Re: prov:Dictionary example - without the specs

Dictionary keys can be compared. Hence, after insertion and removal, we can always determine a new dictionary state if we knew the state before operation.

The key reason why we went for a dictionary and, say, a set of entities,
is that we are unable to decide whether an entity belongs to a set on the basis of
its urls (since the same entity may be denoted by multiple urls).


huh? Why does that matter? In that case, we wouldn't be able to do it for Dictionaries, either.

prov-wg,

I tried my hand at modeling the provenance of the U.S. Supreme Court's current membership, and its derivation to it's first membership.

The wiki page for the example is at:

http://www.w3.org/2011/prov/wiki/Eg-34-us-supreme-court-membership

In an attempt to take a fresh look at how we're modeling dictionaries (and collections?), I didn't reference PROV-DM, PROV-O, or any other examples or documentation -- I just tried to describe the subject matter.


How does it look?

I'd like to move PROV-O (and DM, if it needs tweaking) towards this kind of modeling and naming.

Discussion and feedback encouraged.

Later today, I'll try to start from scratch on the DM and work through the current PROV-O modeling, and then the recent threads on this topic.
I hope by then we can converge on a satisfactory design.

Regards,
Tim
