Product Model Data Exchange Technology of Heterogeneous Systems in Collaborative Design Environment

The network design based on internet/intranet among cooperative enterprises is a hot topic nowadays, and information exchange is one of the key issues of the collaborative design among heterogeneous systems in the field of network manufacturing. Compared with the existing technologies on collaborative design, the paper mainly focuses on the representation of product model data using XML. The collaborative work mechanism based on STEP is presented. According to AP203, the rules mapping EXPRESS into XML under OSEB is then described. Finally, XML_DTD is generated by using the above rules. The mechanism proposed in our paper can be explored to product model data exchange and integration among heterogeneous systems.
