First International Workshop on Engineering Service Compositions |

THEME
The emerging paradigm of service-oriented computing (SOC) introduces ground-breaking concepts for distributed- and e-business processing that are radically changing the way software applications are designed, architected, delivered and consumed. Services, which constitute the heart of SOC, are autonomous platform-independent computational elements that can be described, published, discovered and accessed over the Web using standard protocols. Service-oriented architectures (SOA) leverage the foundational capabilities of computational service models to provide technological as well as conceptual frameworks for a new class of cooperative business applications: agile networks of collaborating business applications distributed within and across organisational boundaries. Consequently, SOA not only includes software technologies to aggregate atomic services into composite services (a.k.a. service composition) but also the software engineering methodology to turn composite services into cooperative business applications (a.k.a. service engineering).
In fact, service composition and software engineering are highly interrelated. Service composition not only developed towards the major software technology approach for composing multiple coarse-grained applications over the Web but also originated pioneering concepts such as orchestration and choreography. Such concepts introduce significantly different ways of managing business connectivity, thus making a strong impact on application semantics and vice versa. In order to guarantee a certain quality level of SOA-based cooperative business applications with respect to functional and non-functional requirements, software engineers have to take into account the impacts of service composition models. In the emerging discipline of service engineering, that generally benefits from former research on component- and aspect-oriented software engineering methodologies, there are already promising results on novel conceptual and technological tools to support the development processes of cooperative business applications. However, such tools need to be increasingly aligned with service composition technology.
Still, joint approaches on engineering service compositions face several open problems and challenges. Concerning the technology side there is still neither an agreement on service composition models and languages nor on their scope of application; let alone experiences on mission critical operation. As regards methodology , reference architectures of service-oriented cooperative information systems taking into account particularities of the service composition lifecycles are just at the beginning. This is just to name a few of the challenges.
Accordingly, the workshop is intended to bring together experts from service composition technology and service engineering methodology; researchers and practitioners from industry and academia. It is meant to foster discussions about problems and challenges that particularly arise during the practical combination of both fields of expertise for the realisation of service-based, cooperative business information systems.
