This paper presents the XWiki Concerto system, the P2P version of the XWiki server. This system is based on replicating wiki pages on a network of wiki servers. The approach, based on the Woot algorithm, has been designed to be scalable, to support the dynamic aspect of P2P networks and network partitions. These characteristics make our system capable of(More)
In this paper, we address data reconciliation in peer-to-peer (P2P) collaborative applications. We propose P2P-LTR (Logging and Timestamping for Reconciliation) which provides P2P logging and timestamping services for P2P reconciliation over a distributed hash table (DHT). While updating at collaborating peers, updates are timestamped and stored in a highly(More)

Replication is a topic of interest in the distributed computing, distributed systems, and database communities. Decision support systems became practical with the development of minicomputer, timeshare operating systems and distributed computing. Replicated data may get insufficient due to system failure, fault tolerance, and reliability. A partial(More)
Distributed Hash Tables (DHTs) provide an efficient solution for data location and lookup in large-scale P2P systems. However, it is up to the applications to deal with the availability of the data they store in the DHT, e.g. via replication. To improve data availability, most DHT applications rely on data replication. However, efficient replication(More)
XWiki Concerto is a research project aiming at evolving the open-source XWiki engine toward a P2P architecture supporting mobility, offline work and replication of content across a large number of peers. This research brings XWiki the capacity to (i) run on a fault tolerant P2P architecture allowing to scale to millions of users using a secure solution(More)
