Abstract: For networked manufacturing and digital manufacturing, the sharing of the product data among systems is a key problem to be resolved. To realize the sharing, CAD systems must output product data with STEP standard. By translating the STEP files into the corresponding XML neutral documents with the criterions constituted by the ISO, XML Schema library is setup. Thus, the neutral documents can be transferred throughout Internet, so different manufacturing systems can share product data. Verified by a simple example, this reliable way expresses the STEP-based product data with XML, and apply the criterions of the interpreting between STEP and XML.
