Abstract: This paper presents a design and implementation of a novel OWL-based RDF instance generator. Technologies are very often experimented to verify their behaviour or suitability for a certain usage. The experimenters require data for conducting experiments. The real-world data may not be easily available or accessible, in many cases. Therefore, synthetic data are used. There are solutions for generating datasets which consist of RDF triples. However, they are locked-in to specific ontologies. This, in our view, is a critical limitation, since it is not a flexible approach. In this paper, we present a generic RDF data generator called GAIA which allows users to generate RDF triples by conforming to any ontology. GAIA is built on an in-memory architecture and it relies on parallelisation techniques which guarantee high-performance. The results of experiments show that GAIA performs reasonably well with large-scale ontologies. In addition, it can handle large-scale ontologies such as NCBI.
