In a workstation environment, several applications operate concurrently and it is desirable to communicate between applications. The present invention provides an apparatus for communicating between applications by using an extensible communication protocol with a graphical user interface. The user transmits an interest object associated with an event from a second application to a server, which forwards the interest object to a first application. When the first application practices the event, information concerning the practice of the event is transmitted from the first application to the second application without going through the server.
