COLLABORATION SUPPORTING MODEL OF SHARED OBJECTS FOR CSCW SYSTEMS

Information sharing is the basis of multi user collaboration in CSCW systems. First the requirements for the service of shared objects in CSCW is analysied. Then a collaboration supporting model of shared objects SOCSM/LSI is presented. The SOCSM/LSI uses the layered service interface to implement the cooperative functions such as access control, group awareness, and different presentation of shared objects. The SOCSM/LSI model can provide dynamic and flexible cooperative mechanisms for shared objects and can be applied to a quite wide range of CSCW applications.
