Help:Property constraints portal/Value label

complex constraint value label (Q100884525) specifies that the labels of items used as values for a property should conform to a certain pattern in a given language.

It can be suitable for properties with item-datatype that have a distinct value constraint. It is different from format constraint applicable to string-datatype properties.

For example, the English label of values for category for the interior of the item (P7561) would generally start with the string "Category:Interior of ". This can be written with the regular expression Category:Interior of .+ and the language code en.

Contrary to standard property constraints, this constraint is added with has characteristic (P1552) on properties. As a complex constraint, it also requires the addition of {{Complex constraint}} to the property talk page.

The output is available only as a periodically updated report at Wikidata:Database_reports/Complex_constraint_violations.

Possible actions

The main report for the constraint violations allows top-down analysis and the correction of minor or systematic errors. It generally doesn't aim to achieve zero constraint violations. Sample corrections can be:

• fix uppercase/lowercase errors on items: e.g. items for the history of topic shouldn't be labelled "History of <topic>", but "history of <topic>". This is an initial cleanup generally needed for labels based on Wikipedia article titles.

• fix typos: e.g. ensure "geography" isn't spelled "gegography"

• It's possible that the label of another language was incorrectly added to the language being checked: e.g. the French label shouldn't use the English label. This can happen through manual or bot edits

• It's possible that the label incorrectly includes "Category:"

• It's possible that the label misses "Category:"

Also:

• It’s possible that the value is correct, but does not belong to this property, and that it should be moved to a statement for a different property: e.g. "Category:Films set in <place>" is added instead of "Category:Films shot in <place>".

• It’s possible that the property has expanded its field and the regex needs to be adapted.

A second report lists languages that have labels for the values, but no regular expression defined.

Parameters

This constraint has one mandatory and one optional parameter:

format as language specific regular expression (P8770)

Contains the format/pattern and the language code. It can contain one or several values for a given language. no value Help or unknown value Help are not permitted. It must be a valid regular expression.

syntax clarification (P2916)

Contains a human-readable description of the pattern. Can be specified several times in different languages.

Examples

Example 1

The labels of the values for category for the interior of the item (P7561) should start with Category:Interior of .+.

has characteristic	complex constraint value label edit format as language specific regular expression Category:Interior of .+ (English) 0 references add reference
		add value

Template

To define the constraint, {{Complex constraint}} with a SPARQL query needs to be added to the property's talk page.

This can be done by adding:
{{subst:Define value label constraint}}
