A methodology for dynamic service compositions based on an event-driven approach

In dynamic environments, cross-company service compositions are required to be reactive and adaptable in a timely manner. Complementing the service-oriented paradigm by an event-driven approach provides suitable means for obtaining adequate dynamic behavior of service compositions. Hence, they are enabled to react on changing situations represented by relation patterns of detected external and internal events. Our paper introduces a business-oriented methodology for the modeling of executable dynamic service compositions resting upon BPMN (business process model and notation) in the recent version 2.0 and model-driven development of complex event processing (CEP) rules in a top-down manner. Our methodology is supported by the prototype of a web-based modeling tool.
