Nowadays, ontologies are used in several research domains by offering the means to describe and represent concepts of information sources Therefore, several approaches and systems storing ontologies and their instances in the same repository (database) have been proposed As a consequence, defining a query language to support ontology-based database (OBDB) becomes a challenge for the database community In this paper, we present OntoQL, an ontology query language for OBDBs Firstly, we present formally the OBDB data model supported by this language Secondly, an overview of the algebra defining the semantics of operators used in OntoQL is described Several query examples showing the interest of this language compared to traditional database query languages are given along this paper Finally, we present a prototype of the implementation of OntoQL.
