The Digital Public Library of America‘s policy on metadata was discussed during the recent board of directors call, and the DPLA is, in my opinion, getting it exactly and admirably right. (See Infodocket for links.) The metadata that the DPLA aggregates will be openly available and in the public domain. But just so there won’t be any doubt or confusion, the policy begins by saying that it does not believe that most metadata is subject to copyright in the first place. Then, to make sure, it adds:
To the extent that the DPLA’s own contributions to selecting and arranging such metadata may be protected by copyright, the DPLA dedicates such contributions to the public domain pursuant to a CC0 license.
And then, clearly and plainly:
Given the purposes of the policy and the copyright status of the metadata, and pursuant to the DPLA’s terms of service, the DPLA ‘s users are free to harvest, collect, modify, and/or otherwise use any metadata contained in the DPLA.
