rel microformats

Remember the rel attribute from earlier? That attribute is often used in microformats,
and the usage is generally very simple. The rel-license format, for instance, looks like this:
<a rel="license" href="http://creativecommons.ca
/licenses/by-nc-sa/2.5/">
Creative Commons License</a>
By including a rel attribute with a value of license in the anchor tag, you can indicate
that the destination of the hyperlink is a license for the content contained on the current
page. The example I’m using is from my own design blog Unfortunately Paul, where the
content has been made available under a “Creative Commons Attribution-NonCommercial-
ShareAlike 2.5 License,” which means that people are free to copy, distribute, and display
my published entries and to make derivative works so long as I’m credited, it’s for nonprofit
purposes, and any derivations are released under the same license. Creative
Commons is an organization that provides a variety of “some rights reserved” copyright
licenses, allowing content authors to release their content into the wild but retain some
level of copyright.
