Modern information systems rely increasingly on combining concurrent, distributed, mobile, reconfigurable and heterogenous components. New models, architectures, languages, verification techniques are necessary to cope with the complexity induced by the demands of today's software development. Coordination languages have emerged as a successful approach, in that they provide abstractions that cleanly separate behavior from communication, therefore increasing modularity, simplifying reasoning, and ultimately enhancing software development.

Building on the success of the previous editions, this conference provides a well-established forum for the growing community of researchers interested in models, languages, architectures, and implementation techniques for coordination.

Topics of interest include but are not limited to:

• Theoretical models and foundations for coordination: component composition, concurrency, mobility, dynamic aspects of coordination.
• Specification, refinement, and analysis of software architectures: patterns and styles, verification of functional and non-functional properties.
• Coordination, architectural, and interface definition languages: implementation, interoperability, heterogeneity.
• Agent-oriented languages: formal models for interacting agents.
• Dynamic software architectures: mobile code and agents, configuration, reconfiguration.
• Coordination and modern distributed computing: Web services, peer-to-peer networks, grid computing, context-awareness, ubiquitous computing.
• Tools and environments for the development of coordinated applications: integration within the development process.
• Industrial relevance of coordination and software architectures: programming in the large, domain-specific software architectures and coordination models, case studies.

The conference proceedings will be published by Springer, in the Lecture Notes in Computer Science (LNCS) series. Proceedings of the previous editions of this conference are also available in the LNCS series: volumes 1061, 1282, 1594, 1906, 2315, and 2949.

Moreover, a selection of the best papers will be published in a special issue of Science of Computer Programming.

Authors are invited to submit full papers electronically in PostScript or PDF using a two-phase online submission process. Registration of the paper information and abstract (max. 250 words) must be completed before December 15, 2004. Submission of the full paper is due no later than December 21, 2004. Submission will be handled through the conference management system.

Submissions must be formatted according to the LNCS guidelines and must not exceed 15 pages in length. Papers that are not in the requested format or significantly exceed the mandated length may be rejected without going through the review phase.

Submissions should explicitly state their contribution and their relevance to the theme of the conference. Other criteria for selection will be originality, significance, correctness, and clarity.

Simultaneous or similar submissions to other conferences or journals are not allowed.
