Which is why I find aversion to EAV or EAV/CR when introducing RDF 
utterly bizarre.

RDF didn't invent the Graph Model. It simply added URIs as an evolution 
of an established model.

RDF will remain in a comprehension tizzy for as long as people attempt 
to introduce it to newcomers without historic perspective.

History helps anyone grok new subject matter.
