A Direct Mapping of Relational Data to RDF

Tuesday, August 14th, 2012

A Direct Mapping of Relational Data to RDF from the RDB2RDF Working Group.

From the news:

The need to share data with collaborators motivates custodians and users of relational databases (RDB) to expose relational data on the Web of Data. This document defines a direct mapping from relational data to RDF. This definition provides extension points for refinements within and outside of this document. Comments are welcome through 15 September. (emphasis added)

R2RML: RDB to RDF Mapping Language

Tuesday, August 14th, 2012

R2RML: RDB to RDF Mapping Language from the RDB2RDF Working Group.

From the news:

This document describes R2RML, a language for expressing customized mappings from relational databases to RDF datasets. 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 and written down in Turtle syntax. R2RML enables different types of mapping implementations. Processors could, for example, offer a virtual SPARQL endpoint over the mapped relational data, or generate RDF dumps, or offer a Linked Data interface. Comments are welcome through 15 September.
