Mapping a Relational Database into a RDF Repository

Lately, we hear more and more about Semantic Web and the benefits that it brings to the current Web. But just a few companies are adopting solutions based on semantic web technologies, one reason being that their currently information technology systems are generally based on data stored in relational databases. Replicating a relational database, only with the public information, in a RDF repository, would require additional efforts for the company. This paper presents a solution for mapping a relational database, used to manage the human resources of a company, into a RDF repository, which offers portability and easy integration with other knowledge bases and which can be useful to manage public information about employees. Our approach also highlights the integration of the resulting ontology with PHP to provide a user interface.
