Specifically on the is..of rather than allowing reverse properties:

I don't like the use of "..is .. of .." -- this pseudo-English is, well, 
English-centric.

If a constrained (natural) language approach is desired, then adding 
features one by one seems to miss the opportunity for a systematic 
approach.  So why not a develop comprehensive solution

1/ Layer on top of Turtle or N-triples for now
    They are moving to different goals and timescales

2/ Have a comprehensive, prototyped and used system
    (that's more than is in N3 where it is just @has,
    @is ..  @of).

3/ Persuade people it's a "good thing"

4/ Submit to W3C with deployment experience.
