No you cannot: CC-BY-SA is not intended for data, so regarding data
you should never use any CC licence (pre-version 4.0, v4 will address
database rights) other than CC0. That's why if you want BY-SA
conditions, the good choice is ODbL which was created by the Open
Knowledge Foundation exactly for this, a share alike licence for
Like I already said a few months back, I totally agree with Alex :
using ODbL and therefore keep along the BY-SA choice that rules
Wikipedia is the most logical choice. Mocing towards CC0 would be a
source of a lot of possible conflicts and possible infringements of
Wikipedia's content licence.

Can you give me a reference for the statement that
CCBYSA and ODBL are
compatible? I understand that they have certain similarities, but I want to
understand if I can take ODBL content and relicense it under CCBYSA and the
other way around.
Or else what do you mean with "compatible"?

I guess things would be far more easier if WikiData would choose a
CCBYSA-compatible database license like ODbL. I can only repeat myself, that
the OpenStreetMap community went through a similar discussion and decided to
respect database rights and keep their data as clean as possible. Because
they didn't want to take the legal risk, that after 5 years a big company
like Google will sue them and so OSM might loose the work of 5 years.
I also think that there are two aspects in this topic: 1) the pure legal
aspects and 2) how we (Wikipedia users) treat each other and respect the
work of others. So the WMF might say: hey you European guys with your DB
rights... bad luck that you invest all your work into a US hosted project -
we don't care about your rights. Even _if_ this is legally not to be
objected, is it fair against the users?
To make it clear: I'm into lots of list articles (streets and monuments)
which contains lots of data. This content is licenced under CCBYSA today.
The day when all this content will be expropriated by WikiData, is the day
I'll stop my work for these Wikipedia projects.
