Best practices

Maps with Wikidata item

This section describes some SDC best practices for maps that are notable enough to have their own Wikidata item in addition to having image files in Commons. These will often be maps in GLAM collections.

• Notable works
  • Wikidata item
    • image (P18) - points to Commons image file (see below)
    • depicts (P180) - holds depiction statements
  • Commons file
    • digital representation of (P6243) - points to Wikidata item (see above)
    • depicts (P180) - points to Wikidata item (see above) - No further P180 statements

Examples

(list files below that provide best practices on how to model various situations)

• 
  William Smith Sloane MS 2596 f15 Canterbury.jpg Example 1 of good SDC data modelling of "map-like" drawing with Wikidata item. This example uses Template:TL to import Wikidata metadata until such time as Template:TL is updated to do so.
• 
  MTN25-1042c2-2017-Berchules.jpg Example 2 of good SDC data modelling for maps without own Wikidata element. This case models series of official national map series of Spain.
