Abstract: Operation transformation technique is not perfect in solving concurrency control of real-time distributed cooperative systems. This article proposes 2-dimension sequential state vector operation transformation algorithm and also presents a solution of LateComer. The algorithm improves efficiency and continuity of cooperative editing.

Key words: Collaborative editing, Concurrency control, Operation transformation
