Abstract: This paper presentes an XML-based workflow definition language named XML-WfPDL to describe the workflow process model,deriving from the advantages of the XPDL of WfMC and XML. This language separates workflow process definition from workflow executionengine, so it may make the workflow definition language flexible enough to adapt to web and the heterogeneous application environment. And then,it also introduces design idea, main concept and related realization technology of XML-WfPDL. At last, it gives an example of a networkexamination and approval system based on XML-WfPDL.

摘要： 针对目前工作流过程描述语言灵活性不够的问题,从工作流系统的Web化以及适应异构应用环境角度出发,将工作流过程定义与工作流执行相分离,继承了WfMC的XPDL标准和XML的优点,提出了一种基于XML的工作流定义语言XML-WfPDL,并介绍了语言的设计思想、主要概念及实现的相关技术。最后,给出了利用该语言开发实现的一个网上审批软件系统。
