Hi Magnus!
That's excellent news! Thanks a lot!
I'm currently preparing a CSV dump of YSO places. Most of the entries
have coordinates. I will send it to you soon for inclusion as a catalog
in Mix'n'match.

Just to update everyone in this thread, I have added location support
for Mix'n'match. This will show on entries with a location, e.g.:
https://tools.wmflabs.org/mix-n-match/#/entry/1655814
All Mix'n'match locations (just short of half a million at the moment)
can be seen as a layer in WikiShootMe, e.g.:

Cheers,
Magnus

Hi Osma,
sorry for jumping in late. I've been at ELAG last week, talking
about a very similar topic (Wikidata as authority linking hub,
https://hackmd.io/p/S1YmXWC0e). Our use case was porting an existing
mapping between RePEc author IDs and GND IDs into Wikidata (and
furtheron extending it there). In that course, we had to match as
many persons as possible on the GND as well as on the RePEc side
(via Mix'n'match), before creating new items. The code used for
preparing the (quickstatements2) insert statements is linked from
the slides.
Additionally, I've added ~12,000 GND IDs to Wikidata via their
existing VIAF identifiers (derived from a federated query on a
custom VIAF endpoint and the public WD endpoint -
https://github.com/zbw/sparql-queries/blob/master/viaf/missing_gnd_id_for_viaf.rq).
This sounds very similar to your use case; also another query which
can derive future STW ID properties from the existing STW-GND
mapping
(https://github.com/zbw/sparql-queries/blob/master/stw/wikidata_mapping_candidates_via_gnd.rq
- currently hits a timeout at the WD subquery, but worked before). I
would be happy if that could be helpful.
The plan to divide the m'n'm catalogs (places vs. subjects) makes
sense for me, we plan the same for STW. I'm not sure, if a
restriction to locations (Q17334923, or something more specific)
will match also all subclasses, but Magnus could perhaps take care
of that when you send him the files.
Cheers, Joachim
