Модуль:PropertyLink

Документація модуля[перегляд] [редагувати] [історія] [очистити кеш]

This module can be used for advance linking, according to Wikidata. It includes the following functions:

• property - get a link according to wikidata claim

• • Parameters: property (e.g p123)
  • Example: in Lion {{#invoke:PropertyLink|property|p70}} - will give Carnivora. It is better to use this function and not [[{{#property:p70}}]] as the property gives the label in Wikidata, while this function will use the correct sitelink.
• label: gives the label in wikidata (no [[link]])
  • Parameters: property (e.g p123)
• imageLink: Get a related file to be used in the article
  • Parameters:
    • 1 param (optional) - Property to get commons link. If not specified it uses d:Property:p18 (a generic property for image in wikidata)
    • width - default 220px
