This book constitutes the refereed proceeding of the 6th International Conference on Coordination Models and Languages, COORDINATION 2004, held in Pisa, Italy in February 2004.

The 20 revised full papers presented together with the abstracts of 3 invited talks were carefully reviewed and selected from 72 submissions. Among the topics addressed are context-aware coordination, the Linda coordination model, component adaptation, aspect-oriented programming, coordination middleware, peer-to-peer systems, coordination languages, network coordination, logic based coordination, agent coordination, as well as several coordination tools.
