层次结构文档下支持权限管理的实时协同技术研究

针对传统实时协同系统中各站点之间无约束操作的缺点,提出采用权限分工的方式来支持不同团队之间的文档管理。给出了支持权限管理的层次结构文档的形式化定义,描述了用户角色设置过程,定义了权限及权限操作格式,讨论了站点ID的设置及初始化过程,并提出采用改进的地址空间转换算法来保证权限操作在各分布式站点的正确执行。分析了改进算法的效率提升,并通过其在Co-AutoCAD中的应用证实了策略的有效性。

Research on real time collaboration technique supporting rightmanagement of layer-based document

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.
