(I assume you appreciate I was speaking hypothetically.)

I used the term 'page at' here as a shorthand for 'document for which one 
obtains a representation by dereferencing the URI'.

Roy's comments point to a flaw in this...

Maybe colour wasn't such a good example, but I think could adapt the 
idea.  Suppose I designed and built the car.  Then I authored a document 
describing the car, and posted that document on the web.  So we might have:

   <http://example.org/myCar> ex:madeBy ex:Me .

I think that this assertion could reasonably be an enduring truth, whether 
<http://example.org/myCar> identifies the document or the car it describes.
