I found that statement of yours a bit ambiguous and hope you don't mind
me trying to clarify:
It depends on /where/ we see this...
In the file you mentioned there is /one/ anonymous chicken pickin weasel
temporarily referred to as (named) _:x
Any repetition of the statement and any other statement using _:x in
subject or object position would refer to the very same weasel, *as
long as stated in the same file*.
(It's exactly as in your usage of "the following file": You don't
give it a name and if you use the same words in another mail I
couldn't know whether it is the one from this mail or a completely
> A different file could use _:x to refer to some Chicken.
There the differences start as we can never tell whether _:x in
the different file is the same one or a different one anonymous
In practice this matters when one wants to add or remove individual
statements or subgraphs from graphs: When the graphs or subgraphs
have blank nodes as their origin, you usually can't.
