ABSTRACT
This paper examines the importance of providing effective management of sharing in cooperative systems and argues for a specialised service to support the cooperative aspects of information sharing. The relationship between features of the cooperative shared object service and existing services is briefly examined. A number of management services of particular importance to CSCW systems are identified. The paper presents a technique of realising a shared object service by augmenting existing object facilities to provide management of their cooperative use. These facilities are realised through object adapters that provide additional cooperative facilities and greater control over the supporting infrastructure.
