As the format is so regular, I don't think it is much to worry about 
because you could use perl to generate the information about each test 
without needing to understand the RDF that the Turtle serializes.

Thanks for doing this.


The files are empty - zero bytes
hg sync issue?

These tests


have relative URIs.  Could we make them absolute?

It does not affect the intent of the test and many N-Triples parsers 
aren't going to do IRI resolution for location base.

Spec comment - I think the spec should say that in the syntax, unlike 
Turtle, all IRIREFs MUST be absolute, i.e. no resolution required even 
against the location base.
