This book constitutes the refereed proceedings of the First European Conference on Software Architecture, ECSA 2007, held in Aranjuez, Spain, September 24-26, 2007. The 12 revised long papers presented together with 4 short papers were carefully reviewed and selected from 62 submissions. Topics include description languages and metamodels, architecture-based code generation, run-time monitoring, requirements engineering, service-oriented architectures, aspect-oriented software architectures, ontology-based approaches, autonomic systems, middleware and web services.
