A Little Note About Microformats
Further proof that things are starting to bubble: small but interesting ideas like microformats pop up out of nowhere (well, for me, at least). As the About page of the eponymous Web site says:Designed for humans first and machines second, microformats are a set of simple, open data formats built upon existing and widely adopted standards.
The key thing is that they are built around XHTML, which is effectively HTML done properly. Examples of microformats that are based on things that may be familiar include hCard, based on the very old vCard, hCalendar, based on the equally venerable iCalendar, moderately old stuff like XHTML Friends Network (XFN), which you stumble across occasionally on the Web, and the inscrutable XOXO (which I've heard of, but never seen brandished in anger).
That's the upside; on the downside, Bill Gates has started talking about it.
