That's probably worth filing in w3c/csvw for some hypothetical future group to take up, and to get more visibility from those who watch it.

So, to be clear, if you require `rdf/reasoner` and do `RDF::Reasoner.apply(:rdfs)` I can see that ```ruby RDF::Vocab::SKOS.prefLabel.entail(:subPropertyOf).map(&:pname) # => [ "rdfs:label", "skos:prefLabel" ] ``` But, ```ruby RDF::RDFS.label.entail(:subProperty).map(&:pname) # => [...

It should through a `::JSON::ParserError` if there's a problem parsing the metadata file, as that is native behavior of the JSON gem. You might try adding "--validate" and/or "--debug" to...

Well, the writer did get a lot of work to be able to write out full N3 Formulae, vs. just Turtle, but most of that shouldn't have come into play....

Note that `RDF::List(*(0...100)).dump(:ttl)` is fairly slow too, but not quite as slow as `:n3`.

I’m sure you’re right. Emphasis was on getting the functionality in rather than optimization. A PR would be welcome.
