Re: DBpedia 3.2 release, including DBpedia Ontology and RDF links to Freebase

''Most people don't care about structure, they care about content.''

I am sorry... but that's just nonsense. There is no content (elements) 
without structure (context, elements' relationships, consolidative meaning), 
as there is no structure without content.  If your application without 
structure (unifying context), it is just an alphabet soup of data.

Most people don't care about structure, they care about content.

DBpedia makes Wikipedia's implicit structure explicit in order to make
its content more accessible and (re)usable.

That's it.
