【摘要】 在工作流管理系统中,过程模型信息的交换是通过过程建模语言来实现的。不同的过程模型由其专有语言来定义,它们的表达方式可作为选择建模语言的基准。该文首先介绍现已存在的工作流过程建模语言的分类,然后针对其中的一类,着重对两个比较典型的过程定义语言规范进行了分析和比较。更多还原

【Abstract】 In Workflow Management System,the exchange of process models is implemented by languages for the mod-eling of processes.Different process models are defined by their special languages.Their expressiveness can serve as a benchmark for the selection of an application specific modeling language.This paper first introduces the classification of the existing languages for workflow process modeling,then analyses and compares two typical approaches of process defi-nition languages,which are IPO-based languages.更多还原
