<div class="m_7577784430243977716moz-cite-prefix">Certainly a tool to check and correct
obviously broken or duplicate wikipedia=*, wikimedia_commons=*,
wikidata=* links from the OSM map would be very useful. <br>
<br>
However, I've met inconsistencies which could be noticed only by a
knowledgeable human on the ground. For example, this <a href="https://fr.wikipedia.org/w/index.php?title=Chapelle_Notre-Dame-des-Voirons_de_Bo%C3%ABge&diff=121789421&oldid=121556970" target="_blank">coordinates
correction</a> for the chapel <a href="https://fr.wikipedia.org/wiki/Chapelle_Notre-Dame-des-Voirons_de_Bo%C3%ABge" target="_blank">Chapelle
Notre-Dame-des-Voirons de Boëge</a> . Before this correction it
had wrong coordinates placing it erroneously on absolutely another
mountain. I could correct it reliably only after actually visiting
this chapel for making some photos for its article.<br>
<br>
The comprehensive solution would be to have a dedicated Wikipedia
layer on the OpenStreetMap. Now we have Standard, Cycle,
Transport, and Humanitarian layers. Why not Wikipedia layer
similar to <a href="http://ausleuchtung.ch/geo_wiki/?lat=46.18824490036672&lng=6.177406311035156&zm=14&lang=en&ds=wiki&rd=10" target="_blank">this</a>
, so that a user can select Wikipedia language and see the
geo-markers corresponding to Wikipedia articles on the map. Or see
clickable geo-markers corresponding to wikipedia=*,
wikimedia_commons=*, wikidata=* tags.<br>
<br>
This tool is using MediaWIki API and Overpass API, but for the OSM
Wikipedia layer the data could be pre-calculated and synchronized
periodically in order not to overload the APIs.<br>
<br>
In fact, I am using the OSM map mostly with Wikipedia markers. For
example, I was recently on a short holiday trip to Stockholm and
the first thing I do I look what Wikipedia articles <a href="http://ausleuchtung.ch/geo_wiki/?lat=59.324472209890146&lng=18.0710506439209&zm=16&lang=en&ds=wiki&rd=10" target="_blank">exist
for the city</a> to select places to visit and to read about. So
in my opinion, such a Wikipedia layer would be kind of synergy, -
the creation of a whole that is greater than the simple sum of its
parts. <br>

Nice work.
<br>
I'm interested in make such validation a service, to identify and
fix any inconsistencies between OpenStreetMap and
Wikipedia/Wikidata.
<br>
I'll be working on that on the next days.

To my knowledge, there is no site where one could add a set of
OSM IDs
<br>
that need attention (something like a bug tracker lite, where
one could
<br>
come and randomly pick a few IDs to fix), so I made a few
tables:
<br>
<br>
List of Wikipedia tags that do not resolve to Wikidata tags.
Most of the
<br>
time, the WP tag is incorrect, sometimes it was deleted, and
very rarely
<br>
there is no matching Wikidata item (needs to be created by
hand).
