some info for the planning :

> .... Wikidata names. I'm guessing thats because they are simply better
quality,

most of  the labels /names generated/transliterated  by bots ..
or imported from other databases ( GeoNames !! )

> better modeled, better referenced

Wikidata:  The Cathedral style ... top-bottom
OpenStreetMap:  Bazaar style data model:  ... bottom-up

in the OSM .. There are a lot of name tags :
https://taginfo.openstreetmap.org/search?q=name
and it is not easy  to map everything to the wikidata model.

Wikidata is a graph database .. and there is a "known" scalability problem
https://lists.wikimedia.org/pipermail/wikidata/2019-June/013124.html

*"Scaling graph databases is a "known hard problem", and we are reaching*
*a scale where there are no obvious easy solutions to address all the*
*above constraints. At this point, just "throwing hardware at the*
*problem" is not an option anymore."*



can't protect against bad import ..  no strict  community rules ...
for example -  the cebwiki  re-imported the full GeoNames database ...
https://www.wikidata.org/wiki/Wikidata:Project_chat/Archive/2018/06#A_proposed_course_of_action_for_dealing_with_cebwiki/svwiki_geographic_duplicates
https://www.wikidata.org/wiki/Wikidata:Project_chat/Archive/2018/07#Another_cebwiki_flood%3F
https://www.wikidata.org/wiki/Wikidata:Project_chat/Archive/2017/10#Cebuano

> and better protected against vandalism.

anyone can modify the wikidata - without registration.
in the wikidata JSON dump - no user info .. so it is hard to detect the
modifications type ( from logged or unlogged users )


Best,
 Imre
