Resource Description Framework
The Drupal 7 RDF contrib project has now a new home: RDF Extensions (RDFx). The reasons for this move are explained in this issue..

If you are new to RDF, watch this introduction.

RDF is a W3C standard for modeling and sharing distributed knowledge based on a decentralized open-world assumption. Any knowledge about anything can be decomposed into triples (3-tuples) consisting of subject, predicate, and object; essentially, RDF is the lowest common denominator for exchanging data between systems.

This module provides comprehensive RDF functionality and interoperability for the Drupal 6.x platform. For more information, watch the demo video. Be sure to subscribe to the Semantic Web group on to keep up with the latest happenings.

This project is for Drupal 6 only and is no longer maintained, please see RDF Extensions for the active Drupal 7 developments in RDF.

Drupal 6

The RDF module for Drupal 6 requires PHP 5.2 or newer, makes use of the ARC2 library if available, and will integrate with the Views, FeedAPI, Feed Element Mapper, Location, and Services modules if they are installed. For adding SPARQL query support, see the related SPARQL project. Read the introductory posting to learn more about the Drupal 6 version of the RDF module.

Projects that rely on this module as a dependency include Calais, File Framework, FeedAPI RDF and the Relations and DAV APIs and their spin-offs such as File Relations Server.


This project was previously developed and maintained by Arto Bendiken, Miglius Alaburda, Ben Lavender, Frank Febbraro and Jeff Miccolis. Development has previously been in part sponsored by OpenBand and MakaluMedia.
