Abstract: To facilitate the interoperations among autonomous, dynamic and semantically inconsistent services in grid environments, an eventdriven service mediation mechanism was proposed to deal with dynamic service matching and interoperation. With the mechanism, business events were treated as the firstclass entities, and the relationships among business events were introduced. Based on business events and their relationships, four service mediation primitives were presented to realize looselycoupled interoperations and data exchanges among services. The core concepts, working principles and interoperation process of the mechanism were discussed by combining a supply chain scenario. Experiments showed that the mechanism could realize the interoperation among services while preserving their independence.
