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).
