Currently, Wikis are the most popular form of collaborative editors. Recently, some researches have proposed fully decentralized wikis relying on peer-to-peer networks. This new architecture subtly changes the behavior of wiki in case of concurrent changes. While traditional wikis ensure that all pages have been reviewed by a user, some pages in a P2P wiki are produced by the system through a automatic merge. To overcome this problem, this paper introduces concurrency awareness, a mechanism that makes users aware about the status of wiki pages. The particular context of a P2P wiki system makes traditional awareness mechanisms inadequate and requires the desgin of a new one.
Abstract. DSMW is an extension to Semantic Mediawiki (SMW), it allows to create a network of SMW servers that share common semantic wiki pages. DSMW users can create communication channels between servers and use a publish-subscribe approach to manage the change propagation. DSMW synchronizes concurrent updates of shared semantic pages to ensure their consistency. It offers new collaboration modes to semantic wiki users and supports dataflow-oriented processes.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
