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 creativecommons/cc.licenserdf git repository.
Files in the
license_rdf module are named using the following convention:
More generally, you can take the URL of a license (i.e.
https://creativecommons.org/licenses/by/3.0/), strip the protocol information (
https://) 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. Information described by the RDF includes:
- license name, including translations
- license description, including translations
- license properties, as described by ccREL
The license RDF files are used in the following CC applications:
- The license engine
- OpenOfficeOrg Addin
- IIIF (International Image Interoperability Framework)
