摘要
PSL是美国国家标准技术研究所(NIST)提出的一种制造业过程信息描述的标准。随着可扩展标记语言XML技术的日益成熟 ,采用XML进行过程信息集成已经成为一种必然趋势。NIST提出了一种从PSL向XML映射的层次描述法。本文在对该方法进行研究的基础上 。
PSL is an interlingua for description of manufacturing process information,which is presented by NIST.With the XML technology being increasingly developed,the process information integration by XML becomes a necessary trend in future.NIST presents the methology for mapping the PSL semantic concept to XML.In this paper a process description entity relation method that separates the activities from their relations is proposed.
