Query Processing for RDF data Using XML Repository

Abstract

The Semantic Web, which represents a web of knowledge, offers us new opportunities to search for knowledge and information. To harvest such search power requires robust and scalable data repositories that can store RDF data. Most of the existing RDF storage techniques rely on relation model and relational database technologies for these tasks. The mis-match between the graph model of the RDF data and the rigid 2D tables of relational model jeopardizes the scalability of such repositories and frequently renders a repository inefficient for some types of data and queries. In this paper, we propose a system that can store RDF data in the XML repository. This system serializes RDF data into RDF/XML and then maps into a XML document. We discuss the basic idea of serializing RDF data into RDF/XML and then mapping of RDF/XML to XML document.
