Description

This document aims to provide a format for metadata regarding the copyright license under which a SMIL document is released. As the name suggests, it originates from the Creative Commons project, but is not restricted to the licenses that they produce. Rather, it is designed to allow for the inclusion of any existing and future licenses, and to provide for the simple description thereof. More details on this can be found on the Creative Commons site, especially the metadata specification page.

General principles

Apply SMIL 2.0 metadata format to SMIL 1.0. Don't use 1.0 style metadata, because it's unlikely that there are readers that use it, and because 2.0 style metadata is more compatible with existing Creative Commons RDF recommendations.
Don't insert Creative Commons metadata into the rdf:description metadata format given as an example in the SMIL 2.0 metadata recommendation, since it is only an example and is somewhat hard to work with. In a document structured like the example in the SMIL 2.0 metadata recommendation, insert Creative Commons metadata as a cc:Work element which is a peer of rdf:description.

Examples

Simplified example:

<metadata id="meta-rdf">
   <rdf:RDF>
      <!-- Element containing license metadata here -->
   </rdf:RDF>
</metadata>

Detailed example:

<smil>
  <head>
    <metadata id="meta-rdf">
      <rdf:RDF

	 xmlns:dc = "http://purl.org/dc/elements/1.1/">
