Manu's comment [1] spurred me to try show why we care about the
difference between a g-snap and a g-box.  

Intuitively, it matters to me because when I see

   <g> cc:license cc:by

I want to know what is being licensed, or when I see

   <g> dc:creator "John Smith"

I want to know what I'm being told he created.

Also, the different types have different ideas about identity; there is
only one g-snap containing any given set of triples, so that affects the
kind of metadata we can meaningfully apply to it.

To explore that a little more, I made a table of properties and
whether/how I thought they applied to the different types of things we
sometimes call an RDF "graph":

[1] "I really, really don't like all of the new terminology that the group
    is creating - having both 'graph' and 'layer' doesn't help simplify
    this stuff to Web developers. Use a base word, like 'graph' and
    modify it for the different types of graphs - graph snapshot,
    graph container, etc."
