A property is considered "undefined" if it does not appear as subject of
any triple (e.g. ex:myProperty rdf:type rdf:Property would resolve that)
and does not appear in a SHACL property shape (?ps sh:path ex:myProperty).
In this particular case, include the SHACL version of schema.org to
resolve the references of familyName and deathDate.

I understand the first and the last 2 errors but not sure what exactly
"Use of undefined property" means. Where should I define those properties?
I also looked at the validation SPARQL in
"teamworkconstraints:UndefinedPredicateConstraint" but don't quite
understand it.

SELECT $this ?path ?value
WHERE {
$this ?path ?value .
FILTER (?path NOT IN (<http://topbraid.org/search#defaultSearch>)) .
FILTER NOT EXISTS { ?path ?p ?o }
FILTER NOT EXISTS { ?ps sh:path ?path }
}

Thanks!
