Resource Description Framework (RDF)

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, read the introductory posting or watch the demo video. Be sure to subscribe to the Semantic Web group on groups.drupal.org to keep up with the latest happenings.

Status of this module

Newcomers willing to try the RDF module should be aware that the Drupal 6 version of this module is not actively maintained, and that all our efforts are going towards transiting to Drupal 7. Therefore, if possible, you are strongly encouraged to hold on for a couple of weeks and wait for the Drupal 7 version of this module which will be more straight forward to use, and will leverage Drupal 7 core's RDF mappings and RDFa markup.

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.

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.
