Hi Olaf,

I'm confused. I read in the documents explaining RDF* that there is now a new
kind of object, a Triple, in addition to the ones that we already know about,
IRIs, Literals and Blank Nodes. It explains that a Triple lives in the set

    (IRI ⋃ BN ⋃ T) x IRI x (IRI ⋃ BN ⋃ L ⋃ T)

defined in a suitable recursive way. I understand that, and it makes sense.

Your message confuses me because it's unclear in what sense one triple is
equivalent to a set of five triples. Maybe I'm just dense. Is a triple in RDF* a
new kind of object or is it just an extension of the Turtle language to make it
more convenient to write down reification?
