Status of RDF in Drupal (November 09) and wrap up of ISWC2009 | OpenSpring

Description

I had the pleasure to give a presentation of the paper " Produce and Consume Linked Data with Drupal! " at ISWC2009 last, and I was very honored we won the Best Semantic Web in Use Paper award!

Contributed modules means they do not get included in the core Drupal package, but people can download them from drupal.org for free and drop them on their server so Drupal core can be extended. These 4 modules work pretty well on Drupal 6, you can get RDF export in RDF/XML, N-Triples, turtle, json. However generating RDFa is not very easy as it requires to patch the CCK on which we rely to generate the content pages and store the various field data. We made sure this would not be a problem in the next version of Drupal (Drupal 7) which is still under development, and due to be released sometime next year. While we were at it, we also worked on porting one of the functionality present in the RDF CCK and Evoc module to Drupal 7 core: the ability to map the data structure to RDF and expose this in RDFa.
