Perhaps "durable" is strange name, as it sounds like it will last a
while, like a good pair of shoes.

What seems to come out of this organization is a hint that any
prov:InstantaneousEvent (DM term, so I guess OK for now) like End,
Start, Generation, can be linked with a prov:TimeInstant.

prov:Durable's like prov:Activity (and no other? prov:Entity
possibly?) could be linked with prov:TimeInterval - that is they have
a start and end. prov:occuredDuring does not quite reflect this - it
just says that the activity at least happened/lived during that
interval - but could have lasted longer.

prov:hadTemporalExtent is still in the ontology with an empty domain -
when to use hadTemporalExtent vs occuredAt?

prov:startedAt, prov:EndedAt are not related to the other time properties.

http://www.w3.org/2011/prov/wiki/ProvRDF  does not seem to reflect
these new properties/classes.
