Semantic Web

Based on my comment to <http://buytaert.net/drupal-the-semantic-web-and-search">Dries Buyteart's Drupal, the semantic web and search, which ended with "I can has semweb in Drupal core?"

RDF has a very long, if quiet, history in Drupal core. In the year 2000, May 18, in what I think is the first commit to the still-going CVS repository that holds the Drupal project — back when Drupal was called drop — Dries Buytaert included a file called rdf.php.
