Fixing errors
A common error made on Wikidata is to give part of a World Heritage site the property heritage status: World Heritage site, which is incorrect. Correctly labeled sites will include the property World Heritage criteria (2005). These incorrectly labeled sites can be corrected by removing the property heritage status and adding the property part of and the World Heritage site which it is a part of.
These incorrectly labelled sites can most easily be found by looking at the list above and finding any sites with a small number of articles across different languages.
