ICSOC 2007 followed the footsteps of four previous successful editions of the International Conference on Service-Oriented Computing that were held in Chicago,USA(2006),Amsterdam,TheNetherlands(2005),NewYorkCity,USA (2004) and Trento, Italy (2003). ICSOC is recognized as the ?agship conference for service-oriented computing research and best practices. ICSOC covers the entire spectrum from theoretical and foundational results to empirical eval- tion, as well as practical and industrial experiences. ICSOC 2007 continued this tradition while introducing several new themes to further these goals. Service-orientedcomputingbringstogetherideasandtechnologiesfrommany diverse ?elds in an evolutionary manner in order to address research challenges including service-based application modeling, service composition, discovery, - tegration, monitoring and management of services, service quality and security, methodologies for supporting service development, grid services, and novel t- ics including information as a service and service-oriented architecture (SOA) governance. To provide a balanced coverage and an equal emphasis across all aspects of service-oriented computing, ICSOC 2007’s topics were divided into seven major areas: Business Service Modeling, Service Assembly, and Service Management, addressing research issues and best practices in the primary life-cycle phases of a service, modeling, assembly, deployment, and management; SOA Runtime and Quality of Service, covering issues spanning all stages of the life-cycle; Grid Services and Service Architectures, combining grid infrastructure concepts with service-oriented computing; and Business and Economical Aspects of Services.weiterlesen
