Declarative Agent Languages and Technologies VI - 6th International Workshop, DALT 2008, Estoril, Portugal, May 12, 2008, Revised Selected and Invited Papers (Paperback, 2009 ed.)

The workshopon Declarative Agent Languagesand Technologies(DALT), in its sixth edition this year, is a well-established forum for researchers interested in sharing their experiences in combining declarative and formal approaches with aspects of engineering and technology of agents and multiagent systems. DALT2008washeldasasatelliteworkshopofAAMAS2008, the7thInter- tional Joint Conference on Autonomous Agents and Multiagent Systems, in - toril, Portugal. Following the success of DALT 2003 in Melbourne (LNAI 2990), DALT 2004 in New York (LNAI 3476), DALT 2005 in Utrecht (LNAI 3904), DALT 2006 in Hakodate (LNAI 4327), and DALT 2007 in Honolulu (LNAI 4897), the workshop again provided a discussion forum to both (a) support the transfer of declarative paradigms and techniques to the broader community of agent researchers and practitioners, and (b) to bring the issue of designing complex agent systems to the attention of researchers working on declarative languages and technologies. TheaimoftheDALTworkshopistostimulateresearchonformalanddecl- ative approaches both for developing the foundations of multiagent systems as well as for all phases of engineering multiagent systems, i.e., for speci?cation and modeling, for implementation, and for veri?cation. By providing a forum for the presentation of ideas addressing both of these aspects, DALT encourages the integrationof formal and declarativetechniques and methods that arebased on solid theoretical foundations in the engineering of multiagent systems
