There is also an other nice example to extract coat of arms by using
Wikidata, this was in the past a too difficult task by analysing
Wikipedia-articles. The coordinates coming in this example from
OpenStreetMap and works only for OSM-objects that are connected with a
wikidata-tag.

It shows nicely what is possible with Wikidata and maps.
