Current HTML documents designate a Creative Commons license through linking. RDF is included in an HTML comment. In most cases, the document being licensed is the current HTML page, and the expression of such a license is a single RDF triple:
"" <http://web.resource.org/cc/License> <http://creativecommons.org/licenses/by-sa-2.0/>

In some cases, individual elements within a page may be licensed under different Creative Commons licenses, or, more importantly, individually declared (e.g. a page with a series of images). In those cases, the RDF subjects should be designated as the individual images, PDF files, etc...
