Foreword: This volume contains the proceedings of the First International Workshop on Architectures, Concepts and Technologies for Service Oriented Computing (ACT4SOC 2007), held on July 22 in Barcelona, Spain, in conjunction with the Second International Conference on Software and Data Technologies (ICSOFT 2007). The ACT4SOC workshop aims at serving as a forum for researchers and practitioners, from academia and industry, to meet and to discuss the goals, benefits, achievements and challenges of Service Oriented Computing (SOC). SOC has emerged as a helpful paradigm for designing, building and using IT solutions, based on a set of architectural guidelines and concepts referred to as the Service Oriented Architecture (SOA). SOC/SOA can be seen as a next step in the evolution of modular middleware approaches, such as CORBA, DCOM and J2EE. The objective of SOA is to make the development of IT solutions for endusers easier and more cost-effective through the adoption of service orientation. Service orientation has service as its central concept to denote a function independent of its possible implementations and independent of its possible user environments. Moreover, service orientation entails the existence of a distributed computing platform, which supports registration of services, discovery of services, invocation of services, and coordination of services. Hence, this foundation, when underlain with proper technology, contributes to important business objectives, including 'plug-and-play' interoperability through 'loose coupling' and 'technology transparency'. Although SOA is independent of any specific technology or technology platform, its benefits can only be achieved through support from concrete technology. The current technology of choice for realizing SOA is Web services, which comprise practical base standards for service orientation, while building on the popularity of Web technology and ubiquitous Internet standards. The uptake of Web services based SOC is impressive, but Web services still have important limitations, and they are by no way a complete and satisfactory realization of the distributed computing platform for SOC. Many practical and fundamental challenges remain and need to be addressed in order to achieve the full potential of SOC.Among these are quality-of-service, security, semantic interoperability, automatic composition, and business-technology alignment. The goal of this workshop is to focus on the fundamental challenges related to SOC, to discuss what architectural/conceptual foundation is needed, and how this foundation can be supported by new or (extensions of) available technology. Following the ACT4SOC 2007 Call for Papers, 23 paper submissions were received, from which 8 papers were selected for a 30-minutes oral presentation during the workshop and for publication in this proceedings. Each of the submitted papers went through a thorough review process, with at least 3 reviews per paper. Due to the number of reviews and the professionalism of the authors, program committee members and reviewers, I am confident that all selected papers are of high quality. The selected papers are also a good illustration of different topics that are currently under research. They have been grouped in three presentation sessions during the workshop, named "Architectures", "Concepts" and "Technologies". I like to take this opportunity to express my gratitude to all people who contributed to ACT4SOC 2007. My thanks go to the authors, who provided the main content for this workshop, and to the program committee members and reviewers, who provided constructive comments that contributed to the quality of the content. I also like to thank the ICSOFT secretariat, especially Mónica Saramago, for the excellent organizational support. Finally, I appreciate the opportunity given by the ICSOFT chair, Joaquim Filipe, to organize this workshop in conjunction with ICSOFT 2007. I wish all presenters and attendees an interesting and productive workshop, and a pleasant stay in the beautiful and exciting city of Barcelona. (More)
