[foaf-dev] RDF/RDFa now part of Drupal core

Be helpful if there was a drupal "consumer" plugin, allowing a convincing demo. i.e. One drupal site pulls pages on an RSS feed from another, parsing the RDFa on each page in the feed, and generates new HTML bounced on its own RDFS data source merging (say). Perhaps the consumer then mints its own RSS feed of its _re-generated_ pages.

Subject: [foaf-dev] RDF/RDFa now part of Drupal core
After several months of research, coding, sprints and patch reviews, the main RDF patch has been committed to Drupal core! (Thanks Dries!) This introduces a basic RDF API which maps the Drupal data structure to RDF. These mappings are then automatically exported as RDFa throughout the site.
To give you a sneak preview of the code it generates, I've put up a Drupal 7 site at http://drupalrdf.openspring.net/ for testing purposes. We still have some bugs to fix but the bulk of it is working. I'm hoping to get feedback from the RDF community about the RDFa it generates. Please try it with your favorite RDFa parser and report any bug you encounter. You will find some dummy RDF properties/classes sometimes but we'll fix them soon. Note that the RDF mappings are fairly independent from the the actual API since the mapping definitions are centralized  and are not hardcoded in the HTML (hereby allowing exports in other RDF serialization formats).

Drupal 7 is still in development phase. The first beta releases should come out in the coming months, and the final release in the new year. Our priority is to fix all remaining bugs  and then agree on the best mappings which will come pre-installed in core. I will send more emails on specific issues, so if you're interested make sure to subscribe to foaf-dev at lists.foaf-project.org<mailto:foaf-dev at lists.foaf-project.org>, sioc-dev at googlegroups.com<mailto:sioc-dev at googlegroups.com> and public-rdf-in-xhtml-tf at w3.org<mailto:public-rdf-in-xhtml-tf at w3.org>.
For those attending ISWC next week, I'll present the research work which was used to build RDF in Drupal core, see paper . See you on Tuesday afternoon in the Semantic Web In Use Track!
