SPARQL UPDATE queries add standard vocabulary properties alongside existing custom predicates: schema:Person/Place/Organization types, schema:givenName/familyName/birthDate, owl:sameAs for authority links, wgs84:lat/long for coordinates, skos:Concept/prefLabel for enumerations, and rdfs:label for persons.
