R2RML, a W3C Recommendation, is a language for expressing customized mappings from relational databases to RDF data sets. Such mappings provide the ability to view existing relational data in the RDF data model, expressed in a structure and target vocabulary of the mapping author's choice. R2RML mappings are themselves RDF graphs written in Turtle syntax. R2RML is becoming the generic standard adopted by most vendors of tools mapping relational data to RDF, enabling the interoperability of R2RML scripts, whether created with such tools or by hand. This page discusses how to use R2RML specifically with Virtuoso.
