Mòdul:Location

Aquest mòdul afegeix un referent entre parèntesis a l'etiqueta d'una localitat o unitat administrativa obtinguda de Wikidata. Per exemple: "Mataró (Maresme)" o "Berlín (Alemanya)". Utilitza com a suport Mòdul:Location/ca per la definició de criteris en català.

Vegeu la documentació a w:Mòdul:Location i els criteris usats a w:Mòdul:Location/ca.
