RSS 1.0 is a syndication (feed) format. The specification was published December 6, 2000. A module specification has been published for inclusion of licensing information in the feed.
Specifying a License
RSS 1.0 is encoded as RDF/XML. A license may applied to a channel, entry or image by adding an appropriate triple. The predicate should be http://creativecommons.org/ns#license. Older deployments may exist which use http://web.resource.org/cc/ as the root of the Creative Commons namespace.
The following example shows licensing at both the channel and entry levels.

Additional Metadata
A web statement provides additional confidence regarding metadata assertions. morePermissions allows content creators to provide a link to a URL where additional permissions, beyond those provided by the license, may be secured.
RSS 1.0 is RDF+XML, which allows additional metadata to be specified for individual objects.
The following example demonstrates providing a verification URL (web statement) as well as a URL where users may find information regarding additional permissions.
<item rdf:about="http://c.moreover.com/click/here.pl?r123">
<title>XML: A Disruptive Technology</title>
<link>http://c.moreover.com/click/here.pl?r123</link>
<cc:license rdf:resource="http://www.creativecommons.org/licenses/example2" />
<cc:morePermissions rdf:resource="http://example.org/pay_me" />
<xapRights:WebStatement rdf:resource="http://example.org/more_info" />
</item>
Note that this example uses an additional namespace, xapRights, which is defined as http://ns.adobe.com/xap/1.0/rights/.
Use with Enclosures
Enclosures (multimedia attachments to a feed) are specified for RSS 1.0 by mod_enclosure. License, verification (web statement) and more permissions metadata can be provided as with entries.
The following example demonstrates including an MP3 as an enclosure, with additional metadata about the MP3 provided.
