摘　　要：针对工作流流程定义文件之间需要相互转换的问题,提出了一种基于规则库的流程定义文件转换方法。该方法首先通过建立映射规则库来存储不同流程定义语言间相互转换的规则,然后在转换过程中动态查找规则库,获取当前流程定义转换所需要的规则,最后用获取的规则初始化转换引擎以实现流程定义文件的转换。采用上述方法建立了从XPDL(Xml process definition language)到BPEL(business process execution language)及BPEL到XPDL之间的转换规则库,运用该规则库完成了实例的相互转换。实验结果表明了该转换方法的可行性和有效性。Aiming at the problems of mutual transformation between the workflow process definition documents, a transformation method of process definition document based on rule data base is proposed. Firstly, the corresponding mapping rule data base is built to store the needing rules of different process definition languages. Secondly, the rule data base is looked up dynamically to find out the useful rules during the transformation process, and finally the transformation engine is initialized by the acquired rules to achieve the transformation of process. The transformation rule data bases are created from XPDL to BPEL and BPEL to XPDL to accomplish the transformation of instance. The result shows that the method proposed in the paper is feasibility and valid.
