Re: actions related to collections

I've had similar concerns that the definitions for collections are "too heavyweight" to manage the membership of sets.

But while ignoring is name and looking at the modeling construct it provides, it's clear that this construct will be very useful in many real provenance problems (for example, the very ubiquitous need for provenance of function calls with their argument names and bindings).

Perhaps we can avoid the "too heavyweight for set membership" concerns raised by Satya and Jun by renaming what we have (prov:Collection) to something more appropriate, like prov:Dictionary?
