Research On The Product Data Exchange Based On OWL

With the development of computer technology and the semantic web, along with the economic globalization, the trend of the globalization of manufacturing and network is more and more obvious. Traditional way of product information sharing has been unable to meet the needs of modern enterprise development. The level of the information sharing has been the sharing of data to a knowledge sharing.In this paper, based on STEP standard AP203, exchange of STEP neutral files and OWL is studied, I develope the data conversion system based on OWL, complete the STEP neutral file conversion to the OWL file.The main work accomplished in this paper:(1) This paper expounds the basic principle and structure of STEP standard,studies its content; detailed study the language EXPRESS, the various data types, entities and properties; through the study of information model of AP203 protocol and EXPRESS instantiation, understand the STEP neutral file, and its structure are analyzed.(2) This paper expounds the development of semantic Web languages, and introduces the three child language OWL include: OWL Lite、OWL DL and OWL Full;at the same time this paper introduces the basic elements, OWL grammar and composition and the structure of OWL document are analyzed, and finally introduces the ontology construction tools Protege.(3) Design the framework of the data conversion system based on OWL, and expound the design idea of the whole design system; Detailed build mapping rules between the EXPRESS and OWL, and between STEP and OWL, at the same time establish the mapping relationship between the EXPRESS and OWL, and between STEP and OWL.(4) Data conversion system is developed based on vc + + to achieve the transition of the STEP neutral file to the OWL; and cylinder as an example generated in SolidWorks as a data source, through the data conversion system generate OWL file, and the file is used to detect the semantic, visualization analysis by Protege, the image of the view class and between classes, classes and between individuals and the relationship between the individual and property.
