In a nutshell, you can safely assume that only the property 'stated in'
matters.
I think 'inferred from' (P3452) should also be considered as an internal
reference.
Probably but this property is not often used.
I managed to make a query work: https://w.wiki/FqH (number of use of the 76
properties used in the references space for items located in Paris, the
last part is to have a small sample and avoid timeout ; also, maybe the
SPARQL code could be optimized, I just wanted to have an overview and
confirm my assumption that only a few property are widely used)
Here's a version of the query with labels for the properties, making its
output a bit more readable:
https://w.wiki/Fr9
Note that for external references, it's very common just to give the
identifier in the external database, via the appropriate property
(perhaps accompanied by a "retrieved" = <date>, but usually not.
