Updating data that was imported in 2018/ adding referencesGreetings, I hope this message finds you well. Being an intern at Kunstenpunt, an organization that imported its database in 2018, I am to update some of that data and add references to some of the properties that have been created in 2018. To do so, I need to make sure those properties were not edited by someone else to make sure of the integrity of the data that I want to make changes to. I have been trying to do this using schema: dateModified feature of sparql language in Wikidata query service. However, the data that I receive is in conflict with the items's Wikidata history page. Here is the query I have been trying out:

Use at

• https://query.wikidata.org/sparql

PREFIX wikibase: <http://wikiba.se/ontology#>
PREFIX wdt: <http://www.wikidata.org/prop/direct/>
PREFIX schema: <http://schema.org/>
PREFIX bd: <http://www.bigdata.com/rdf#>
SELECT ?itemLabel ?countryLabel ?change 
WHERE {
  ?item wdt:P5164 ?id ;
        wdt:P17 ?country.
  ?country schema:dateModified ?change .
  SERVICE wikibase:label { bd:serviceParam wikibase:language "[AUTO_LANGUAGE],nl,en". }             
}
