We have so far regarded "Version" as a bad concept. There is no objective
way to define what differences different versions may have.
"Version" is a fuzzy notion
for one of two or more similar objects with a derivation history between them. It is
a relative concept, and as such does not qualify as class in an ontology, but as relationship:
"is version of".
The fact that there is a derivation processes linking two data sets should
be enough from a Provenance point of view. A "has derivative" link is a deduction
from the process. One might specify which sorts of processes would be regarded to
be allowed for derivations that lead to "versions". Only then we may have a reasonable definition
of "is version of". I regard it however as much too specific for a core Provenance model.
