Microformats
From semanticweb.org
Microformats are markup that allow expression of semantics in an HTML (or XHTML) web page. Programs can extract meaning from a standard web page that is marked up with microformats.
Existing XHTML (and HTML) standards allow for semantics to be embedded and encoded within them. This is done using specific HTML attributes:
- class
- rel
- rev (deprecated in microformats, apart from a few grand-fathered uses)
Adding microformats to a regular HTML web page allows machines to process HTML text and to possibly load data into remote databases. This would allow programs such as web crawlers to find items such as contact information, events, and reviews on web pages.
[edit] Example
For example, consider the hCard contact information microformat:
