It's a keen idea, but compiling that kind of extensive database is kind of impossible without some kind of major investment.

To wit...
A lot of that type of information IS already available on dozens of sites across the web (including this one) albeit in a fragmented way, and some of it is in foreign languages (which is fine for those of us who can read them, but obviously not so much for those who can't).

Still, to have it all under one roof would take an operation as dedicated as Wikipedia, and would probably need to be updated every six months or so- not to mention the whole process of vetting the information for empirical accuracy, in addition to occasional translation & legal accountability (which in turn implies the existence of a legal team).

so... $$$.

That's all very expensive & time-consuming, even for a volunteer effort (and how many years would it take before it's useable?). I mean, look at Wikipedia or Linux; public broadcasting, at all the fund drives & donation requests; bandwidth & printing aren't free, after all.
