A Model Driven Approach to Defining Workflow Process
一种模型驱动的工作流过程定义途径

Interoperability, reusability, portability and productivity are the real challenges for traditional workflow management system, MDA is an approach to meeting the challenges mentioned above. In the research area of model driven workflow management system, workflow model is the very core of the subject. As a start, extended workflow metamodel and Petri net based formal workflow model procedure net are introduced. And then, according to MDA and given workflow model, a model driven framework is proposed for rapidly building workflow management system. Finally, one of the key steps in the framework, i.e. transformation (process and rules)from EPC based process CIM to procedure net based process PIM, is discussed in detail, and E-PNML specification for process PIM is given.
