Maintaining Consistency In A Web 2.0 Collaborative Editing System

Web based collaborative editors are increasingly required within Web 2.0 era. Since this involves group editing, concurrency control and consistency of the updates needs to be addressed. In this paper we present an optimistically concurrent and serialization algorithm for Web based real-time group editing of XHTML documents. The algorithm uses standard W3C document object model (DOM) as its data representation model in the runtime environment. We implemented this algorithm in a Web 2.0 collaborative editor system, and at this time provide some preliminary observations on the working system.
