As for the lack of the constraint on operations in traditional real-time collaborative environment, the paper introduces to adopt right allocation technique to support the document management of the shared document of different work groups.The paper gives formal definition of the Tree Document Model supporting role management, describes the configuration process of the roles, defines the formats of the right operations, proposes conflict detection and resolution strategies for Apply/Apply, Apply/Delete and Apply/Update conflicts.Besides, the paper improves the address space transformation strategy to guarantee the correct execution of the right operations in the distributed sites.Efficiency analysis of the improved algorithm is given and the application of this strategy in the Co-AutoCAD system proves the validity of the whole strategy.
