XWiki Concerto: Peer-to-Peer Extension of XWiki

Participants : Gérôme Canals [ contact ] , Pascal Molli, Julien Maire, Gérald Oster, Claudia-Lavinia Ignat.

XWiki Concerto(http://concerto.xwiki.org ) is a peer-to-peer extension of the XWiki system, an open-source enterprise wiki. This extension is the result of the ANR XWiki Concerto. An XWiki Concerto network is an unstructured peer-to-peer network of XWiki servers where each server stores a copy of the replicated wiki pages. XWiki Concerto uses an epidemic propagation algorithm to broadcast changes on the overlay network, combined with the woot algorithm to merge concurrent changes. XWiki Concerto is scalable, and supports dynamic networks and disconnected operations.
