Improving the interoperability of mechanical design data using XML and ontology

XML과 온톨로지를 이용한 공학 설계 데이터의 상호운용성 증진에 관한 연구

As the complexity of engineering design environment has increased, it is difficult to exchange design data among design support systems. The purpose of this paper is to develop the XML-based Generalized Mechanical Data Exchange Formats(GMDEF) independent of specific mechanical element and improve the interoperability of them using ontology, in order to integrate diverse design data and facilitate communication between design support systems. GMDEF consists of PartDoc and AssemblyDoc. PartDoc represents the information of a single part. AssemblyDoc represents the relation of parts constituting an assembly. GMDEF is validated by GMDEF Schema. GMDEF Schema consists of separated XML Schemas and has flexible architecture to facilitate extension. We apply ontology to GMDEF Schema to share and reuse vocabularies of specific mechanical elements.
