Zhang Zhijun Fan Yushun(Department of Automation,Tsinghua University,Beijing100084)  
Workflow Process Definition Language(WPDL)facilitates the transfers of workflow process definitions between separate workflow products.Normally there is still much work to do to transfer the specific workflow model to WPDL conforming model.CIMFlow is a workflow management system developed by the National CIMS Engineering Research Center.This paper discusses the methods to make CIMFlow model conform to WPDL meta -model.Firstly,the WPDL meta-model,the CIMFlow model,and the differences between them are presented.Then,some improvements and modifica-tions to the WPDL specification are proposed.Finally,the mapping and translating methods of the entities and attributes of the two models are given.
