Service-Oriented Computing- ICSOC 2008 Workshops: Icsoc 2008 International Workshops Sydney, Australia, December 1, 2008, Revised Selected Papers

TheInternationalConferenceonService-OrientedComputing(ICSOC)hasbeen tracking the developments in service-oriented computing since its early stages with the ?rst conference held in Trento, Italy in 2003. Today, service-oriented computing has become a mainstream computing paradigm with an increasing numberoforganizationsadoptingservice-orientedarchitecture(SOA). Whilethe mainICSOCconferencefocusesonthe coreissuesinservice-orientedcomputing, ICSOC workshops have played a major role in providing a forum for the disc- sion of emergent researchtopics. Starting in 2005 at the Amsterdam conference, workshops have been an integral component of the ICSOC conferences. While the number of workshops and the topics covered change from year to year, the quality of the workshoppublications has steadily increased with the most recent workshop proceedings published in the LNCS series by Springer. Re?ecting the growing interest in the area of service-orientedcomputing and the expanding ?eld of application of software services, the ICSOC 2008 c- ference in Sydney, Australia was accompanied by ?ve workshops focusing on speci?c research areas: • ForthInternationalWorkshoponEngineeringService-OrientedApplications (WESOA 2008) • Second International Workshop on Web APIs and Services Mashups (Mashups 2008) • First International workshop on Quality-of-Service Concerns in Service Oriented Architectures (QoSCSOA 2008) • First International Workshop on Enabling Service Business Ecosystems (ESBE 2008) • ThirdWorkshoponTrendsinEnterpriseArchitectureResearch(TEAR 2008) The 2008 workshops covered well-established areas of research such as the engineering of service-oriented applications (WESOA 2008), as well as eme- ing topics that include Web APIs and services mashups (Mashups 2008) and quality-of-service concerns (QoSCSOA 2008), and provided a forum for the - change of ideas between researchers and practitioners in the speci?c research areas.
