Could you check this node? It got a 'tion' tag:
node/9444785205

This seems to be an undocumented import of a huge amount of foreign data. Please check the Import Guidelines to see how such an import needs to be done.
osm.wiki/Import/Guidelines
For now, I suggest to revert these edits and start again from scratch.

Hallo,
schau bitte mal nach den recycling-Tags hier - da sind einige dabei, die so nicht definiert sind.
way/1064919078
amenity=recycling

Hi,
could you check these recycling nodes? Many of the recycling:* tags are not those listed in the wiki.

Hi,
you added 4 nodes with a strange tag here:
manh=d
Could you check & fix this?

Hi,
I found two nodes wih 'lrn_ref' tags - these are not used in any other place. Could they be replaced by some common tag?
E.g. node/1107586229

Hi,
I found 3 nodes with a 'lsm_ref' tag like this one:
node/3387522017

It seems like they could be merged with guideposts nearby or could make use of some additional tags?

Hi,
The fuel:* tags you used here are not the documented ones. Please have a look to the wiki and change them to common fuel tags:
osm.wiki/Key%3Afuel

Please don't use the OSM database to store your own, app specific routing data. Data either needs to be usable by everyone (including a proper documentation) or needs to be stored in your own private database.

Please check the fuel tags you added here - three of them are not used in any other place.

Thanks!

Hi,
you used the tag 'overtaking:bicycle' here.
Does that mean that bicycles are not allowed to overtake each other (that's what the tag means according to usual styles)? Or that cars are not allowed to overtake bicycles?

@GeoMechain: Is the revert of this huge import still planned? I guess this should be done very soon before too many people start to fix all the issues caused by it (e.g. wrong tags and POIs mapped twice). It affects about 1400 camping areas across France!

This looks like an import of boundaries from some unknown source. Please check the OSM import guidelines to see how imports of foreign data to OSM should be done:
osm.wiki/Import/Guidelines

All these 19000 objects don't seem to have any valid OSM tag, so I opt to revert them for now and to start a proper import.

Hi,
kannst du mal nach diesem Node schauen? Er hat ein irgendwie unpassendes 'monitoring:name' tag:
node/9715653671

Using JOSM to upload data is only the very last step of any import. Please read and follow the Import Guidelines linked above.

For now I'll remove this data again so that you can start again cleanly from scratch.

Hi,
what does 'sidewalk:left:marking_road' mean? This tag is not used in any other place.

To me this looks like a revert is necessary unless we get some feedback.

- the legal details of the source is unknown, but clearly not mapped by hand
- the overall building outlines seem fine, but buildings got randomly cut in half
- JOSM validator gives more than 200 errors and warnings
- many foreign tags
- no import documentation

Hi,
what does 'hoa' mean? This tag is not used in any other place.
way/1056124201

Hi,
it looks like something went wrong here. You added 24 nodes with a huge number of foreign tags that don't seem to belong in OSM. Could you check that?

Please check all your recent edits. You added hundreds of 'motor_car' tags. The correct spelling is 'motorcar'.
