Hello Mathieu! I agree that tracing the full history of a data cite is important, independent of license. I'm thinking about scalable solutions for this. It's definitely not the only factor in reliability; but it does matter who entered the data (for instance) as one way to estimate the importance of doublechecking a cited source to confirm that the data is found there.

I agree this is misconception that a copyright license make any direct change to data reliability. But attribution requirement does somewhat indirectly have an impact on it, as it... enforces traceability. That is I strongly disagree with the following assertion: "a license that requires BY sucks so hard for data [because] attribution requirements grow very quickly". To my mind it is equivalent to say that we will throw away traceability because it is subjectively judged too large a burden, without providing any start of evidence that it indeed can't be managed, at least with Wikimedia current ressources.
Now, I don't say traceability is the sole factor one should take into account in data reliability, but certainly it is one of them.
