I would happily add the DBpedia ontology to the Linked Open Vocabularies
data base, but I'm afraid to say that this version is still published in a
completely non LOV-able way.

- The ontology namespace http://dbpedia.org/ontology/ is dereferenceable,
but what it yields is neither the ontology content, nor even proper
metadata beyond owl:versionInfo 4.0-SNAPSHOT. Big deal :) To put it short,
the description you GET from this URI is basically useless.

- To get the ontology content, you have to make your way through the
documentation at http://wiki.dbpedia.org/Ontology2014, find out that the
ontology file is available at
http://downloads.dbpedia.org/2014/dbpedia_2014.owl.bz2 in the form of an
archive that you have to open to get the RDF content itself. Which does not
provide more metadata than the above, BTW. Nor link to the prior version,

I'm really sad to see DBpedia giving such a bad practice example for the
publication of its ontology. This point has already been made for previous
versions, I was hoping to find some improvement in this version.

I really think that it should be peanuts to fix this given the tremendous
task force and technical infrastructure supporting DBpedia. If there are
technical reasons preventing this ontology to be properly published at its
namespace, I'm curious to hear about them.

Best regards
