XHTML Friends Network

XHTML Friends Network (XFN) is an HTML microformat developed by Global Multimedia Protocols Group that provides a simple way to represent human relationships using links. XFN enables web authors to indicate relationships to the people in their blogrolls by adding one or more keywords as the 'rel' attribute to their links. XFN was the first microformat.

Example

A colleague of Jimmy Example could indicate that relationship by publishing a link on their site like this:

<a href="http://jimmy.examples.com/" rel="colleague">Jimmy Example</a>
