attaching multiple licenses

Dear LODers,

I'm looking for a best practice for publishing multiple licenses along with
one rdf document.

Say I publish one URI for an artist:
http://example.org/resource/Madonna

I aggregate information from multiple sources about that artist, and those
sources have different licenses. One triple comes from a source under GNU
FDL, another triple from a source under Public Domain, and a owl:sameas link
which I want to publish under Creative Commons License. 

Any pointers to how to do that?

Thanks,
Georgi
