Dear prov-o team,

In my review, I focused on a subset usage, derivation, generation, and 
association

I raised a few issues:

- (ISSUE-253) http://www.w3.org/2011/prov/track/issues/253
   some properties (e.g. activity, entity, adoptedPlan) of involvements 
need to made functional

- (ISSUE-253) http://www.w3.org/2011/prov/track/issues/253
   the domain of hadTemporalExtent is broader than in prov-dm

- (ISSUE-262) http://www.w3.org/2011/prov/track/issues/262
   the ontology seems to allow an entity to be used (with qualified 
usage) by another entity.

- (ISSUE-263) http://www.w3.org/2011/prov/track/issues/263
    Involvements such as usage can be shared by multiple activities.

Furthermore, the ontology allows for instances of involvements to be 
expressed, without
specifying its subclass (Usage, Generation, etc). This is not aligned 
with the data model.

Choice of name: I understand 'hadTemporalExtent' as 'had a duration'. 
But Usage and Generation,
for instance, have got instantaneous time. I don't understand why 
xsd:dateTime is not directly associated
by means of a data property.

Regards,
Luc
