Abstract

Platform-independent collaboration backbone and framework for forming virtual communities having virtual rooms with collaborative sessions. Demon logic is embedded in a room page as downloadable platform-independent instructions. The demon, when downloaded, is caused to be in communication with control logic and an application, which, for example, may itself be downloadable. The downloaded demon is also in communication with a server. The server is in communication with similarly-arranged, though not necessarily identical, clients, which for example may have the downloaded demon but a different arrangement of applications. The application at a first and second client node may collaborate by causing their respective demons to send messages from a predefined protocol to the server, which in turn will forward them to other relevant demons. Some of the messages are control messages which facilitate certain collaborative actions, such as joining a session or entering a room. Other messages carry meaning only to the applications. The collaborating applications need not be identical, and the system provides minimal constraints on developers. For example, there is no requirement that the applications operate off an identical data model. Rooms may be organized into communities, which for example may specify certain commonality among rooms, such as common user-authentication. When a user changes from one room to another, if the new room is in a different community, the user will need to go through user authentication-procedures of the new community to permit access.
