Help:Property constraints portal/Entity suggestions from constraint definitions

When adding a main value for a property with the data type item (e.g. property constraint (P2302)), the constraint definition of that property is evaluated. If a one-of constraint is present, items defined in that constraint are suggested by the entity selector. When the user starts typing only items are shown that are matching the search term. Items present in the constraint definition will be shown at the top of the entity selector.

When adding a qualifier value for a property with the data type item (e.g. property constraint (P2302)), the constraint definition of the allowed qualifier constraint is evaluated and shown in the suggester analog to the above.

Examples

Allowed qualifiers constraint definition on the property constraint property page

Supported constraint types

At the moment there are two constraint types that are used for generating suggestions:

• One-of constraint used for suggestions in the context of a main value.
• Allowed qualifier constraint used for suggestions in the context of qualifiers.
