== References ==
When either the <code>reference</code> or the <code>references</code> command is used and a reference is encountered (in Wikidata), the module checks if the reference contains an {{property|P143}}, {{property|P3452}} or {{property|P4656}} property. In the case one of these properties is present, the whole reference is ignored (i.e. it is treated as if it wasn't present).

Else, the module attempts to display the reference using the {{Tl|Cite web}} template. The reference has to have a {{property|P854}} property. The below table shows the mapping of Wikidata properties to parameters of Cite web.
<!-- The information in the table is from Module:wd/i18n. -->

{{Anchor|Ignored parameters}}The following properties are ignored: {{property|P18}},  {{property|P3865}}.

If there is no {{property|P854}} property present in the reference, but a property of the "External identifier" [[d:Help:Data type|data type]] is present both in the reference and in the {{property|1687}} of the item in {{property|P248}}, a URL is generated from its content and is used in the same manner as a URL given in {{property|P854}}.

If there is no {{property|P854}} property, or the reference has unknown properties, the module attempts to display it using the {{Tl|Cite Q}} template. The {{property|P248}} property is mandatory. The below table shows the mapping of properties to Cite Q parameters.

The properties listed ''under'' the first table (in this section) are also ignored when using Cite Q.

A reference could be displayed using Cite Q only if the reference has a {{property|P248}} property and has only properties listed in the table above. If neither Cite web nor Cite Q could be used to display a reference, the following an error message with an explanation is returned.

To fix this error, check if the reference has the required properties and doesn't have any unknown properties, as described above. The [[d:Help:Sources|Wikidata help page on references]] can also be helpful when sourcing statements.
