Abstract

Awareness about the document evolution is an important part in collaborative editing systems. It is represented always by the versions history. The representation of the document history in centralized collaborative editing systems is linear. However, in distributed collaborative editors, there is no central server and the users can work asynchronously or in isolation and some versions may be produced concurrently, in this case, the history is no long linear. The existing history representations are limited because they don’t provide any information about the concurrence on the document history. We introduce here a non linear representation for the page history in P2P wiki systems. The concurrency information about the page versions is provided; the user can explore the page versions that resulted under the user’s control or produced by the server in case of merging concurrent modifications.
