Welcome to the RDFa Handbook.

Over the coming weeks we'll be continuing on from the two introductory articles which first appeared on A List Apart in June and July, 2009.

The articles are Introduction to RDFa and Introduction to RDFa II, and it's worth reading them before continuing with the articles here.

Just over a year ago I wrote a blog post that showed how to create a FOAF profile on a web page, using RDFa. The idea was not only to show how easy it was to do in terms of the markup, but also to illustrate that once you are able to publish RDF via a web page, you need nothing more than a blog page to join the semantic web.

This blog post updates that old post, by first adding some guidance on how to check your document (using the Ubiquity RDFa parser), and then proceeding to add more features to your blog page.
