Yes, test cases should help define those views. One possible outcome is 
an explicit split between those semantics, and that doesn't have to be a 
bad thing.

I, for one, keep being unimpressed by the Turtle syntax, which ends up 
becoming quite redundant because depending on the interpretation a 
triple needs to be stated twice (once for the actual assertion and once 
for the reifications). We are for now using a syntax such as

ex:subject ex:predicate ex:object [[
     ex:created "2010-10-10"^^xsd:date ;

to state both at the same time, and this seems to work better. But in 
the absence of any formal starting point (such as a respec spec and a 
proper development process with regular meetings and bug tracker 
tickets) I guess many implementations will just go with the original 
syntax or diverge further. Maybe everyone here is waiting for Olaf to 
take more control again, but that's not really his job or responsibility 
and maybe it's time for the implementers to chose a chair, have a couple 
of meetings and establish productive processes?
