Draft Specification 2005-02-06



For the moment this specification is (C)2004-2005 by the author(s) and Technorati. However, Technorati intends to submit this specification to a standards body with a liberal copyright/licensing policy such as the [WWW]GMPG. See the [WWW]GMPG Principles for more details. Anyone wishing to contribute to this effort MUST read those principles, especially those regarding copyright and licensing, and agree to them before contributing.


Technorati neither holds nor intends to apply for any patents on anything required to implement this specification.


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 Licenses

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>
