Storage structure and management skills for RDF schema versioning in RDB environment

Abstract

With the growing use of Internet information exchange, interest about semantic Web is rising for satisfying the user's various requests. Ontology is a basic building concept for semantic Web and ontology language such as RDF/RDF schema is a basic tool for constructing ontology system. One of the major points when constructing ontology with RDF/RDF schema is versioning because ontology knowledge is not static but change as times go by. Therefore, ontology systems should provide versioning skills which reflect changes in domain, changes of data concept, and changes of relations between data resources. This paper discusses the problems of RDF schema versioning and provide storage structure and management skills for RDF schema versioning in RDB environment. We introduce version graph and transitivity rule which is used for version selection for some data. Finally, we introduce a storage structure for implementing the versioning scheme
