Is RDFn the same as RDF-star? Well, in the sense that each can encode the
other, yes. But this isn't a very useful sense of sameness.
More interesting is whether there is a natural correspondence between all of
RDFn and all of RDF-star. But there isn't, at least so far as I can ascertain
from the information given to the working group. RDF-star has unasserted
triples, which RDFn appears to lack. RDFn uses graphs with multi-edges, which
RDF-star does not provide.
