Mike, all,

thank you very much for this input. So do I understand it correctly that during development and testing, we can can go with CC-0, and later relicense to whatever seems suitable, which is possible with CC-0?

To go now with a license that will prevent us from migrating later, either CC-BY-SA 4.0 or ODbL, seems to be too early to decide now.

Cheers,
Denny

I don't think that's true. (Following probably of near zero interest
for wikidata, other than noting how annoying the topic is -- I almost
joked in previous email that if wonderful Microdata/Microformats/RDFa
discussion can be put off, hopefully joyous license discussion can
too. :-))

In the case of version 3.0 jurisdiction ports in the EU, database
rights are waived, but that's a long way from CC0 -- conditions of the
license are explicitly waived when use of the licensed work only
involves the exercise of database rights and not copyright -- given
the low bar to copyright, that's not often. CC0 unambiguously waives
copyright and related rights. Given a database under CC0, recipient
has no worries (assuming good provenance). Given a database under
CC-BY-SA-3.0-FR, recipient has to comply or figure out whether the
database is subject to copyright at all, which different lawyers will
likely give different answers to, meaning risk not obviated.

In the case of other versions, eg 3.0 unported, which Wikimedia
projects use, database rights aren't addressed at all, so the
situation is not CC0, but the reverse, default database rights. Which
sounds far worse, but then I know of no non-theoretical complaint in
which this has come up, and it is possible there's an implicit
license.

I should have linked to
http://wiki.creativecommons.org/Data#How_.28if_at_all.29_are_sui_generis_database_rights_addressed_in_CC_licenses.3F
which explains some of this in a few more words.

Much appreciated. :)
