Abstract: To realize the general representation and network transmission of product data, construct the general feature model, and guarantee the coherence of data format as well as the readability of document structure and access of post-process of product data in the distributed network environment, an STandard for the Exchange of Product model data (STEP)-based feature modeling method was presented by using eXtensible Markup Language (XML). First, based on the analysis of STEP feature framework, the structure product was decomposed, which was mapped to corresponding product features, and an integrated product feature model was constructed. Then，the mapping rules and modeling method of features from EXPRESS to XML representation were discussed, meanwhile, the feature modeling framework was constructed by XML, and XML document parsing process and network resolution were expressed. As a result, the exchange and share of product data in the distributed network environment and the interaction operation of product data among different customers were realized. Furthermore, this method was illustrated by an application case on the platform of IIS.
