I agree that “named entity” makes more sense. I’ll pass that edit suggestion 
along to the folks who maintain the page.

Here is a blog post from 2011 where we talk about remodeling VIAF into a 
coherent hub-and-spoke model revolving around the entity itself.

Well, http://www.oclc.org/en/viaf.html says that VIAF

  *   Links national and regional-level authority records, creating a cluster 
record for each unique name
(my bolding). Some clarification is needed, if the "name" is supposed to be 
"named entity" instead.

VIAF identifies a variety of things, including people, pseudonyms, 
organizations, places, etc. There is no intentional distinction between those 
things and their “identity”.

That's because P214 should be a property of an identity, not of a person. We 
conflate the two concepts at our peril. One person can have multiple 
identities, aliases, pseudonyms, characters, roles, jobs, etc. Sometimes the 
same identity is adopted by multiple people, either sequentially or 
simultaneously: "I am Spartacus!", "John Bull", "G.I. Joe", "POTUS", "The King 
is dead, long live the King!", "Editor in Chief of the New York Times", ...

2. Single value violations

https://www.wikidata.org/wiki/Wikidata:Database_reports/Constraint_violations/P214#<https://www.wikidata.org/wiki/Wikidata:Database_reports/Constraint_violations/P214>"Single_value"_violations

I don't understand this at all. Apologies, I feel very dumb but would 
appreciate maybe a general, non-tech speak explanation if someone might be so 
kind.


It's explained here:
https://www.wikidata.org/wiki/Q19474404

It means that the "VIAF Identifier" P214 property can only have 1 value.  But 
you can treat this as a warning really because you will be loading multiple 
VIAF identifiers for the same person...and getting VIAF to merge or cleanup 
later...which hopefully bots will then pickup and handle the extra identifiers 
being deleted..
