<- What do you mean "without using any inference". Maybe we differ in our
<- definitions, but I consider the above to be inference rules.

Yep, probably definitions.
If I was to say "2 + 2" I wouldn't be performing any addition, and wouldn't
expect you to see "4".
No inference has been carried out on "if (X, rdfs:class, Female) then (X,
address, "Ms")", though presumably your average inference engine in the
street would know what to do.
