Design of workflow model interoperation based on rule
一种基于规则的工作流模型互操作的实现方法

In this paper, we mainly analyzed the structure and feature of workflow language, XML Process Definition Language (XPDL) and Business Process Execution Language For Web Services (BPEL),and then designed a strategy of workflow model interoperation in two aspects, control flow and data flow of workflow. Based on this idea, we developed a transformation algorithm and implemented this transformation by a Java-based open source rule engine named drools.
