Ask HN: Why are URNs not more popular?

URN are the "missing link" in the semantic web. If you look at examples where somebody writes an RDF file they typically use identifiers like

   <http://dbpedia.org/resource/Tin>

which are fine for cases where you want to publish the data on the web but not for the much more common case of "our own private data".

It is straightforward in principle to use URNs, but it is not easy to find examples or discussion of best practices with URNs. For one thing you can always write

   <urn:uuid:6e8bc430-9c3a-11d9-9669-0800200c9a66>

so you can generate as many unique ids as you need.

You can always use something like <#abc> or :abc for terms of the document being described or just an extra graph that is just private and not shared like <http://comp.com/abc>. Anyhow I don't think this is what is missing to make the semantic web work.

I remember the semantic web people telling me when asking about URN they said "we don't use those anymore", so that is that, and the story of the semantic web.
