Ebook: Software Architecture: 2nd European Workshop, EWSA 2005, Pisa, Italy, June 13-14, 2005. Proceedings

The1stEuropeanWorkshoponSoftwareArchitecture(EWSA2004)washeldin St Andrews, Scotland on 21–22 May 2004. The workshop provided an inter- tional forum for researchers and practitioners from academia and industry to discuss a wide range of topics in the area of software architecture and to jointly formulate an agenda for future research. We were pleased to continue this forum in EWSA 2005. The importance of software architecture as a fundamental area of software engineeringcontinues togrow.Inaddition todescribingtheunderlyingstructure of software systems, architectures are now being used to model and understand dynamicbehavior.Newareasofstudy,whichhavetheirrootsincontrolsystems, arebeginningtoemerge.The?eldofautonomicsrequiresanunderlyingsoftware architecture to describe the executing computation as does any control system that involves system evolution. The range of papers in EWSA 2005 re?ected both the traditional and new applications of software architecture techniques. EWSA 2005 distinguished between three types of papers: research papers (which describe authors’ novel research work), a case study (which describes experiencesrelatedtosoftwarearchitectures)andpositionpapers(whichpresent concise arguments about a topic of software architecture research or practice). TheProgrammeCommitteeselected18papers(12researchpapers,4position papers, 1 case study, and 1 unrefereed invited paper) out of 41 submissions from 20 countries (Australia, Belgium, Brazil, Chile, China, Czech Republic, Finland, France, Germany, India, Italy, Ireland, Korea, Netherlands, Pakistan, Portugal, Spain, Switzerland, UK, USA). All submissions were reviewed by at least three members of the Programme Committee. Papers were selected based on originality, quality, soundness and relevance to the workshop. Credit for the quality of the proceedings goes to all authors of papers.

This book constitutes the refereed proceedings of the 2nd European Workshop on Software Architecture, EWSA 2004, held in Pisa, Italy in June 2005.The 12 revised full research papers, one revised case study, and four revised position papers presented together with one invited presentation on ongoing European projects on software architectures were carefully reviewed and selected from 41 submissions. All current aspects of software architectures are addressed ranging from foundational and methodological issues to application issues of practical relevance.
