Pierre-Antoine's proposal uses a reified statement to
represent both a statement and a stating.  My concern
is that this can lead to contradictions.

Consider a statement S which occurs in two documents,
http://foo and http://bar.

Let RS be a reified statement representing both S and
its occurrence in http://foo.  Thus:

   (occursIn, RS, http://foo)

is true.  Is

   (occursIn, RS, http://bar)

true?  It is true of RS, the representation of S.
It is not true of RS the representation of the
stating of S in http://foo.

Is this a contradiction?

I really don't understand why folks are so reluctant
to accept that statements and their occurrences are
two different concepts and need different resources
to model them.  What is the big deal?

Brian
