So the prov:Collection would just be an anchor point with no
relations, except prov:Dictionary is a subclass?

I would think memberOf() would be a minimum requirement for a
prov:Collection to be useful - but that would raise question on how it
relates to Dictionary memberOf().

The simplest solution is that the simple memberOf() just says that an
entity was a member of the collection - but nothing about how it got
there (it is not a provenance relation, it is more of an attribute of
the entity).

Then both dictionary insertion and dictionary membership will imply
the simple entity membership. (and dictionary removal could infer
membership in the old collection - but I know that is a  bomb we don't
want to defuse)
