Creative Commons provides information on licenses for three audiences: lawyers, humans and machines. The machine-readable information is described using RDF and made available from the Subversion repository in the license.rdf/license_rdf module.
Files in the
license_rdf module are named using the following convention:
More generally, you can take the URL of a license (i.e.
http://creativecommons.org/licenses/by/3.0/), strip the protocol information (
http://) and replace all forward-slashes (
/) with underscores (
_) to arrive at the base filename. Liblicense provides a function to perform this mapping for you.
Each file contains the RDF (encoded as RDF/XML) describing the particular license.
The license RDF files are used in the following CC applications:
- The license engine
- OpenOffice.org add-in
