RDFa helps bloggers and website authors make their web pages smarter by adding computer-readable information to a site. Details about yourself, events, places, books, and music are just some of the "things" you can describe using RDFa. By adding RDFa to your website or blog, you help computers interact with your website in a way that is more helpful to people visiting your site. RDFa makes web browsers smarter by giving people more options when viewing a web page, such as adding you to their address book, adding an event to their calendar, getting directions to a place described by RDFa, or searching online bookstores for a book marked up using RDFa. There are many possibilities with RDFa and this community is dedicated to RDFa education, development, and advocacy.

I am currently working on a Google Summer of Code project to make it easier to bring RDF data into your Drupal site and use it in meaningful ways.

I also have contributed screencasts that give an introduction to Drupal 7.

here were presentations from the BBC about their Wildlife Finder, which pulls a lot of content and data from sources like Wikipedia and the WWF, and from Tom Heath of Talis talking about we need to move towards building applications for the 'web of things' rather than for the current 'web of documents'. Lin Clark gave an overview of how the next version of the Drupal CMS comes with RDFa capabilities built in to it.
