Enabling Wikidata suggestion for properties

Wikidata URI suggestions are enabled through Resource Templates. For additional information on Resource Templates, see the Resource Template Documentation.

  1. From the Resources templates tab in the Admin Dashboard, add a new template or edit an existing one.
  2. Add the property to which you want to apply Wikidata URI suggestion.
  3. Once the property is added to the template, click the pencil/edit icon for that property.
  4. At the bottom of the drawer, which opens on the right, open the Data type drop-down. Below the standard options, you will see the Wikidata options. Select the type of suggestion you want to use from the drop-down.
    • Note that you can also add alternate labels and comments for the property in this drawer.
  5. Click the Set changes button at the bottom of the drawer to assign the Values to the property.

Adding Wikidata URI to an Item

When this Resource Template is used in an Item or Item Set, the designated properties will auto-suggest values from the type of Wikidta item specified in the template.

Users must start typing in the open text box of that specific property to prompt the auto-suggest feature. There may be a slight delay, but a drop-down menu will appear with choices drawn directly from Wikidata.
