This looks pretty good, Mark!

Might need to explode the definition of "provenance" in this context --- here
you imply *some* definition of whereItCameFrom and whoAuthoredIt, but there
might in fact be domain-specific definitions of "provenance objects" (i.e.
aggregations of provenance-informing properties that are useful to a
*particular* community).
