Today it is still a challenge to deve- lop technologies that can satisfy the requirements of complex agent systems. Importantly, building multi-agent systems still calls for models and technologies that ensure predictability, enable feature discovery, allow the verification of properties, and guarantee fle- xibility. Declarative approaches are potentially a valuable means for satisfying the needs of multi-agent systems developers and for specifying multi-agent systems. The main goal of DALT is to provide a discussion to both (1) support the transfer of declarative paradigms and techniques into the broa- der community of agent researchers and practitioners, and (2) to bring the issues of designing real-world and complex agent system to the attention of researchers working on declarative programming and technologies. DALT topics of interst include, but are not limited to: * Declarative agent communication and coordination languages * Declarative approaches to the engineering of agent systems * Experimental studies of declarative technologies * Industrial and commercial experiences with declarative agent technologies * Formal methods for the specification and verification of agent systems * Distributed constraint satisfaction and constraint reasoning in agents * Multi-criteria optimisation and distributed problem solving with constraints * Computational logics in multi-agent systems * Model Checking MAS * Declarative description of contracts and negotiation issues * Lessons learned from the design and implementation of agent systems * Declarative paradigms for the combination of heterogeneous agents * Constraints and agent systems * Declarative policies and security in MAS * Knowledge-based and knowledge-intensive MAS * Modeling of agent rationality *Proceedings* A printed volume with the proceedings will be available at the work- shop. Authors of papers presented at the workshop will be asked to extend their contributions, possibly incorporating the results of the workshop discussion, to be included in the workshop post-procee- dings to be published in a journal special issue or a book. The DALT 2003 and 2004 post-proceedings are published by Springer as a volume of the Lecture Notes on Artificial Intelligence series. *Submission instructions* Papers should be written in English, formatted according to the Springer LNCS style, and not exceed 16 pages. Paper submission is electronic via the conference home page. *Important dates* Submission: March 18th, 2005 ! N E W !
