Hi,
you used many new healthcare tags here that are not used anywhere else.

Instead of e.g. healthcare:speciality:infectious_diseases the more common tag is
health_specialty:infectious_diseases

I suggest to change all the tags to the "health_specialty" namespace.

Hi,
welcome to OSM! I looks like you tried to add a bus route here. Unfortunately the way you did it is not quite right - we can't add a new line on top of the map, but we need to add a relation that makes use of existing ways.
The tagging scheme is described here:
route=bus

The best way to learn how its done is to look at existing bus routes, they should be easy to find.

If you have questions, the best place to ask for assistance is the OSM community forum.

Having a relation as member of a route-Relation is quite uncommon, but I think there's nothing that forbids it. It might be better to add the ways directly (copy and paste should work in JOSM).

We don't have many running routes yet, so support is limited. You can always display an individual relation using the OSM Relation Analyzer or use Overpass Turbo for all routes in a given area, like so:
http://overpass-turbo.eu/s/1xuV

You also might want to file a feature request e.g. for waymarkedtrails at https://github.com/waymarkedtrails/waymarked-trails-site/issues

Hi,
at least LRP and ULP didn't exist before your edits, e.g. here:
node/2309915547/history

Hi,
please review the tags you added across France - you wrote "chemial_toilet" instead of "chemical_toilet".
http://overpass-turbo.eu/s/1xru

I checked the footprints of buildings: The validator shows 100 errors and more than 3000 warnings about the geometry. Many of the objects don't fit with what is visible on aerial images. I'm going to revert these edits for now. Please feel free to import the objects again after all necessary clean-up and sanity checks and after you consulted and fulfilled the OSM Import Guidelines.

Hi,
please check the fuel tags you edited here. There are several that are not documented and not used in other places:
fuel:D500 = yes
fuel:LRP = yes
fuel:ULP = yes

Hi,
please check the tags on this way.
- there shouldn't be a "side" in the parking tag - has to be replaced with left/right/both

- the two 'footway' tags seem like they should be 'sidewalk' instead

Hi,
you used the new tag "alt_route" here - it's rather unlikely that this tag will be understood by any application. I suggest to duplicate the relation to have separate ones for mountainbiking and running.

Hi & welcome to OSM!
what is the meaning of the tags you added here?
average Speed
Average Speed
average speed

Please use only those tags that are described in the Wiki or those that are available in presets in the editor. Only these tags can be understood by other users and applications.

Hi,
something went wrong here. You uploaded a huge amount of objects with strange tags like "confidence".

Where can we find the required documentation of the import?

Hi,
something went wrong here. You uploaded a huge amount of objects without any proper tag.
What is the source of all this data?

Hi,
you added some areas here, but they don't have any valid tag. Could you check that and add the correct tags for boundaries?

Hallo,
ich habe gerade ein paar destination-Tags korrigiert. Die richtige Reihenfolge im Key ist
destination:symbol:lanes:forward
und nicht
destination:lanes:symbol:forward.

I guess lane_markings is the correct one in this case...
A group from Berlin put quite some effort to develop some detailed cycleway tagging scheme, but unfortunately it is written in German:
osm.wiki/Berlin/Verkehrswende/Radwege

There's also the draft of a proposal:
osm.wiki/Proposal:Separation#Symbolic_separation:_marking

I think this scheme is quite good, just needs some finalizing.

Hi,
the tag "cycleway:right:lane_markings" is not yet used in other places. Is there some difference to "cycleway:right:marking" which is already used by others?

Hi,
I found some new keys "label_date" and "print_date" here - what is their meaning?

Hi,
you added the tag "name:rcrh" here - this does not seem to be a valid language code. Could you check that?

Hi,
what does "Artificial Intelligence = yes" mean? This tag is not used in other places.

If you create new tags, please keep in mind that they should not contain spaces or uppercase letters.

Thanks for the explanation!

The problem is, "left" refers to the left side of a way, but can't be used on nodes.

I suggest:
maxspeed:conditional = 20 @ (turn = left)
