please review:
way 257485715 crosses the building?
Maybe a part of it is a tunnel=building_passage?

.. and way 314323861

similar:
way 314317311

please review way 314317302:
I've changed the invalid tag
highway=path;unclassified
back to
highway=path

please review:
way 303489122 has the invalid tag
highway=path;track
Please split the way at those points where the type changes and chose either path or track.

bitte prüfen:
highway=path;track
is ungültig. In Bing sieht es so aus, als ob
der erste Teil des Weges path und der zweite track ist.

please review :
way 234462105 had invalid tags:
highway=path;unclassified
surface=ground;paving_stones

me again ;-)
I have started to check the database
for new highway=* tags and it seems that you really like to invent new tags, so your work pops up on my list.
way 217569275 looks clearly like a
highway=service,service=driveway
to me, maybe maybe service=parking_aisle.
You use
highway=manoeuvring forecourt
(note the missing underscore)
highway_1=driveway
If you are concerned about the rendering
of your work you really should try to
use the well documented tags listed in the wiki:
osm.wiki/Key:highway

hmm, the bus relation seems to be broken now:
osm.org/relation/2898930

thanks, no offence meant.
You will notice that these roads are now rendered in the map.

well, I think highway=* should be used
for information that is relevant for routers.
I think the area shown at
osm.org/changeset/34598843
is landuse=residential, so
if you want to map the green you use natural=*

okay, thanks for the feedback

hmm, I am not sure if I understand. You seem to search for something like barrier=hedge?

yes, sure. I changed it to unclassified without any local knowledge .

please review the tags on the
power=tower node 310178067.
You probably wanted to change another object?

please review:
nodes with highway=trunk and junction=roundabout make no sense.
Not sure what was meant here.

okay, vielleicht bin ich zu blöd, aber warum zwei Wege mit genau den gleichen Punkten?

Danke. Das Problem ist eher iD, dieses Problem haben viele Anwender.

please review:
what does highway=declared mean?
Did you mean highway=footway or highway=pedestrian?

please review way 260288775,
I've changed it to highway=residential,
but the name might also be wrong
