This book constitutes the thoroughly refereed post-proceedings of the 4th International Workshop on Agents and Peer-to-Peer Computing, AP2PC 2005, held in Utrecht, Netherlands, July 2005, in the context of the 4th International Joint Conference on Autonomous Agents and Multi-Agent Systems, AAMAS 2005. The 13 revised full papers cover trust and reputation, P2P infrastructure, semantic infrastructure, as well as community and mobile applications.

The aim of the International Workshop on Databases, Information Systems and P2P Computing was to explore the promise of P2P to o?er exciting new p- sibilities in distributed information processing and database technologies. The realization of this promise lies fundamentally in the availability of enhanced services such as structured ways for classifying and registering shared infor- tion, veri?cation and certi?cation of information, content distributed schemes and quality of content, security features, information discovery and accessib- ity, interoperation and composition of active information services, and ?nally market-based mechanisms to allow cooperative and noncooperative information exchanges. The P2P paradigm lends itself to constructing large-scale, complex, adaptive, autonomous and heterogeneous database and information systems, endowed with clearly speci?ed and di?erential capabilities to negotiate, bargain, coordinate and self-organize the information exchanges in large-scale networks. This vision will have a radical impact on the structure of complex organizations (business, sci- ti?c or otherwise) and on the emergence and the formation of social communities, and on how the information is organized and processed. The P2P information paradigm naturally encompasses static and wireless connectivity and static and mobile architectures. Wireless connectivity combined with the increasingly small and powerful mobile devices and sensors poses new challenges as well as opp- tunities to the database community. Information becomes ubiquitous, highly distributed and accessible anywhere and at any time over highly dynamic, - stable networks with very severe constraints on the information management and processing capabilities.

This book constitutes the thoroughly refereed post-workshop proceedings of the 5th International Workshop on Agents and Peer-to-Peer Computing, AP2PC 2006, held in Hakodate, Japan, in May 2006, in the context of the 5th International Joint Conference on Autonomous Agents and Multi-Agent Systems, AAMAS 2006. The 10 revised full papers and 6 revised short papers presented together with 1 invited paper were carefully reviewed and selected from 23 submissions; they are fully revised to incorporate reviewers' comments and discussions at the workshop. The volume is organized in topical sections on P2P Infrastructure, agents in P2P, P2P search, and applications.

This book constitutes the thoroughly refereed post-workshop proceedings of the 6th International Workshop on Agents and Peer-to-Peer Computing, AP2PC 2007, held in Honululu, Hawaii, USA, in May 2007, in the context of the 6th International Joint Conference on Autonomous Agents and Multi-Agent Systems, AAMAS 2007.
