ensure universal access, and obviates the need for the collaborators to install/maintain proprietary client systems. The preferred embodiment monitors the state of the objects, and automatically dispatches notification messages, along with addresses (e.g.
