基于Web的实时协同编辑系统中的一致性控制

作为CSCW的一个重要应用领域，协同编辑系统近年来有了长足的进步，各种此类系统相继出现并投入了使用，但是，大部分系统由于不能很好地解决一致性问题，目前大多不支持脑风暴方式的编辑，主要介绍如何利用GOTO算法在基于WEB的实时协同编辑系统中解决一致性问题，其中包括了对系统结构、系统一致性问题、GOTO算法、操作相关性检测及操作转换的介绍，最后，对基于GOTO算法的实验系统WRCES进行了简单的介绍。

CONSISTENCY MAINTENANCE IN WEB-BASED REAL-TIME COOPERATIVE EDIT SYSTEM

As a very important field of CSCW, cooperative edit systems have a rapid development in recent years. Many systems have arisen and been put into use. But most of them don't support the brain storm edit mode, because they can't settle the consistency problem primarily. Introduced in this paper is how to use the GOTO arithmetic to settle the consistency problem in a Web-based real-time cooperative edit system. It includes the following contents: system architecture, inconsistency problems, GOTO arithmetic, operation dependence checking and operation transformation. Finally, the experiment system WRCES, which is based on the GOTO arithmetic, is also introduced.
