This doesn't make sense.

If you are asserting that @itemid is used to refer to the same abstract thing,
then shouldn't properties associated with that abstract thing be reflected when
you retrieve that thing?

That is, if I add properties to "http://example.org/things#foo" in separate
parts of a document, when I retrieve an item identified as
"http://example.org/things#foo", then I would expect that all properties added
to that item would be returned to me.

Why is this not the case?
