I fully agree. If CC4 comes before any decision is to be made with WikiData's licence it would only be natural to use CC-BY-SA for data as well as for content. My pleading for ODbL is as a temporary fix since right now, in countries such as France, releasing data under CC-anything basically means CC0 on the data without producers using it even knowing it (latest one yesterday here data.visitprovence.com )
I was only arguing in favor to pursue the common goods attitude behind the copyleft choice that was made before for Wikipedia.

A few quick points:
- The main lack of suitability of CC licenses for databases is that
they don't explicitly (with a few exceptions in the case of certain jurisdiction "ports" which we can ignore) grant permissions that mitigate non-copyright database rights. If not for this, ODbL and some government-specific licenses such as UK OGL would probably not have been motivated enough to exist
- However, the bar for plain old copyright restricting databases is
unfortunately low, especially outside the US, which may in part explain use of various CC licenses for various databases from the very beginning of CC; some background at http://creativecommons.org/weblog/entry/26283
- Version 4.0 of the various CC licenses will almost certainly license
sui generis database rights and similar just as they do copyright. I would hope that Wikimedia projects (in general, ignoring Wikidata for now) will move to 4.0 shortly after it is done, otherwise it won't be actually done IMO. :) 1st draft announced today http://creativecommons.org/weblog/entry/32157
- Although it may not have happened if CC 3.0 or before licenses
explicitly addressed database rights, ODbL is similar to CC-BY-SA in that they're both copyleft/reciprocal/viral/hereditary licenses, they are quite different in detail, most significantly:
- ODbL requires machine-readable source (entire derivative database,
or patch); CC-BY-SA has no source requirement
- ODbL allows for "produced works" (eg a rendered map) not subject
to same license requirement; if work derivative of CC-BY-SA, same license must be used (modulo exceptions & limitations of course)
- The most significant issue is not a difference exactly: ODbL and
CC-BY-SA are each only compatible with themselves (and note that CC0 is donor compatible with them both, but obviously not recipient compatible)
- I would guess the first thing to figure out is whether compatibility
is needed, and where. At one extreme, Wikidata would have no choice but to use CC-BY-SA as that's what other Wikimedia projects are using, and it will be ingesting data from. At the other extreme, that data is all public domain and or there's community agreement on boundary of data and everything else, and Wikidata data can be CC0, ODbL, or whatever else is deemed to be the best fit.
IANAL etc, Mike

To keep along the sharing path that was adopted with the original choice
of
CC-BY-SA for contents one could argue in favor of OpenDataCommons' ODbL.
It
is basically the equivalent of CC-BY-SA but for data, and is the choice OpenStreetMap made among others. This could be a good way to ensure WikiData's full database won't be pivatised without any giving back to the community

Yep, until now we always have been discussing and are strongly leaning towards CC-0 for the data content, and CC-BY-SA for the textual content
of
Wikidata, i.e. the project pages, discussion pages, etc.
We are fully aware that most CC licenses are not adequate for data.

Hoi, The question if CC is the right license for data is a bit limited; what CC license?. There are many licenses available by Creative Commons.
When you consider facts, on their own they cannot be copyrighted and consequently licensed. A CC-0 license would work really well for them. Thanks, Gerard
