协同编辑中维护操作意愿的文档标注方法*

在实时协同编辑系统中,操作意愿一致性维护是国际上提出的新概念,是协同系统一致性维护的重要方面.文档标注文法通过对共享文档进行恰当标注,屏蔽并发操作对共享文档造成的影响,使得操作在任意协作点上执行时的环境与操作产生的环境一致,从而有效地维护操作意愿一致性.结合实际应用中的具体操作,重点论述文档标注方法以及相应的控制算法.

Document Marking Scheme for Preserving Intention of Operationin Cooperative Editing System

Intention preservation of operation is a new proposed concept in the field of CSCW (computer-supported cooperative work), and the key feature of consistency control. A new called document marking scheme for intention preservation is proposed in this paper. By properly marking the sharing document, the document marking scheme can hide the effect of all concurrent operations of one operation. Therefore, operation can be performed at any cooperative side under the document environment just like it produced. Associating operations in a real-time cooperative editing system, the idea and the high-level control algorithm of the new method are presented in detail.
