Logoot-undo: Distributed collaborative editing system on P2P networks IEEE Transactions on Parallel and Distributed Systems 2010 Peer-to-peer systems provide scalable content distribution for cheap and resist to censorship attempts. However, {P2P} networks mainly distribute immutable content and provide poor support for highly dynamic content such as produced by collaborative systems. A new class of algorithms called {CRDT} {(Commutative} Replicated Data Type), which ensures consistency of highly dynamic content on {P2P} networks, is emerging. However, if existing {CRDT} algorithms support the edit anywhere anytime feature they do not support the "undo anywhere anytime feature. In this paper we present the {Logoot-Undo} {CRDT} algorithm which integrates the "undo anywhere anytime feature. We compare the performance of the proposed algorithm with related algorithms and measure the impact of the undo feature on the global performance of the algorithm. We prove that the cost of the undo feature remains low on a corpus of data extracted from Wikipedia. " 0 0
Logoot: A scalable optimistic replication algorithm for collaborative editing on P2P networks Proceedings - International Conference on Distributed Computing Systems English 2009 Massive collaborative editing becomes a reality through leading projects such as Wikipedia. This massive collaboration is currently supported with a costly central service. In order to avoid such costs, we aim to provide a peer-to-peer collaborative editing system. Existing approaches to build distributed collaborative editing systems either do not scale in terms of number of users or in terms of number of edits. We present the Logoot approach that scales in these both dimensions while ensuring causality, consistency and intention preservation criteria. We evaluate the Logoot approach and compare it to others using a corpus of all the edits applied on a set of the most edited and the biggest pages of Wikipedia. 0 0
Multi-synchronous collaborative semantic wikis Lecture Notes in Computer Science English 2009 Semantic wikis have opened an interesting way to mix Web 2.0 advantages with the Semantic Web approach. However, compared to other collaborative tools, wikis do not support all collaborative editing mode such as offline work or multi-synchronous editing. The lack of multi-synchronous supports in wikis is a problematic, especially, when working with semantic wikis. In these systems, it is often important to change multiple pages simultaneous in order to refactor the semantic wiki structure. In this paper, we present a new model of semantic wiki called Multi-Synchronous Semantic Wiki (MS2W). This model extends semantic wikis with multi-synchronous support that allows to create a P2P network of semantic wikis. Semantic wiki pages can be replicated on several semantic servers. The MS2W ensures CCI consistency on these pages relying on the Logoot algorithm. 0 0
Undo in peer-to-peer semantic wikis CEUR Workshop Proceedings English 2009 The undo mechanism is an essential feature in collaborative editing systems. Most popular semantic wikis support a revert feature, some provide an undo feature to remove any modification at any time. However this undo feature does not always succeed. Supporting the undo mechanism for P2P semantic wikis has never been tackled. In this paper, we present an undo approach for Swooki, the first P2P semantic wiki.We identify the problems to resolve in order to achieve such mechanism for P2P semantic wikis.We give the definition of the undo and the properties that must ensure. This approach allows both a revert and a permanent successful undo. 0 0
Wooki: A P2P wiki-based collaborative writing tool Lecture Notes in Computer Science English 2007 Wiki systems are becoming an important part of the information system of many organisations and communities. This introduce the issue of the data availability in case of failure, heavy load or off-line access. We propose to replicate wiki pages across a P2P network of wiki engines. We address the problem of consistency of replicated wiki pages in the context of a P2P wiki system. In this paper, we present the architecture and the underlying algorithms of the wooki system. Compared to traditional wikis, Wooki is P2P wiki which scales, delivers better performances and allows off-line access. 0 0
