Help:Property constraints portal/Property Scope Constraint
This is the documentation page for a particular constraint type. See Help:Property constraints portal for a general overview of property constraints. |
property scope constraint (Q53869507) specifies how to use the property: for the main value of a statement, in a reference or as qualifier. You can specify single usage, for example for the main value of a statement only. Or multiple usage, for example: for the main value and in reference section.
This constraint applies to most properties, e. g. head of government (P6), father (P22), mother (P25), Freebase ID (P646), etc.
