As the 4.0 license allows for licensees to specify a custom copyright notice, which reusers must retain in any reproductions and redistributions, would the new cc:Notice tag actually contain this custom copyright notice, or is it for something else?

I for one would like to see the copyright notice be part of the license RDFa, since it’s unrealistic to expect reusers to retain information that can only be found by visually browsing the publisher’s site, and trying to locate such information (possibly in a foreign language, even).

Hi all,

Recently I’ve been working with Antoine Isaac (in cc) from Europeana on the machine readability of the deed pages of the 4.0 licenses. Antoine noticed that the RDF attached to the attribution license (and all other licenses) was not in sync with the separate RDF file.

Compare:

the RDFa of http://creativecommons.org/licenses/by/4.0/ (using http://www.w3.org/2012/pyRdfa/extract?uri=http%3A%2F%2Fcreativecommons.org%2Flicenses%2Fby%2F4.0%2F&format=turtle&rdfagraph=output&vocab_expansion=false&rdfa_lite=false&embedded_rdf=true&space_preserve=true&vocab_cache=true&vocab_cache_report=false&vocab_cache_refresh=false)
to

http://creativecommons.org/licenses/by/4.0/rdf 

The latter has a cc:requires cc:Notice which is missing in the former.

The consequence of this is that machine readers could get confused because there are contradicting sources. Also software based on this standard could produce wrong information.

To fix this problem we propose to move the the rdfa of cc:Attribution and add a cc:Notice RDFa tag. We’ve created a pull request that details this change here: https://github.com/creativecommons/creativecommons.org/pull/18

What do you guys think of this change request? Did we overlook something and is this the most elegant way to fix this problem?

Many thanks to Antoine for pointing this out and working on a fix with me.

Cheers,

Maarten
