%X As for the lack of the constraint on operations in traditional real-time collaborative environment, this paper introduced adopting right division technique to support the document management of the shared document of different work groups. The paper gave formal definition of the layer document supporting role management, described the configuration process of the roles, defined the formats of the right operations, and discussed the set up of the site IDs and the initialization process of them. Beside, the paper improved 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.
