Abstract

Multimedia applications and groupware (or computer-supported cooperative work — CSCW) represent the two new trends within office information systems. Those two applications are characterized mainly by the new type of information they process and by the distributed system architecture upon which they are built. The information type is composed of text, graphics, pictures, sound and motion video, while the distributed system ingredients can also take a variety of forms: local networks, wide area networks, synchronous and asynchronous mode of interaction. When both applications are provided in the same solution (e.g. cooperative work which uses multimedia technology), many issues should be solved at various levels: the workstations, the network with its associated protocols, the data model and the performance of the overall system. This paper focuses on the application level and describes the trend towards fixed document based applications, namely publishing and imaging systems, and more advanced types of documents where motion and sound can be intermixed in the same document, and various objects constituting the documents are inter-related with links.
