Add GeoJSON to Wikidata/Wikimedia Commons/Wikibase with geoshape relationship

[nuest]

GeoJSON can be uploaded to Wikimedia Commons with the .map file extension and then be included in pages, as described here:

https://www.mediawiki.org/wiki/Help:Map_data

https://www.wikidata.org/wiki/Wikidata:Map_data

For testing it is unclear though if this file upload works for Wikibase-instances, too.

Relationship geoshape: https://www.wikidata.org/wiki/Special:EntityPage/P3896

It is unclear if we can test with with wikibase.cloud or not - wait for email reply on wikibase-cloud@lists.wikimedia.org

Not possible on wikibase.cloud > https://lists.wikimedia.org/hyperkitty/list/wikibase-cloud@lists.wikimedia.org/thread/Z5ETMWEKEFI6GFWBKJKZSXXJXVL2EVB4/

Need to test with Wikidata/Wikimedia Commons directly (the letter has a personal test space though).
