There is no overlap, but there is a nice conceptual suggestion.  I suggested, based on reading the PROV-DM doc, that we should start thinking about ISSUE-33 in relation to non-hierarchical subgraphs.

Sorry for any confusion.

Perhaps their idea of the wasComplementOf relation makes more sense than our loaded and overly-hierarchical concept of a subgraph.  It seems to me that we could avoid a lot of trouble related to our ISSUE-33 if we could relate graphs to one another non-hierarchically:

Although a g-box is an entity in our minds, it matches their definition of an Activity, in that it is something that develops through time and is not necessarily identifiable by it's characteristics at any given point in time.  Perhaps we should challenge our own thinking in regard to a g-box being more of a process than an entity, which I think fits with Sandro's and Andy's recent messages.
