Hi!
Please check highway=turning_circle on this way way/173271995.
I guess you wanted to change a different object?

Hi!
I've noticed this changeset because of the typo highway=residental (missing 2nd "i").
I assume that JOSM has saved this wrong spelling and uses it whenever you start typing r e s , so please watch out to correct it. I've changed 23 ways here:
changeset/54325730

Yes, the wiki is not very clear about the destinction of unclassifed and residential, and I am also often unsure which is better when mapping in Japan.
When you follow this wiki: highway=* for unclassified it says
"The least most important through roads in a country's system – i.e. minor roads of a lower classification than tertiary, but which serve a purpose other than access to properties. Often link villages and hamlets."
The given example serves to access properties, doesn't it?

Hi!
I noticed this changeset because of the typo highway=u here:way/543539978
I changed it to residential.
I wonder why you map the residential roads with highway=unclassified?

Hi!
Why did you change the tag highway=path to highway=trak
on this way :way/69082540 ? This tag is only used here and the previous value seems to be appropriate.

Ich habe das unübliche highway=stairs nach highway=steps geändert.

Hi!
Please check: What is meant with highway=mwembeni ?

Wie gesagt, ich kenne mich mit indoor mapping nicht aus. Schwierig ist es, weil man oft mehrere Linien übereinander legen muss und dann ist die Auswahl der gewünschten Linie nicht mehr so simpel.
Ansonsen kann ich nur auf osm.wiki/Simple_Indoor_Tagging
hinweisen und natürlich solltest Du alle Meldungen des JOSM Validators prüfen.

Hi!
Please review: What is meant with highway=kn on way/543293274 ?
Why are the footways in this area not connected to e.g. way/146623134 ? Instead they are connected with (end at) the landuse area.

Hi and welcome to OSM!
I've noticed this changeset because of the unusual tag highway="Ngô Sĩ Liên, KDC Metro"
I assume that "Ngô Sĩ Liên, KDC Metro" is the name of a residential road, so you should use
highway=residential + name=Ngô Sĩ Liên, KDC Metro
See also highway=*
Hope this helps, happy mapping!

Hi!
What did you try to map with this way?
way/543090675
Normally the tag highway=traffic_signal is used for a node on a highway=*.

Moin und willkommen bei OSM!
Du hast Dich als OSM Neuling mit indoor Mapping ja gleich an ein ziemlich schwieriges Thema rangewagt ;-)
Ich kenne mich mit dem Thema nicht aus, aber highway=staiway ist seltsam.
way/543042483
Meintest Du room=stairs?
way/543061358
hat room=stairways ,wahrscheinlich auch besser room=stairs.
Auch indoor="area=room" sieht falsch aus:
way/541039967
In welcher App schaust Du Dir die Daten an?

Hi and welcome to OSM!
You used the tag highway=crossing for a way here. The tag is only meant for nodes shared by a major road and a minor way (footway / cycleway).
So, if there is a crossing (no bridge or tunnel), please make sure that the minor way and the major are connected and tag the shared node with highway=crossing and additional tags that describe the crossing. If the minor way is a footway, use highway=footway + footway=crossing, else highway=cycleway + cycleway=crossing. Hope this helps?

Hi!
Why did you add the tag highway=* to this church?

OK, did you also understand that highway=private is very unusual?

Please add surface=* as well, as the meaning of surface:grade=0 is only clear when the surface is known.

Hi!
Please review: You changed a highway=living_street to highway=living street here. way/323692418
I suggest to use something like was:highway=living_street instead, as your tag looks like a simple typo.

Hmm, not sure what you changed but way/305486812
still has the same tags.

Hi!
I changed typo highway=Path to path here:
changeset/54091396

Hi and welcome to OSM!
I've noticed this changeset because of the unusual tags like highway=Hẻm 479
used here:
way/542690408
I assume that "Hẻm 479" is the name of the road and
In this case you should use name=Hẻm 479
The tag key highway gives the type of road, in this case probably highway=residential. See also highway=*
If you want to map access rules see access=*
but this is rather complicated for a beginner.
Please correct the data and continue.
Happy mapping!
