Abstract : Currently, Wikis are the most popular form of collaborative editors. They allow users to concurrently edit and modify a shared set of wiki pages. We anticipate large increasing of amount and complexity of data. To face this problem, some researches have been done to shift from centralized architecture to fully decentralized wikis relying on peer-to-peer networks. However, this approach leads to new problem related to concurrency and the way remote modifications are integrated at each site. To overcome this problem, this thesis introduces the idea of concurrency awareness and proposes two contributions. The first one is to build a concurrency awareness mechanism for a P2P wiki. This mechanism makes users aware of the status of the pages they access regarding concurrency: is it an edited page or a merged page? In addition, in case of merged page, it indicates which region of the page has been merged. This mechanism depends over a concurrency detection mechanism which labels the generated patches by the set of servers. The second contribution deals with the representation of the concurrent history. Our visualisation is based over the classical history visualisation: the local versions are presented at the same order of their creation, and we added the information that present the status of these versions according to the concurrence.
