Research on Product Data Exchange Technology Based on XML Language and STEP Standard in Collaborative Design
In Web based collaborative manufacturing environment,in order to solve the information exchange problem caused by heterogeneous CAD systems located in different places,and to realize collaborative design among cooperative members,there's in need to develop uniform product information integration specification.Based on the comparison of different exchange technologies,the paper put forward a method by using STEP as neutral mechanism and applying XML as the carrier for product information model transmission through Internet.Regulations and methods for mapping from EXPRESS to XML were discussed in the paper.Research and exploration on XML/STEP based product data exchange,data sharing and information integration under Web based collaborative manufacturing environment were done in the paper.
