Antidot apporte sa contribution au développement du Web de Données en ouvrant son implémentation des recommandations R2RML et DirectMapping du W3C. Antidot est impliqué depuis de nombreuses années dans la mise en œuvre opérationnelle des recommandations et standards publiés par le W3C comme RDF , OWL , SKOS ou SPARQL . Ne se cantonnant pas à une approche purement académique, et fort de sa position sur le marché des solutions d’accès à l’information , Antidot a été l’un des premiers éditeurs de logiciels à confronter ces nouveaux outils du Web Sémantique aux besoins et contraintes de grands projets industriels .

R2RML: RDB to RDF Mapping Language
1 Introduction Relational databases proliferate both because of their efficiency and their precise definitions, allowing for tools like SQL [SQLFN] to manipulate and examine the contents predictably and efficiently. Resource Description Framework (RDF) [RDF-concepts] is a data format based on a web-scalable architecture for identification and interpretation of terms. This document defines a mapping from relational representation to an RDF representation. Strategies for mapping relational data to RDF abound.
A Direct Mapping of Relational Data to RDF
Resource Description Framework
From Semantic Web Standards Overview RDF is a standard model for data interchange on the Web. RDF has features that facilitate data merging even if the underlying schemas differ, and it specifically supports the evolution of schemas over time without requiring all the data consumers to be changed. RDF extends the linking structure of the Web to use URIs to name the relationship between things as well as the two ends of the link (this is usually referred to as a “triple”). Using this simple model, it allows structured and semi-structured data to be mixed, exposed, and shared across different applications.
