MOVE: A Generic Service Composition Framework for Service Oriented Architectures

Abstract

One main requirement for virtual organizations are shortterm collaborations between business partners to provide efficient and individualized services to customers. The MOVE project targets at a methodology and a software framework to support such flexible collaborations based on process oriented design and communication by Web services. MOVEs framework supports the graphical design and verification of business processes, the execution and supervision of processes in transaction-oriented environment, and the dynamic composition and optimization of processes. A business process may be composed from a set of Web services, deployed itself as Web service and executed in the framework. The automated composition of processes from Web services is implemented with methods from AI-planning. We map Web service descriptions, domain knowledge and customer requests into PDDL, an input language of AI-planners. We show the performance of our program with one typical AI planning system and give some implementation details. Finally we conclude with some remarks about further research.
