This plugins adds the Creative Commons license of choice to a website's metadata.
The plugin provides no UI for configuring it. Instead, you must define a PHP
constant named CC_LICENSE
. This is most easily done by adding a snippet like
the following to your wp-config.php file:
define('CC_LICENSE', 'http://creativecommons.org/licenses/by-nc-sa/3.0/');
What exactly does this plugin add to my site?
It adds a <link rel="license" />
element to each page of your site. It also
adds an appropriate element to the XML feeds (rdf, rss, atom) for your site.
Can I override the license for a specific post?
Yes, a filter named cc_license
is called before returning the license. You
can override that value under whatever circumstances you want.
