Constitutes the refereed proceedings of the 2nd European Workshop on Software Architecture, EWSA 2004, held in June 2005. The research papers in this book, review the European projects on software architectures. They also address topics ranging from foundational and methodological issues to application issues of practical relevance.

The last decade has been one of great progress in the field of software architecture research and practice. Software architecture has emerged as an important subdis- pline of software engineering. A key aspect of the design of any software system is its architecture, i. e. the fundamental organization of a system embodied in its com- nents, their relationships to each other, and to the environment, and the principles guiding its design and evolution (as defined in the Recommended Practice for Arc- tectural Description of Software-Intensive Systems -- IEEE Std 1471-2000). - The First European...
