GAIA—An OWL-based Generic RDF Instance Generator

Keywords

OWL, RDF, Semantic Web, Ontology, Taxonomy, Instances generation.

Synopsis

An RDF (Resource Description Framework) instance generator produces RDF triples by complying with an ontology that defines classes, subclasses, relations, and constraints. There are many instance generators which rely on Web Ontology Language (OWL) meaning that these generators can read only the ontologies which are written in OWL. However, the existing generators are locked-in to a specific ontology, which means the generators can read only a specific ontology. For instance, the LUBM generator can read only the LUBM ontology, which is clearly a limitation as it is not able to read any other ontology such as biomodel ontology. This promotes the need for a generic RDF instance generator that is able to read and parse any ontology written in OWL. GAIA is a generic RDF instance generator. With this tool, users can use their own ontology to generate ABoxes of TBox-consistent RDF triples according to their specific needs.
