Hm. You may found the elephant:-)

Yes, in this case one would indeed get the example.org URI.

The question is: is this use case so strong as to nullify the advantages
of using CURIE-s in @about? Indeed, wikipedia uses such URI-s with ':'
quite a lot but the user can of course put full URI-s into the value of
@about...

Thanks!

Ivan
