R2RML 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.
