【摘要】 文章开始首先综述了产品数据管理(PDM)的发展状况及XML的发展概况，并指出了以PDM为企业信息集成框架，将XML应用于企业信息集成中的思想。 接下来概括地介绍了PDM技术的起源、发展、功能及前景等和XML的相关标准，如DTD、Schema、XSL、XLL等。 在企业信息集成的过程中，需要应用STEP标准进行企业产品数据的信息建模和产品描述工作，因此比较详尽地介绍了STEP标准的相关内容，尤其是以EXPRESS语言进行产品信息建模的有关内容；并详细地介绍了将XML与STEP相结合的新技术、新标准，将由EXPRESS语言所描述的schema映射为XML的DTD/Schema，实现STEP标准的XML实现方式。 XML在数据交换领域有着很强的优势。本文较为详尽地从XML与数据库、XML传输协议的选取和XML传输安全性问题三个方面介绍了XML在数据交换领域中应用的特点。 在ISO10303标准及XML研究的基础上，以PDM作为企业信息集成的框架，并对该框架的基本架构提出新的基于XML的三层结构设想；同时提出了一种基于XML和STEP的新的模型以给出了解决企业间异构PDM之间的信息集成的新思路；最后尝试建立了一种描述企业产品信息特征的特征标记语言FML作为共享信息模型，为确保企业间和企业内能够实现基于Internet/Intranet的协同工作，实现真正意义上的企业信息集成探索了一个可行的方向。 最后给出一个小例子，该例由XML编制，并配合一定的样式表，目的是显示XML在描述产品信息特征方面所具有的巨大潜力。更多还原

【Abstract】 An overview of the development of Product Data Management (PDM)and the status of XML (extensible Markup Language) are given in this article firstly. Then the author put forward a thought that PDM is regarded as the frame of enterprise information integration and the XML is applied into enterprise information integration.Then the article gives a brief account of the related contents of PDM ,such as origination, development, function and perspective, and the related standard of XML, for example, DTD (Document Type Definition ), Schema, XSL (extensible Stylesheet Language) andXLL (XML Link Language) .In the Process of enterprise information integration, STEP is taken in the modeling of enterprise product data and the representation of product. So the related content of STEP has been presented in details, as well as the related content of EXPRESS language which is used to product information modeling has been done. The new standard and new technology of the combination of XML and STEP also have been introduced in details in this article. The schema which is represented by EXPRESS language is mapped into XML DTD/Schema so as to bring about the XML implementation methods of STEP standard.XML has a great advantage in the domain of data exchanging. This article represents the relation of XML and database, the selection of XML transmission protocols and the transmission security of XML.After researching the standard of IS010303 and XML , PDM is selected as the frame of enterprise information integration .Then a new assumption of three-layer structure based on XML is described which is about the basic structure of PDM. The author gives a new model based on XML and STEP to solve the information integration of PDM between different enterprises. Meanwhile, as a sharing information model, the Feature Markup Language (FML) which is a language describing the features of enterprise product is suggested to implement the real enterprise information integration and real synergetic cooperation inside enterprise or between enterprises.At last, a small instance is given to display the great capability of XML in the domain of representing product information feature.更多还原
