Ultrawrap is an automatic wrapping system that synthesizes an OWL ontology from the database’s SQL schema and provides SPARQL query services for legacy relational databases. The system intentionally defines triples by using SQL view statements. The benefits of this organization include, the virtualization of the triple table assures real-time consistency between relational and semantic accesses to the database and the existing SQL optimizer implements the most challenging aspects of rewriting SPARQL to equivalent queries on the relational representation of the data. Initial experiments are auspicious.
