A Framework for Workflow Process Definition Transformation Based on Meta-Model

The current tools for process definition transformation only support fixed conversions from one definition language to another. A model transformation framework, which is able to achieve mutual conversions among a variety of process definition languages and is based on meta-model, is proposed from the common perspective of the mapping and transferring of models. The framework uses dynamic mapping rules set between the different meta-models as the basis for the transformation, and exerts transformation engine to accomplish the conversion. A grammar structure of the rules and a transformation algorithm are given and a framework of the prototype for workflow process definition transformation based on meta-model is designed and implemented. In order to validate this new transformation framework, a transformation from BPEL model to XPDL model is selected as an example, which gets the correct result.
