I was very glad to do that (during the 42 hours it took me to come back
from Boston (after the all-group-meeting and technical-plenary) to my
home in Belgium (canceled flight, train instead of plane, etc ...))

That is indeed a good thing to be explicit about and the example
actually still works (with euler) and BTW that's what I find so
interesting in N3, when you mix in things or when you have things
in the form before term-rewriting (to come to Horn clauses or so),
they still give some evidence (something like Socratic completeness?-)

Well, they came from Mike Dean who wrote them up in RuleML
during the RDF-IG F2F meeting last february as an "early RuleML feedback".
The URI is http://www.daml.org/2001/01/gedcom/gedcom-relations.xml
So all credits should go to Mike :-(sorry that I forgot that ...)
