It makes more sense (to me at least) to fix the second part as naming 
the the graph value.

X names the graph (graph value).

owl:sameAs could be used in  "X --???-->  graph".

The common use case of using the grapgh container location as the 4th 
slot is "hasRepresentation" would be in the ":g ---> X" step.

:location :hasRepresentation value .

":g --denotes--> X" happens just by using :g.

I have an action to write some short use cases but these previosu 
messages do fit the model as I think of it:
