But we don't yet have interoperability in graph metadata/management.   
That's what IMHO we're trying to achieve here - the use cases I've tried 
to write up all seem to involve that. How can we reliably convey 
provenance metadata when there's no clarity about when/if different 
"graphs" will be changing?   Does metadata about one "graph" also apply 
to another "graph" that has the same triples?  (The answer depends on 
whether the metadata is really about a g-box or a g-snap -- I think 
people can get clarity on it when they consider whether the metadata 
would still hold if the "graph" changed.)
