"Wherever two people describe the provenance of a same thing,

* we are nose diving back to owl:sameAs with this ^^

* The example is reasonable (date-specific URI versus non)


"To allow for identifiers to be chosen freely and independently by each  user, the PROV data model introduces relations
that allow entities  to be linked together.
The following two relations are introduced for expressing  specialized or alternate entities."

^^ this does not convey the "levels of detail" aspect well enough - it emphasizes too much on the "choose your own URI" wild west of the web.


References and Things should not be involved in defining specialization. We've just pushed the "Thing vs. Entity" argument into specialization.

"An entity is a specialization
 of another if they refer to some common thing but the former is a more
constrained entity than the latter. The common thing do not need to be
identified. "
