When using QuickStatements, I mistakenly added "based on heuristic" as a property of the qualifiers of Wikidata statements instead of using it as a property for the references of Wikidata statements. The batch worked and added "based on heuristic" information as qualifiers to Wikidata statements instead of adding them as references to Wikidata statements. However, it is clearly mentioned in the Wikidata property constraints of "based on heuristic" that the property can only be used in references of Wikidata statements. I ask if QuickStatements can be further developed to adjust QuickStatements batches using Wikidata Property Constraints.
