RDFa

Do you write HTML? You’ve just heard that Google now supports RDFa and you want to know where to start? Our own Steven Pemberton just published a fantastic RDFa introduction for HTML authors:

RDFa is a thin layer of markup you can add to your web pages that makes them understandable for machines as well as people. You could describe it as a CSS for meaning. By adding it, browsers, search engines, and other software can understand more about the pages, and in so doing offer more services or better results for the user. For instance, if a browser knows that a page is about an event such as a conference, it can offer to add it to your calendar, show it on a map, locate hotels or flights, or any number of other things.
