Jon Udell says "lets give every fact its own home page on the web.
Absolutely. Numeric quantities, in particular, need this. The web needs to get a lot better at slinging numbers - not pages - and update events around the place.
Its starting to happen. Mostly, I think because of the emerging "web of things". Things like cosm and things like Personal Event Networks need "facts" to work with and a goodly number of said facts are numeric quantities.
Now it can coherently be argued that RDF makes numerical facts just drop out of its grander epistemological theory but I worry that RDF is seen as overkill for situations where it really is just a number you are looking for.
If the URI is http://facts.com/populations/ireland. All I want to do is to a HTTP GET and get back 4487000.
The simple case should be simple.
