Service-Oriented Computing - ICSOC 2008

This volume contains the conference proceedings of ICSOC 2008, the 6th Inter- tional Conference on Service-Oriented Computing, which took place in Sydney, A- tralia, December 1-5, 2008; it comprises research, industry and demo papers. ICSOC 2008 built upon the tradition of ?ve previous successful editions that were held in Vienna, Austria (2007), Chicago, USA (2006), Amsterdam, The Netherlands (2005), New York City, USA (2004) and Trento, Italy (2003). ICSOC is recognized as the premier conference for service-oriented computing research; it covers the entire sp- trum from theoretical and foundational results to empirical evaluations to practical and industrial experiences. In addition, ICSOC 2008 has successfully demonstrated the cross-disciplinary nature of service engineering by building bridges with the business community, and by attracting contributions on service-oriented systems of systems integration.

This shift toward ?exible service integration also requires a deep understanding and, often, rethinking of end-to-end systems engineering processes, including the corresponding business and economic drivers for de?nition of, or changes to, enterprise architectures.
