协同写作是 Ｃ Ｓ Ｃ Ｗ 的一个重要研究领域．文中针对 Ｗ Ｗ Ｗ 文档的协同写作提出了一种文档目录树技术，不仅为 Ｗ Ｗ Ｗ 文档扩充了表示其全局结构的层次式目录结构，还为文档的分工协作写作提供了良好的数据组织结构．文中详细讨论了基于文档目录树结构对一个 Ｗ Ｗ Ｗ 文档进行协同写作时的协同机制，研究了多用户界面设计、协作方式、以及使用“目录路径锁定法”实现的并发控制等主要技术
Collaborative writing is an important area of C S C W research. In this paper, a document directory tree is proposed for WW W document collaborative writing, which not only expands the hierarchical directory structure that represents the global structure of W W W document, but also provides a good data organization structure for WORD document collaborative writing . The paper discusses in detail the collaborative mechanism of collaborative writing of a WMW document based on the document directory tree structure and the main techniques of multi-user interface design, collaboration and concurrency control using Directory Path Locking
