D2R MAP - A database to RDF mapping language 论文

摘要

The vision of the Semantic Web is to give data on the web a welldefined meaning by representing it in RDF and linking it to commonly accepted ontologies. Most formatted data today is stored in relational databases. To be able to use this data on the Semantic Web, we need a flexible but easy to use mechanism to map relational data into RDF. The poster presents D2R MAP, a declarative language to describe mappings between relational database schemata and OWL ontologies.
