[...] dbpedia can also be seen as a huge ontology that assigns URIs to plenty of concepts and backs these URIs with with dereferencable RDF descriptions.We have advanced a tech level!
This is really good timing, as I just recently considered using TDB URNs for referencing non-retrievable things and concepts (using TDB-versions of URLs to Wikipedia articles and web sites). Finding out if the idea of TDB and DURI URNs have been long since abandoned was my next step down that path. (Then there's the use of
owl:InverseFunctionalPropertyand bnodes (or "just-in-time"-invented ad-hoc URIs) and throwing in
owl:sameAsif official ones are discovered..)
With DBPedia, a lot of that becomes unnecessary. The availibility of public, durable URIs for common concepts will surely ease the integration of disparate sources of knowledge. That is, if we start to use dbpedia-URIs in our statements.
And gone will be the strangeness of saying "I'm interested in [the word 'semantics']", "This text was edited with [the website <http://vim.org>]" and "I was born in [the wikipedia article about 'Stockholm']"..
