Re: resolving IDs

hi jim and tim,

thanks for considering this: Tracker, this is PROV-ISSUE-482

for now i'm simply assigning uuid1() hex strings as ids. these are
guaranteed to be unique. we will still have to think about those situations
where we need to reconcile these from different bundles to be the same
(e.g. the same agent - person, software, organization - did something).
however, this will also require standardization of certain entities and
organizations being registered at a uri.

cheers,

satra
