Abstract

With the frequent changes in recent business and scientific environment, more efficient and effective workflow infrastructure is required. Besides, with increasing emphasis on Service-oriented architecture, service composition becomes a hot topic in workflow research. This paper proposes a novel approach of using ECA rules to realize the workflow modeling and implementation for service composition. First of all, the concept and formalization of ECA rule-based Workflow is presented. Second, an automatic event composition algorithm is developed to ensure the correctness and validness of service composition at design time. Finally, the proposed ECA rule-based approach for service composition is illustrated through a prototype system.
