Hi,
you used several keys here that are not used in any other place - what do they mean?

Karta Łodzianina = yes
diet:veger = yes
discount:citycard = yes
ŁOT = no

In OSM we have to use a well-defined set of tags to allow all the software tools to understand the data and e.g. show it on maps.
Also, our database in case sensitive, all keys have to be in lower case (with
very few exceptions). Please have a look to the OSM Wiki to find out which tags are in use.

Please watch out for the correct spelling. I fixed many "messsage" tags in the past days/weeks.

This huge import created tens of thousands of wrong tags.

It's "addr:postcode", not "addr:postalcode".

Where can we find the Wiki documentation and discussion of this import?

I did the same on the master relation already.

I could have used the more neutral "was:" instead, but I think 'disused' is fine here.

As you say, such a tag should only be added to objects that are actually 'disused', and not just vanished. A bus route that is not used for several months is a perfect edge-case.

Please check this relation, something went wrong with the url tag:
relation/12546589

"sidewalk:right:oneway:bicycle" meinst du? Das hat effektiv die gleiche Bedeutung wie sidewalk:right:oneway, ist nur unnötig lang und spezifisch.

Übrigens müsste es "sidewalk:right:bicycle:oneway" heißen, um bei der üblichen Reihenfolge Key-Seite-Fahrzeugtyp-Subkey zu bleiben.

Nein. "oneway" an highways bezieht sich nicht auf Fußgänger - sonst dürften die in keiner Einbahnstraße in beide Richtungen laufen.

Für Fußgänger gibt es "oneway:foot", bzw. an Routen-Relationen (z.B. hiking) auch ein einfaches "oneway", weil es da keine Verwechslungsgefahr gibt.

Hi,
you added the tag 'motr' several times - could you check and fix this?

Hi,
please check your edits. You used the tag 'airway' many times - but this tag doesn't exist. I guess you wanted to add some 'highway' tags instead.

Hi,
could you check the buildings you added today?
There are plenty with a "USE1_DESC=Residential" tag that looks like a mistake.

I changed a few, but not all of them. Here are the remaining ones:

I can do the changes in the next days.

There is no such "approval" implemented in JOSM.
JOSM only checks for a few well-known tags and if you added something that looks very similar (and even this check fails regularly).

Diese Gebiete haben alle falsch geschriebene Tags: protect_cl und short_prot.

Die Lage der Gebiete passt auch nicht zu bereits gemappten Objekten, teilweise laufen die Grenzen 50 Meter neben bereits bestehenden Landesgrenzen.

Hier muss einiges nachgearbeitet werden.

Please watch out for the correct spelling of tags - it's "toilets:num_chambers", not "toilets:number_chambers".

Please change the tags you added here as well.
And, please don't create relations with just one member like this one:
relation/12548693
These are not necessary, just add the tags to the building itself.

Lastly, the colour of a building should be 'building:colour', not 'colour'.

Yes, that would be correct.
Unfortunately there aren't any Mapillary images of this sign yet, otherwise I could have changed that myself.

Hi,
what does 'whm_enddate' mean? This tag is not used anywhere else. Is whm an abbreviation?

Hi,
could you check this way? "destination:green" looks like a mistake.
way/481197535

Hi,
there are 22 "payment:linepay" tags which seem to point to the same payment scheme. Could you check that as well?
