Hi matildap,
welcome to OSM. You took quite some effort to map buildings, but the tagging needs to be revised. E.g. you put these tags on one of the buildings:
building=subdivided house
carparks=0
dwellings=10
period=2000
The building-Key only uses well defined values, see building=*
building = apartments might be appropriate here. The other three keys do not exist as keys in the OSM-world yet. As long as they are not documented in the OSM wiki, they are rather useless as no software and no user is able to interpret them as intended.
Also, name = Garage is not correct - to mark a building as a garage, just use building = garage.

In case you have some questions, don't hesitate to ask either here, via PM or in the forums!
Enjoy OSM,
Jan

Hi,
I found a way with two maxspeed tags:
maxspeed:forward = 35 mph
maxspeed:forward_1 = 40 mph
way/399867361

Could you check which of the two is correct?
Cheers, Jan

Hallo,
zu diesen Fahrkartenautomaten habe ich ein paar Anmerkungen:
- was heißt "opening hours=?"
- "opening_hours" hat eine festgelegte Syntax. "Sonntags geschlossen" gehört nicht dazu
- operator ist sicher nicht ein Schreibwarenladen sondern die Verkehrsbetriebe
- Fahrscheinvorverkaufsstelle ist kein Name sondern eine Beschreibung, die bereits durch die Tags amenity und vending gegeben ist.

Gruß, Jan

There is a second one in another changeset: way/400694894

Hi Marcott,
way/400695134 ( way/400695134 )
has a lot of tags from some other source. Were these uploaded by mistake?
Cheers, Jan

Ok, I just removed them.

Hi Rps333,
did you really want to upload this way with a lot of foreign tags or was it a mistake?
Cheers, Jan

Hallo andrekoe,
diesen Gebäuden mit Hausnummer fehlt die Angabe einer Straße. Ich kann leider nicht erkennen, welche das jeweils ist. Kannst du da noch einen Blick drauf werfen?
Gruß, Jan

Hallo Filosm,
rund um den Heinrich-Böll-Ring und Kleistweg hat dieses changeset ein ziemliches Chaos an Adress-Nodes angelegt. Räumst du da noch auf?
Gruß, Jan

You can search for your edits using Overpass Turbo:
http://overpass-turbo.eu/s/evW
Using "Export" you can load these nodes to an editor (iD is not supported) and delete them. If you need assistance, don't hesitate to ask.
Jan

Hi Guillaume,
can these nodes with gibberish key / value be deleted?
Cheers, Jan

Hallo Klaus,
an der Klappergasse hast du vier Häuser eingetragen denen die addr:street fehlt. Ist das Klappergasse oder Schmalwiesenweg?

Is the UK law really this specific? Horses are forbidden, but a mule would be ok?

Apart from that: I think that many people are not aware that there might be a difference - as access tags are quite important, I guess there should be a proposal explaining differences and finally add this to the list of access tags.

Hi,
in other places I saw carriage=no used for exactly this traffic sign (which exists in other countries as well).
You could add some conditional restriction, because I doubt the "horse_drawn_vehicle" will be understood anytime soon by software, e.g. vehicle:conditional = no @ ("drawn by horse") - this can be understood by software as a restriction that can be displayed to the user to evaluate the meaning of the text.

Moin,
die Hauptstraße (75110820) hat jetzt
maxspeed:backward=50
maxspeed:backward_1=30
da stimmt doch was nicht ;-)
Gruß, Jan

Hallo,
ist es wirklich notwendig gleich 22 neue Keys zu erfinden um diese (anscheinend nicht in Wirklichkeit vorhandenen) Informationen in OSM abzulegen? Es sollten normalerweise nur solche Keys verwendet werden, die vorher durch ein Proposal vorgestellt und im Wiki dokumentiert sind. Mit solchen undokumentierten und aufgrund ihrer Komplexität auch sehr schwierig auszuwertenden Keys kann keine Software etwas anfangen.
Gruß, Jan

Hi Robert,
a "horse_drawn_vehicle" - isn't that what the wiki defines as "carriage"?
access=*
Cheers, Jan

Hi coopermj,
I found these strange tags on this way:
miamioh-lds=uitcp
miamioh:lds=uitcp
miamioh_lds=uitcp
is there any meaning behind that?
Cheers, Jan

Hi Hendrik,
could you check this way? It does not seem to be 150m wide and almost 8 km long. If the length is in feet, the unit needs to be specified. osm.wiki/Map_Features/Units
I would prefer to use the keys length, width and maxweight without the "runway:" prefix - they are not used in other places and there is no need to specify that it is the width of a runway as this is already given by the main key of the way.

Cheers, Jan

Hallo Alex,
hier scheint es einen Fehler mit Adressen zu geben: note/511108 "Am Erdbeerfeld 25" scheint das nicht zu sein.
Gruß, Jan
