Exceptions are possible as rare values may exist. Exceptions can be specified using exception to constraint (P2303). List of violations of this constraint: Database reports/Constraint violations/P7825#Type Q47574, Q173227, Q15132612, SPARQL
Single value: this property generally contains a single value. (Help)
Exceptions are possible as rare values may exist. Exceptions can be specified using exception to constraint (P2303). List of violations of this constraint: Database reports/Constraint violations/P7825#Single value, SPARQL
Distinct values: this property likely contains a value that is different from all other items. (Help)
Exceptions are possible as rare values may exist. Exceptions can be specified using exception to constraint (P2303). List of violations of this constraint: Database reports/Constraint violations/P7825#Unique value, SPARQL (every item), SPARQL (by value)
Scope is as main value (Q54828448): the property must be used by specified way only (Help)
