Now this is interesting (from the page):

"Wikidata is a secondary database. Wikidata will not simply record statements, but it will also record their sources, thus also allowing to reflect the diversity of knowledge available in reality."

That sounds pretty cool to me, because you could potentially upload probabalistic data from statistical analysis. If they make this so that you can tell how reliable the source is, you could upload information that's accurate to a given degree of probability.

It would be very interesting if you could version data by reliability, so that less-reliable data could eventually be replaced by definitive data. This is an achilles heel of current data modeling systems.
