I believe we are generally most keen on the named graph / separate RDF
resources per account (or per provenance container - however you want
to group these).

I believe linking accounts to everything would mean that we can't use
OWL/RDF properties directly, and would always have glue resources, for
instance for asserting conflicting views of attributes on an entity.
(At least not without using distinct identifiers for per entity per
account - which is different from the OPM-DM approach and adds a
question on how to link these two entities).

In OPMO this was easily solved because every edge is represented by a
glue class like WasControlledBy or Used - our current PROV-O approach
is to avoid these until we find evidence of the need for such.
