RE: ISSUE-94 (n-ary constucts and RDF): Problem with roundtripping when going from functional-style syntax into RDF and back

Hello Peter,

I am not sure I understand what you mean with (1) and (2): how does round-tripping through OWL/RDF differ from roundtripping through
RDF graphs?

To make things clear, the type of roundtripping that this issue talks about is the following:

OWL Functional Syntax -> RDF graph (or OWL/RDF) -> OWL Functional Syntax

Regards,

	Boris
