异构工作流管理系统的互操作性研究

Research of Workflow Interoperability Based on Wf-XML

随着工作流技术不断发展，工作流产品的应用越来越普及，不同企业的工作流系统也越来越多的需要协作，然而目前工作流系统之间的互操作问题没有得到很好的解决，这就成为工作流技术进一步应用的瓶颈，如何实现不同工作流引擎之间的互操作成为急需解决的问题。本文提出了一种基于WebServices、Wf-XML的支持异构工作流管理系统之间互操作模型，其思想是将工作流的对外提供的功能包装为web服务，并使用Wf-XML格式来包装互操作消息，使不同工作流之间能够互相查找工作流服务、解析互操作请求，从而实现服务的互相调用。

With the rapidly development of workflow,the workflow management system becomes more and more popular.But it also brought an application bottleneck of interoperability between workflow management systems,how to achieve interoperate between wfms is an urgent problem.This paper gives a new workflow interoperating model based on Web Services and Wf-XML.The main idea is packaging the external function as web services,and using Wf-XML as interoperating message format,so different workflow systems can search workflow web service and parse the interoperating request,and eventually realize the interoperability.
