An object-based model for cooperative computing

A cooperative computing model is presented to support the construction of CSCW systems. The model divides a cooperative system into layers and each layer is formed by component objects. A principal focus of the model is the provision of an object linking mechanism which links the relevant objects in the same layer of multiple users to realize multi-level collaboration which is independent of the application. In addition, multi-level collaboration obtains fine-grained collaboration and improves collaboration efficiency. The object-based method used ensures a structured collaboration and facilitates cooperative system development.
