I understand you Jonathan, we did it like that
before, and we did similar ambiguous stuff
before in our entailment test case description.
I just wanted to say that we took that part of the
ambiguity out and I also understand that those
other constructs are not a standard yet.

When I read the OWL Semantics concerning rdf:type, I see nothing that has
to
do with any of

doc:Work
log:semantics

nor is there any requirement that the URI be of rdf:type owl:Ontology.

I understand the above are N3 constructs, but I don't think this issue has
anything to do with owl:imports as specified by the OWL Semantics. The fact
that you removed your implementation of owl:imports was given as evidence
that there is some problem with owl:imports. I don't see the problem with
owl:imports itself -- i.e. when you are *implementing it* just dereference
the URI and load the triples you get into the KB.
