<div class="moz-cite-prefix">Good morning Yuri,<br>
<br>
On Saturday I added the Wikidata tag to the monument [1] of
Mikhail Bakunin [2] in Bern. In fact, I had added also the
monument itself on the map. I searched for it for quite some time
at Bremgartenfriedhof, as there was a typing error in the English
Wikipedia article concerning the box number (it is corrected
already).<br>
<br>
I also added some ground and aerial photos of the monument with
GPS coordinates to the Wikimedia category, published the GPS trace
to the OSM, and filmed a short video in English language:<br>

<a class="moz-txt-link-freetext" href="https://youtu.be/GCGdnFf8BDY">https://youtu.be/GCGdnFf8BDY</a><br>
<br>
and the same video in Russian:<br>

<br>
Quality on Youtube is better, as I could not figure out yet how to
convert a video to the WEBM format without some quality loss.<br>
<br>
I mean that in addition to validating by scripts the legwork also
have got a potential. In this respect, it would be helpful if we
had the Wikipedia & Wikidata layer on the OSM map, with an
option to see Wikidata items without an image, Wikipedia articles
in different languages, so a human may see, analyze, and visit an
object on the ground to clarify the situation. At the this point,
I would not dare to correct an OSM-Wikipedia inconsistency without
first visiting, recording a GPS trace, and filming it. So in my
opinion it should be on a map, in addition to a list.<br>
<br>
Some new hardware tools became affordable by now: precise
GPS/GLONASS trackers, video-cameras with stabilized gimbals for
ground and aerial filming, directional microphones. But also the
photo-cameras themselves became better. A human armed with these
new tools can do a lot of useful work at a location, though it may
take some time until we learn how to employ these tools
effectively.<br>

<div>TLDR: researching ways to validate wikipedia and wikidata

<div>I have been analyzing the quality of OSM's wikipedia and
wikidata tags by cross-checking data using both OSM tags and
Wikidata. My first goal is to fix "disambiguation" references
- when OSM object links to the Wikipedia disambiguation page,
instead of the real location page. I have already fixed about
200 objects, but there are about 800+ relations left, and I
could really use some help. I don't think its possible to add
them to MapRoulette just yet.</div>

<div>While fixing wd/wp tagging issues, I have been putting
together a list of open questions on how we want to improve
wikipedia and wikidata tags in general, and create some
guidelines. Lets discuss them in the talk page?</div>

<div>Lastly, if you have any suggestions on different ways to
validate data using the mixture of Wikidata and OSM, let me
know. At the moment I have a list of all types of OSM
objects' wikidata IDs, and mark the bad ones with a value. If
OSM's wikidata's "instance of" of one of the bad types, my
script puts those OSM objects it into a separate list that I
can analyze. The list of types is here - sort by the second
column:<br>

<div>Feel free to modify the second value of any row to indicate
that those objects should be fixed.</div>
