Abstract: The transformation rules based on meta-class mapping were used in most existing process transformation approaches,which was limited to deal with process model transformation for huge differences between process modeling languages in modeling notation and syntactic.To solve this problem,a control-flow pattern based transformation framework was proposed,which included a framework of control-flow pattern definition as the transformation core.The transformation rule from source language to target language could be auto generated by establishing the mapping relationship with transformation core respectively.A process model transformation tool was developed based on the transformation framework,and  the transformation from Business Process Modeling Notation (BPMN) to Yet Another Workflow Language (YAWL) was used to validate this transformation tool.

Key words: process model, model transformation, control-flow pattern, transformation rule
