This page collects and refines best practices for describing maps on Wikimedia Commons.

Are images of maps described in Wikidata or Wikimedia Commons?

See proposal on Talk page

What are the properties used for maps?

See the inventory of properties created at Wikidata:WikiProject Maps/Historical map properties. Let's copy them over and evaluate for each property how they should be used.

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

Maps without Wikidata item

This section describes some best practices for maps that are not notable enough to have their own Wikidata item.

• named place on map (P9664)

Examples

Futured desired state

• {{Map}} should import Wikidata metadata as {{Artwork}} does. (Planned, volunteer on board).
