Help:Property constraints portal/Allowed entity types

allowed-entity-types constraint (Q52004125) specifies that a property may only be used on a certain entity type.

For example, Wikidata property example (P1855) should only be used on properties—not on items—so P1855 has the following statement:

property constraint (P2302)	allowed-entity-types constraint (Q52004125) edit item of property constraint (P2305) Wikibase property (Q29934218) 0 references add reference
		add value

The qualifier constraint scope (P4680) can be used to restrict the constraint to only apply when a property is used as a main value, as a qualifier, or as a references.

If no constraint scope (P4680) is specified, this constraint is checked everywhere.

Possible actions

There are several possible ways to address a violation of this constraint:

• It’s possible that the property is not the correct one to use for the statement, and a similar but different property should be used instead.
• It’s possible that the statement should not exist at all, and should be removed.
• It’s possible that the statement is a rare, but legitimate exception to the constraint, and nothing should be done.

Parameters

This constraint has one mandatory parameter:

item of property constraint (P2305)

Contains the allowed entity type(s), a subset of Wikibase item (Q29934200), Wikibase property (Q29934218), Wikibase lexeme (Q51885771), Wikibase form (Q54285143), Wikibase sense (Q54285715), Wikibase MediaInfo (Q59712033).
