摘　　要：为解决企业制造过程信息的描述和交互问题,提出了一种基于可扩展标记语言(XML)的过程描述元模型。在该模型中,定义了基于过程描述语言(PSL)本体的语义映射规则及映射的具体过程,对过程描述语言本体进行了语义分析,实现了对过程信息的语义层次描述;借助可扩展标记语言的语法结构,建立基于可扩展标记语言的过程描述语言核心元素的描述规则,并作为过程信息语法层次描述的统一标准,实现过程信息在语法层次的信息转换。最后,通过具体的可选工艺信息描述实例,验证了该模型及实现方法的有效性和可行性。To improve the description and interaction of the manufacturing process information across enterprises, a meta-model based on Extended Markup Language （XML） for process description was proposed. To realize the semantic description of process information, semantic mapping rule and procedure based on Process Specification Language （PSL） ontology was defined and the semantic of PSL ontology was analyzed. To realize the syntactic description of process information and information exchange, a description rule for PSL core based on XML was established. Finally, an example of alternative routing description was provided to illustrate the validity and feasibility.
