OpenStreetMap

Hello,
I think that something has gone wrong here. You've set the wikidata ID of both osm.org/relation/195384 and osm.org/relation/88077 to https://www.wikidata.org/wiki/Q23098 .
They're different entities on the ground. Can you explain how you actually did the matching, and what you're actually trying to do here?
Best Regards,
Andy

Likewise osm.org/relation/957520 and osm.org/relation/957519 have been assigned the same wikidata ID. In this case should they perhaps share one relation that has the same wikidata ID?

SomeoneElse, thanks, good catch. I'm trying to get the Wikipedia and Wikidata tags in sync. Seems that the Wikipedia tag have been set to an identical value on both. I will investigate - maybe only one of them should have it?

SomeoneElse, I fixed the first one - it should have had a different Wikidata ID, as well as a different (more prescise) Wikipedia link. osm.org/relation/195384 I cannot figure out why the second pair have identical WP and WD links, without being identical. The WP article doesn't give any details either.

Thanks - the Administrative Derbyshire's wikidata link looks OK (the sv:wikipedia page looks a bit rubbish, but we'll gloss over that - a wikipedia problem, not an OSM issue).
As things currently stand I don't think osm.org/relation/957520 and osm.org/relation/957519 have a wikidata entry at all - arguably they should be one relation in OSM. The wikidata entry https://www.wikidata.org/wiki/Q2876117 actually claims to be for a village (not a civil parish), even though it was created from a wikipedia page that was for both "a village and civil parish ". Most of the civil parish ones in this changeset look similarly wrong; for example osm.org/relation/957808 is Dunham on Trent civil parish, the wikipedia link is for "a village and civil parish" and the wikidata entry is for a "village in United Kingdom". To be clear, the village osm.org/node/1782116865 and civil parish osm.org/relation/957808 are different entities in OSM; I'd expect them to have different entities in wikidata too, and I'd expect you to need to create the relevant entities in wikidata before linking to them.

Hi, thanks for looking into it!
The first issue is really about Wikipedia vs Wikidata linking -- sometimes WP article covers both the village and civil parish, while WD item claims it is both, but it is really about just one meaning. Do we really want to link to both is an open question - IMO only WD link is needed, as it is more precise, and WP can be extrapolated from WD. On top of it, there are already tens of thousands of incorrect WP links in OSM, while WD is much more stable, making WD much more desirable.
In a way, having multiple rels with the same WD ID is not really wrong - because there is always 1:1 between WP and WD, so if there was a WP link, it implicitly had a WD link as well. Specifying a more exact WD is, of course, an improvement of the data quality that is clearly a goal.
Is there a way to query for multiple relations that share the same WD id? This would be useful to sort them out.

Re "Do we really want to link to both is an open question" it would probably make sense not to link to either if the thing that you're linking from in OSM is something else entirely. To be honest, I'm still struggling understand what I asked at the top - "what you're actually trying to do here". Can you explain why (in the case of Dunham-on-Trent) you've linked the civil parish relation to the village entry in wikidata but not the village node to anything?
To answer the question of how to query for multiple relations with the same wikidata entry, it might be worth starting with taginfo http://taginfo.openstreetmap.org/keys/wikidata#values . The first 857 pages have more that one item with a value. To see duplication in an area, select a value and click the overpass link to see the things that have that value.

I posted a long reply to https://forum.openstreetmap.org/viewtopic.php?id=56436 but it is pending moderator approval. I tried to explain both my method and reasoning. I simply locked the volatile Wikipedia link as a Wikidata ID - I have not touched the objects that did not have a Wikipedia tag already. Having a wikidata id on the object would allow it to be inserted into wikipedia article - https://www.mediawiki.org/wiki/Help:Extension:Kartographer#GeoShapes_external_data

Thanks - I'm sure that the post will be approved shortly.

SomeoneElse - https://forum.openstreetmap.org/viewtopic.php?pid=618646#p618646

fixed two more dups - osm.org/changeset/43815558 - the rest (957519,957520 - Barnby Moor CP, and 1976182,4077796,1976184 European walking route E2 - seems legit. We don't need to have a perfect 1:1 between wikidata and osm - just like WP links, multiple objects in OSM can point to a single object in WD.

It's been over 3 weeks now - are you going to fix the errors in this changeset? Some examples noted above, but there are many others.

SomeoneElse, yes, I am working on it. You can always reach me on IRC - "yurik".

Well, It's been over 5 months now - are you going to fix the errors in this changeset? The Dunham-on-Trent example is still wrong, but there are many others.

Actually, looks like someone's changed something in wikidata back in April - wikidata now says "village and civil parish". Barnby Moor still in 2 pieces though (wigh pre-exists this changeset).

@SomeoneElse, I think it should be fixed differently - we should remove all tags except name, note, source, and type, and create a relation that has all the original tags with those two ways.
