Hi there and welcome to OSM!
I've noticed that you mapped a road with
highway=main_road. This is very unusual,
I've changed it to highway=residential.
The old value unclassified was indeed wrong. See this wiki for more info:
highway=*
You have also mapped
addr:street=Albert Street
for this cinema:
way/393316821
I did not find a road with that name, please add it or correct the address.
The cinema should also be tagged with
amenity=cinema, see
amenity=cinema

Danke. Mich würde trotzdem interessieren, wie es dazu kam, egal ob Versehen oder Missverständnis.

Thanks for the feedback. The wiki also documents highway=cycleway + cycleway=crossing. See the first sentences in the wiki:
crossing=*

Moin!
Was bedeutet ein highway=turning_circle an einem building=yes ?
Ich sehe das immer mal wieder und hab' keine Idee...
way/393066772

Hi there!
You used highway="Impasse des Bernards"
here, I've changed that to highway=service + service=driveway + name="Impasse des Bernards"
See
way/393285972
Bing doesn't show a way there, so I am not sure if I got that right.

Hi there!
What was meant with highway=passing_place
on a way? I guess this was a typo, so I changed it to track. See
way/392861058

Hi Emilio,
I've noticed a few nodes with highway=give_way + side=*,
e.g side=right or side=both
What does that mean ?
Is it about the position of the traffic_sign?
E.g. at this roundabout:
way/186669074

Hi there!
You used the deprecated tag highway=byway here. Was that intended ?

Hi there and welcome to OSM!
You have created a few ways with tags like
highway=yes
or
road=secondary
or
Roads=yes
If you want to map roads, please use
highway, not road or Roads.
If you don't know the correct type of the road, please use highway=road.
See also
highway=*

OK, thanks for the feedback :-)

Hi there and welcome to OSM!
You have used highway=crossing for some footways. Please note that those ways should be tagged
highway=footway + footway=crossing
The tag highway=crossing should be used for the node that is shared by the footway and the major road.

I see. Another point:
access:bicycle=* should be bicycle=*,
access:psv should be psv=*
I think these tags were used long before the namespaces like maxspeed:forward=50 were invented.
See access=*#Examples

Hi there and welcome to OSM!
highway=footpath
is rarely used. Did you mean path or footway?

Hi there!
The attribute highway=busway is rarely
used, was it intended ?
way/393032849

Ok, thanks

Hi there!
You changed a highway=residential
to the unusual
highway="Via sin nombre"
Was that intended ?
If the really road has no name you can use noname=yes

Hi there!
You created some ways with
highway=purposed here.
Did you mean highway=proposed ?
Gerd

as I said, I am not a local and I don't know the correct attributes, I just noticed the typo.

well, whatever you decide should be better than highway=s ;-)

Thanks for the feedback :-) and happy mapping as well!
