Reinhold,
This paper was a pleasure to read!
There were a few places where I couldn't reconcile what
was written with my intutions:
o (2) statement(s,p,o) => uri(s) ...
I'm not sure how to interpret uri(s). RDF has anonymous
resources. Is uri(s) true for such resources? Is it
true for a reified statement?
o (5) lit(o) => instanceOf(o, rdfs_Literal)
I was curious why there is no equivalent
res(o) => instanceOf(o, rdfs_Resource)
o In the discussion at the end of 3.2.4 you express some
concerns about the definition of subPropertyOf. RDF
permits a resource to have the same property with more
than one value, i.e.
statement(S, P, O1) and statement(S, P, O2)
is just fine. There is therefore no requirement that
Vsp has only one value.
