Microformats Cheat Sheet

Microformats allow us to add more information to our documents on the web, embedding semantic data in web pages that can then be parsed and used in other applications. This reference sheet contains an overview of the most often used microformats.

Note: It turns out there is actually already a rather nice Microformats Cheat Sheet available (in PDF), by Brian Suda. That'll teach me to search for other cheat sheets before starting work on mine!

The Microformats cheat sheet is designed to be printed on an A4 sheet of paper and live by a designer or developer's desk, to make life a bit easier. A description of what is on the cheat sheet follows, or if you are impatient, you can go straight to the full size Microformats cheat sheet.

Further information on Microformats and their specifications can be found at
