Draft Specification 2005-02-06
RelLicense is one of several MicroFormats. By adding rel="license" to a hyperlink, a page indicates that the destination of that hyperlink is license for the current page. E.g. with the following hyperlink:
<a href="http://creativecommons.org/licenses/by/2.0/" rel="license">cc by 2.0</a>
the author indicates that the page is licensed under a Creative Commons 2.0 Attribution Required license.
Multiple such rel="license" hyperlinks indicate that the page is available under any of the referred licenses. E.g. the following hyperlinks could be used to declare that a page is available under either a Creative Commons 2.0 Attribution Required license or the Apache 2.0 license:
<a href="http://creativecommons.org/licenses/by/2.0/" rel="license">cc by 2.0</a> <a href="http://www.apache.org/licenses/LICENSE-2.0" rel="license">Apache 2.0</a>
