Hi yosiken,
why do you add a line to the center of a building polygon?
It is not rendered and OSM Inspector
http://tools.geofabrik.de/osmi/
considers them as self-intersecting.

okay, thanks

please review:
no tags on outer way or mp-relation
after this change.
relation 1466957

schon klar, ich wusste nur nicht,
ob irgendwelche Tags beabsichtigt waren.
Danke!

thanks, I'll fix a few more problems in this area

Bitte prüfen:
node 307195771
hat diverse seltsame tags bekommen,
z.B. highway=secondary

Okay, danke

This created the uncommon highway=m
tag for way 318017027
Intended?

please review:
this change produced two ways with
invalid highway=service;unclassified
tag

please review:
this change produced many
highways with name
name=Via Toniolo
and maxspeed=50, many of them
service ways

start JOSM, download the data around this area. Make sure to have the Validation Window (see Windows->Validation Results) open and click on Validation. See also
osm.wiki/JOSM/Validator

please review, the expected format
is incline=1 %.
not highway=incline(1)
See http://taginfo.openstreetmap.org/keys/incline#values
and
osm.wiki/Key:incline

JOSM still reports a lot of errors here.
I am not sure how well iD supports
restrictions. The typical restriction
has a from way, a via node, and a to way.
The from way must end at the via node,
the to way must start at the via node.

please review
this change produced some nodes
with wall=yes .
What does highway="no_parking_1-15"
mean?

this change produced some invalid
route restrictions. I tried to guess
what was meant near
node 3607052485

please review,
ways have strange highway tag:
way 372855523,way 34869184

I guess this was meant to add a name
iinstead of setting
highway=Heritage Place ?
I'll change it that way.

maxspeed=sign should give a numerical value
way 3726331,way 248793312,way 173806937,way 173806951,way 173806929

way 183750734:
maxspeed=21.841, 96.067
looks like a typo.
I assume it should be "maxspeed=60 mph"
?

please review:
this change produced an invalid
turn restriction in
