Abstract: To avoid switching troubles among various digitizing systems, the conception of interoperation between 3D CAD system and other digitizing systems was proposed. To deal with differences existing in various fields, platforms and domains, the hierarchy of shared ontology and local ontology was designed. The invoking functions of the specific platform was encapsulated through local ontology, and the aggregation of interoperation functions in certain discipline was described through shared ontology. As an example for the interoperability between 3D CAD system and Product Data Management (PDM) system, interoperation functions in different domain were encapsulated by Web service. The eXtensible Stylesheet Language Transformation (XSLT) technology was introduced to implement the transformation among the assembly structure trees under different PDM platforms. The proposed method could be spread to realize the interoperation among digital systems under network environment. Finally, an application example of interoperation in the digital systems integration was given.
