Rule-based business process modelling and enactment

A business process model is called rule-based if the logic of its control flow, data flow and resource allocation is declaratively expressed by means of business rules. Business rules are recognised as powerful representation forms that can potentially define the semantics of business process models and business vocabulary. To date, however, there is little consensus and fragmentary knowledge about the precise relationship between these elements of business modelling. In this article, we develop a first-version metamodel that is to be used as a foundation in integrating and developing existing and new forms of rule-based business process modelling. In addition, we show how rule-based process models can be brought to execution in the context of service-oriented architecture.
