I share Denny's worries.
If we adopt ODBL, all WMF projects *will have to* add a note about
structured data taken from Wikidata (like "data are released in ODBL"
or similar), or they should be bi-licensed (CC-BY-SA 3.0 Unported +
ODBL what.ever).
If we keep licensing Wikidata with a CC0 (which is, in fact, a PD-like
license), that allows Wikipedia to re-use data with CC-BY-SA 3.0
Unported without any problem. Then, when CC-BY-SA 4.0 will be
released, we can migrate ALL projects to the new license.
I don't see any other possibilities - I do know something about
licensing and stuff, but I may be wrong.
Dual licensing under ODBL + CC-BY-SA?
Or even ODBL + CC-BY-SA + GFDL, to keep the legacy license as well.
You could also ODBL with an additional permission to relicense it under
CC-BY-SA or GFDL when aggregated with another work (slightly different
than a dual licensing, but pretty much the same).
