RDF in Drupal Screenshot

As work has now started on getting bioclipse.net on Drupal (more on that in a while), it's good to know that Drupal is in to semantic web.

I was wondering what it looks like (since I have not had time to play with it), and to me, this screenshot was clarifying, showing how you can map fields (core fields, or your own custom ones) to rdf types (In drupal you can create both custom fields, and custom content types, which contain many fields).

Also useful might be the roadmap for RDFa in Drupal 7 (the upcoming version).
