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.

    <cc:license rdf:resource="http://www.creativecommons.org/licenses/example2" />
  </item> 
</rdf:RDF>

Additional Metadata

Note that this is a draft we are currently working on; this notice will be removed after collecting feedback.

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 Podcasts

Using RDFa you can also provide additional metadata about linked content. This is useful when deploying a podcast; your XHTML can provide rich metadata which allows clients to increase confidence in the metadata.
