Abstract

Collaborative web-based applications support users when creating and sharing information. Wikis are prominent examples for that kind of applications. Wikis, like e.g. Wikipedia [1], attract loads of users that modify its content. Normally, wikis do not employ any mechanisms to avoid parallel modification of the same page. As result, conflicting changes can occur. Most wikis record all versions of a page to allow users to review recent changes. However, just recording all versions does not guarantee that conflicting modifications are reflected in the most recent version of a page. In this paper, we identify the requirements for efficiently dealing with conflicting modifications and present a web-based tool which allows to compare and merge different versions of a wiki page.
