Abstract
A collaborative application framework is used to build application programs which communicate with a central collaboration manager by means of a predetermined protocol. The predetermined protocol allows converters to be located at the collaboration manager site so that the programs neither include, nor require, preconfigured converters. Accordingly, new programs may easily and inexpensively be added to the system. The framework includes class code information which is incorporated into each application program by subclassing and which allows the program to communicate with the central manager by passing messages. The framework further includes class code for creating in the central manager a session object which receives a first message from a first program, converts the information in the first message into an information format utilized by a second program and forward a second messages to the second program containing information in the appropriate format. Since the converting mechanism is a part of a session object, it is not incorporated into first and second programs.
