Real-time web-based collaborative editor

Abstract

Nowadays, revision control systems are used to support editing of documents by multiple authors. However, these systems do not provide an easy way to know what other authors are doing. To address this problem, real-time collaborative editing systems (CES) have been developed to enable editing of document by a group of authors over the network at the same time. The purpose of this project was to design and implement a real-time web-based collaborative XML editor that would be easier to use and deploy than the previous real-time collaborative editors. The overwrite problems and consistency problems were reduced by using the approaches of sectionlevel locking and centralized architecture. Our current implementation ran successful on Mozilla-based browsers, with near real-time syndication, where the maximum delay was adjusted by the server administrator. The basic objectives were met and the editor was usable.
