View source for Site CC Portal and Metrics

If you run a [[Content Directory]] of some form, in addition to enabling (or in some cases mandating) CC licenses for works hosted, cataloged or otherwise curated, it is beneficial to provide users means to navigate and search CC-licensed material and accurate counts of licensed materials.

==Example: Flickr==

http://flickr.com/creativecommons provides all three:
* navigation for each license
* search for each license
* current number of photos under each license
* ([http://www.flickr.com/search/advanced/ Flickr advanced search] also enables search across licenses, supports [[CC Search Integration|URLs enabling inclusion in search.creativecommons.org]], and supports query by license in its API.)

One could do far worse than copying this interface.
