Product Data Sharing and Integration Technology in Network Supported Collaborative Design

In network supported collaborative design, the sharing and integration of multi-site and heterogeneous data is one of the key problems. The flexible data model and open access characteristics of XML can provide powerful support for the product data sharing and integration. This paper presents the XML-based solution of product data sharing and integration. On the basis of summarizing STEP and the XML technology characteristic respectively, the technology of the integration of XML language and STEP standard to express product is analyzed. Aiming at the related question in data transmission and exchange using XML, such as data parse, data storage and data query, this paper all gives the detailed explanation.
