I vote for option 2, definitely.
Statements (nor trees, nor HTML pages) are not resources :
reosurces are "conceptual mappings", which *denote* some (set of) entity.

The spec does not say that Statements are resources.
It just says that the "reified statement" (a resource) represents the original statement.
But as Graham pointed out, something can have more than one representation.

PS: I'm just thinking about some intersting interpretation :
since a resource can denote more than one entity,
isn't it fair to consider that "the reified statement" (the *resource* representing the original statement) denotes *both* the abstract statement and the stating.
Just a thought...

Sometimes I think the surest sign that intelligent life exists elsewhere in the
universe is that none of it has tried to contact us.
