In Supporting of Distributed Co-Editing Environment

Abstract

In the present paper, we focused on the development of multi-participants co-editing scheme. Due to the participant common interests any have intersection, data conflict occurs. To resolve this issue, conventional approaches face the tradeoff between data consistency and concurrent operation. We analyzed the possible operations of text editing. We oound out that many undo processes can be avoided. In other words, data consistency is still ensured without sacrificing system performance. Based on the analysis, we developed an algorithm, called Temporal And Spatial Data conflict detection (TASD), in solving data conflicts effectively. The proposed algorithm can resolve many data conflicts without the undo operation.
