The http://world.silkapp.com site was actually built that way. It's a combination of information on Wikipedia & the CIA world factbook. We built a MediaWiki importer for this, that will be publicly available at some point. Also, some of the functionality may make it to the core product, but we'll have to see how this develops over time.

Silk does use pattern recognition to automatically infer data types already, so you won't have to specify that something is a location, date, currency, number, etc. The editor will find out itself. We are working hard to bring this kind of 'cleverness' to more and more aspects of the editor.
