摘要
首先介绍了工作流和XML过程定义语言(XPDL),并提出了XPDL在实际使用过程中的不足之处。对XPDL进行了一定的改进,提出一种基于模板的过程定义语言,包括对该语言的元模型的介绍、该语言如何在XPDL的基础上将流程数据和业务数据相分离,从而实现可重用性和可扩展性。最后,利用该语言实现了一个进行过程定义的工具。
By presenting the concept of workflow and XML Process Definition Language （XPDL）, this paper listed some drawbacks of XPDL in practice. In addition, the XPDL was improved, and another Process Definition Language based on template which had more practical value was put forward. What＇s more, the meta medel of the language and the way of separating the process data and business data were explained in order to acquire the reusability and expansibility. At last, a process definition tool using it was implemented.
