One of the challenges of the semantic Web is to integrate the information already available on the standard Web, usually stored in relational databases. The authors propose in this paper a transformation process from existing relational database schema defined by a set of tables into OWL ontologies using XSLT. This process allows them to mapping some constraints on columns such as primary key, foreign key, unique, not null. Their approach start by translate the database schema into a XML document validate by a suitable XML schema.
