Hello Pernycek,
Ignoring Google Maps (Which we cannot use) and wikidata (usually likewise, for different reasons), what is your source for your edit here?
Best Regards,
Andy (from OSM's Data Working Group)

Ah - I see a comment on changeset/182785531 explaining the signage.

Powiedziałeś „przywróć błędną edycję kierunkową”, ale nie powiedziałeś, skąd to wiesz. Poprzedni redaktor powiedział: „Ulica Lubartowska jest dwukierunkowa na całej swojej długości”.
Bez żadnych konkretnych dowodów skończymy na wojnach edycyjnych w nieskończoność, takich jak https://map.atownsend.org.uk/maps/osm-deep-history/#/way/230504488.
Proszę, wyjaśnij, dlaczego masz rację, a drugi maper się myli.

You've said "revert incorrect directionality editing" but have not said how you know that. The previous editor said "Lubartowska Street is two-way along its entire length."
Without any actual evidence we'll end up with edit wars ad infinitum like https://map.atownsend.org.uk/maps/osm-deep-history/#/way/230504488 .
Please explain why you are right and the other mapper is wrong.

@Vojtěch Fošnár what is "sync dev"? If you're importing data into OSM you must follow osm.wiki/Import/Guidelines .

Hello,
Andy from OSM's Data Working Group here (we've been made aware of this discussion).
Outside the DWG I've spent quite a lot of time looking at what OSM tags are used with what other OSM tags. "attraction=animal" on an animal enclosure within a zoo doesn't usually have a "tourism=attraction" tag.
If you look at the tags that occur with "attraction=animal" https://taginfo.openstreetmap.org/tags/attraction=animal#combinations you can see that "tourism=attraction" is used in only a third of cases.
Quite a few of those are "standalone" animal attractions like node/6611980233 , not within zoos at all.
I'd actually suggest the forum https://community.openstreetmap.org/ as the best way to discuss this sort of thing.
Best Regards,
Andy

It looks like this edit broke a couple of cycle routes - see e.g. relation/11017#map=20/57.3458154/-4.0042718 .
Also, is way/37121135 really access=no currently?

Oops - looks like this broke a bunch of relations such as relation/11064743#map=20/53.3295359/-6.5297889 . I've split the bridge in two where the boundary joined and removed the extra bit from the 15 relations.
Personally I find editing relations in Vespucci very complicated (although the author of Vespucci does not - see https://community.openstreetmap.org/t/cloning-copying-a-relation-or-route/142949/15 ).
Cheers,
Andy

Also ts2761a (Walsden 509 bus) and ts2762b (Todmorden)

Here you say that https://map.atownsend.org.uk/maps/osm-deep-history/#/way/8692572 is no longer disputed by Morocco. What evidence do you have for that?

Here you have changed the name of https://map.atownsend.org.uk/maps/osm-deep-history/#/way/8692572 from a mulitlingual version to just Spanish. Did you discuss that with both the Spanish and Moroccan OSM communities?

Here you have removed a couple of alt_names from Parsley Island https://map.atownsend.org.uk/maps/osm-deep-history/#/way/8692572 . Can you explain why?

Also, what does the changeset comment "lines" mean?

Hello Muskovian and welcome to OSM.
Can you explain why you deleted relation/9520115/history here?

You've got "type=multipolygin" in here.
You could argue that "claimed_by" makes sense, but it is only claimed by one person: https://en.wikipedia.org/wiki/V%C3%ADt_Jedli%C4%8Dka , not any government.

Hello,
I've moved the Hertfordshire Way and the other signed paths over to the parallel riverside paths in changeset/183021991 - does that make sense to you?
Best Regards,
Andy

(no bats involved!)

For completeness: https://www.mastersofgames.com/rules/bar-billiards-rules.htm :)
It does see to be going through a bit of a revival. I was in the pub when the one at changeset/116037001 was installed.

Thanks: changeset/182968648

Hello,
Are you sure that this still exists? The links on changeset/154996123 suggest "missing, presumed sunk".
Best Regards,
Andy
