One particularly interesting use case that seems to keep popping up is that of understanding what a page represents.

This page is for collecting research, ideas, and brainstorms about using microformats to represent what a page is (or is about).

microformats do a good job of allowing authors to easily markup various semantics in pages such as people, events, reviews etc., however, there are only a few examples (XFN, rel-me, representative-hcard) of using microformats to designate what a whole page means or represents.

microformat root class on html or body

One simple technique that could work for all microformats is to put the root class name of the microformat on the <html> (permitted in HTML5), or if not, then the <body> element.

A page that represents an event:

<!DOCTYPE html>
<html class="vevent">
...
</html>

A page that represents a review:

<body class="hreview">
...
</body>

This is a simple/easy rule to remember for publishers.

For processors/parsers, the rule is simple as well:

  • ... but a lot of publishing platforms (i.e. blog engines, CMSes) would make this pretty difficult in practice. TobyInk 08:06, 17 July 2010 (UTC)
    • Could you provide concrete examples of specific blog engines or CMSes that you've had problems with? The evidence shows otherwise. See cms etc. for blog engines, CMSes that support microformats now. Tantek 20:27, 17 July 2010 (UTC)
