基于XML Schema和Web服务的虚拟企业集成框架

虚拟企业(Virtual Enterprise,VE)环境中异地分布的伙伴企业采用不同的平台运行,这造成了VE内部大量异构数据的存在,可以说VE在本质上是一个异构系统的集合体.在异构系统间以STEP(ISO-10303)建模语言--EXPRESS映射的XML Schema作为产品数据交换集,既保证了产品全生命周期中产品数据的一致性又使得基于Internet的跨企业应用集成成为可能.鉴于上述思想,本文提出了一种基于XML Schema的VE集成框架;并且,借助Web服务技术,对CAx和PDM系统间跨企业的集成方式进行了新的探讨:将PDM系统的某些方法(CheckIn/CheckOut等)以Web服务的形式提供给CAx系统.这样,系统间可以XML Schema约束的有效XML数据绑定的SOAP消息进行交互,实现Internet平台上跨企业的地集成.最后以实例加以说明.

A virtual enterprise integration framework based on XML Schema and Web service

In virtual enterprise, geographically distributed partner enterprise use different operation system to run software system(such as CAx/PDM etc.), which cause to a wide variety of heterogeneous data, that is to say, VE is a aggregation of heterogeneous system. STEP mapped XML Schema is used for transaction sets which make a unanimous paradigm in production life cycle and Internet-based crossing-enterprise integration come true. The paper address a VE integration framework based on STEP mapped XML Schema and a new solution for CAx/PDM integration by means of web service technology. So, CAx can invoke PDM web service (ChechIn/CheckOut web method) to exchange product data by interoperation of SOAP message which is band by XML Schema constrained valid XML data. Finally, an example is illustrated to further argumentation.
