RDFa

Dries Buytaert has a blog posting on Drupal, the semantic web and search.

Creating a new job posting on a Drupal site would generate RDFa that semantic search engines like Yahoo!’s SearchMonkey would pick up and the job would be included in their world-wide job database.

Technologies like this disintermediate so many existing websites and organizations that it makes my head spin. It is too great an opportunity for us to pass up on. By adding semantic technology to Drupal core, I think we can make a notable contribution to the future of the web.

Exactly!

Today the Semantic Web Deployment Working Group and the XHTML2 Working Group published the W3C Recommendation RDFa in XHTML: Syntax and Processing. This specification allows publishers to express structured data on the Web within XHTML. This allows tools to read it, enabling a new world of user functionality, allowing users to transfer structured data between applications and web sites, and allowing browsing applications to improve the user experience. For those looking for an introduction to the use of RDFa and some real-world examples, please consult the updated RDFa Primer. [W3C link]
