Peer-to-Peer (P2P) architectures for content and knowledge management enable autonomous peers to interoperate in a decentralized and distributed fashion for fulfilling individual and/or common goals. These architectures foster the creation of communities of Individual Knowledge Workers (IKWs) in which effective knowledge and information sharing takes place. In such communities, IKWs have similar capabilities in providing other IKWs with data and/or services and are autonomous in managing their own knowledge objects. Since such objects are typically shared among a set of IKWs, problems regarding concurrent access to content, content consistency and synchronization arise. This paper proposes a decentralized approach to the aforementioned issues and reports on its application and performance evaluation in the K-link+ system. K-link+ is a P2P collaborative platform, developed at the GridLab of the University of Calabria, for distributed knowledge management based on the Virtual Office model.
