1MULTIMEDIA JOINT EDITING BASED ON RESERVATIONS

Joint editing as opposed to “normal ” editing is an activity carried out by several people simultaneously. It raises the problem of coordinating write access to a document. The approach described in this paper uses an editing model of reserved regions and a client/server architecture. Any region of a document may be selected and reserved (provided that it is not reserved already) and may then be changed by the owner. Other users can only read it. The software basis of the editor is the Andrew Toolkit. This allows the use of arbitrary media types within the document. Joint editing (also referred to as collaborative editing) is an area of research which was estab-lished nearly 10 years ago. It describes the general development of computer applications from tools for the individual user to software for the support of whole working groups (groupware1). This has influenced most areas of computer science research
