【Abstract】 Analyzed the mechanism and its underlying problems of the traditional implementation methods for STEP data exchange. Discussed the feasibility and basic methods of the XML representation as a new implementation method for STEP. Explored the mapping methods of the meta-model components of EXPRESS language to the corresponding XML constructs.
