Scope is as qualifier (Q54828449): the property must be used by specified way only (Help)

List of violations of this constraint: Database reports/Constraint violations/P2312#Scope, hourly updated report, SPARQL

Type “Wikidata property for quantities (Q52513243)”: item must contain property “instance of (P31)” with classes “Wikidata property for quantities (Q52513243)” or their subclasses (defined using subclass of (P279)). (Help)

Exceptions are possible as rare values may exist. Exceptions can be specified using exception to constraint (P2303).

Allowed entity types are Wikibase item (Q29934200), Wikibase property (Q29934218): the property may only be used on a certain entity type (Help)

Exceptions are possible as rare values may exist. Exceptions can be specified using exception to constraint (P2303).

Minimum quantity value of a "range constraint" or "difference-within-range constraint" must be less than the maximum quantity value of the range
For a range constraint (Q21510860) or difference-within-range constraint (Q21510854), the value of the minimum value (P2313) qualifier must be less than the value of the maximum value (P2312) qualifier. (Help)

Minimum date value of a "range constraint" must be less than the maximum date value of the range
For a range constraint (Q21510860), the value of the minimum date (property constraint) (P2310) qualifier must be less than the value of the maximum date (property constraint) (P2311) qualifier. (Help)
