Removes copyright meta tag, adds rel="license" to 'copyright' footer link

Attached:

Meta copyright tag contains a link to copyright info, which is quite relevant. Lacking a description of any particular motivation to move from the existing link to something else, resolving as INVALID for now. Keep in mind that microformat fads change quickly, and the link rel that was cool in 2006 might be ignored now. :)

Do you have a current reference for CC & copyright metadata best practices and actual known current usage by search engines?

(look for 'license' threads)

*rel="license" aply to the main content.
*No clear how search engines use it
*For instance, Google uses a regex to handle RDF.
*Wikipedia appears on their dicussion

The rel="license" link rel works now and works quickly. See this search, which is on a domain on which it was only recently added (in time with the CC-BY-SA switchover):
http://www.google.com/search?q=site%3Awikifur.com&as_rights=(cc_publicdomain|cc_attribute|cc_sharealike).-(cc_noncommercial|cc_nonderived)

It is used by the Creative Commons link generator:
http://creativecommons.org/license/ (try generating a license, you'll see it there)

I personally feel that Project:Copyrights is a more appropriate location for the meta copyright tag to point to, if it exists. The W3C specifies it as "a copyright statement for the current document." (http://www.w3.org/TR/html4/types.html#h-6.12)
