The Linked Data initiative brought new opportunities for building the next generation of Web applications. However, the full potential of linked data depends on how easy it is to transform data stored in relational databases into RDF triples. Recently, the W3C RDB2RDF Working Group proposed a mapping language, called R2RML, to specify mappings between relational schemas and RDF vocabularies. However, the specification of R2RML mappings is not an easy task. This paper therefore proposes a strategy to simplify the specification of R2RML mappings. The paper first introduces correspondence assertions, which provide a convenient way to manually model mappings between relational schemas and RDF vocabularies. Then, the paper describes a method to automatically generate R2RML mappings from the correspondence assertions.
