R2RML: RDB to RDF Mapping Language

Abstract:

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.

First draft from the RDB2RDF working group.

Questions:

  1. Select a table from two (or three) databases in a common area with different schemas.
  2. Convert the tables using the latest version of this proposal to RDF datasets.
  3. On what basis would you integrate the resulting RDF datasets into a single RDF dataset?

  1. For the record, Ontopia already has this, in the DB2TM module, with support for synchronization.
