摘　　要：文档协同编辑工具允许身处异地的多个用户通过网络协同编辑共享文档。目前仅有少量的商用软件支持对流式文档的协同编辑,这些工具在存储文档时要么是改变了文档的结构,要么是实现方法不公开,支持的文档类型有限。针对这一现状,构建了一个统一的文档模型,该模型抽取了OOXML、UOF和ODF中的公共语义信息,采用树状结构,通过API实现了模型和各流式文档逻辑结构之间的映射。基于模型,设计并实现了一个文档协同编辑系统。结果表明统一文档模型能较好地支持对流式文档的各种操作、修订管理和协同编辑功能。Real-time collaborative editing tools allow multiple users to edit shared documents synchronously at different sites. Only a few commercial tools support collaborative editing of fluid documents. When storing documents,these tools either change the document format,or only support limited kinds of fluid format,moreover,the implementation methods are not publicly available. To solve these problems, a tree-like unified document model is set up which extracts common semantic information from logical structure of OOXML,UOF and ODF to realize mapping into different logical structures through API. Based on the unified document model,a real-time collaborative system is implemented. The testing result shows that the unified document model can effectively support various kinds of common operations,revision management and synchronous editing for shared documents.
