The oneway tag should only contain the value yes. The further information should go into different tags.

Look how OSM stored your data:
way/94446322

Hi and welcome to OSM!
Please review the nodes you created in this area. For example the tags for
node/4875071999 look completely wrong.

Hi and welcome to OSM!
I see that you are very active mapping house numbers :-)
Please don't create tags like addr:housename=a or addr:place=a
If you don't know the name just leave the field empty.
It would be much better if you add the corresponding street name using addr:street, for example this node
node/5008708221
should probably have addr:street=Lã Xuân Oai
Happy mapping!

Hi!
Please review the position of the rails at this node:
node/2365711704

I've now noticed that you moved all nodes of Makurdi to Zaki Biam Road by ~25m. I think this was not intended.
See my changes here:

Hi and welcome to OSM!
Please review the mapping of this footbridge way/154430617
See https://github.com/openstreetmap/iD/issues/4309
Do you know how this bridge is connected to the building in the west ? If I got that right this way way/154624126 is not the building itself but some kind of ring around the real building. It would also be good to map the connection on the eastern side. Is there a highway=elevator?

Hi!
Please review typo highway=Trou du Loup
on node node/4513495274

HI and welcome to OSM!
I've noticed that you changed a highway from unclassified to camino. The highway tag is used to map the importance of a road, e.g. footway or motorway. See highway=*
I think that way way/231157367
could be a highway=track like
way/231157359
or maybe a highway=bridleway if it is primary used by horse riders.
You also created some relations here. These are rather difficult elements in OSM and you probably do not yet know enough to understand the purpose.
I hope this helps and wish you happing mapping!

Hi!
I've changed the unusual mapping of the footbridge, see changeset/52163293
I guess you were mislead by iD, see also
https://github.com/openstreetmap/iD/issues/4309

Wird auch gerade hier diskutiert:
https://forum.openstreetmap.org/viewtopic.php?id=59786

Moin!
Mir ist aufgefallen, dass es den Spessart zwei mal gibt. Siehe relation/3894648
Die beiden beschreiben unterdessen fast exakt die gleiche Fläche, das soll wahrscheinlich nicht so sein, oder?

Hi!
Please check this junction:
node/4544152911
The roads are not connected.

Hi!
Please review this bride. See
https://github.com/openstreetmap/iD/issues/4309

Hi and welcome to OSM!
You mapped some roads with highway=unpaved here. The highway tag is used to map the importance of the road, not the surface. The roads seem to be for agricultural use, so I've changed them to highway=track. This implies surface=unpaved.
You also used building=yes for a place that seems to have multiple huts. Please map each single hut as building=yes or building=hut, and you can use landuse=residential to map the area around those buildings.
Hope this helps and happy mapping!

OK, so I guess that the sat image is outaged, See changeset/52108756
LPI NSW also shows a large building in the south of this place which doesn't appear in the map.

Neh, will ich auch nicht. Passiert anders wo auch immer wieder, weil halt JOSM meckert.
Irgendwo hast Du auch einfach alles entfernt, was nicht üblich ist. Könnte man hier evtl auch machen.

Yes, and another potential problem here is that one may confuse area:highway=service with highway=services + area=yes as in highway=services

Yes, area:highway is used by special renderers.
Looking again at it I think in case of relation/5673340
you really improved the mapping.
Sorry for the noise. I found other cases that IMHO did not improve the data, see changeset/47783387

Moin!
Warum hast Du z.B. hier
way/403882576
aus Area=0 area=0 gemacht?
Aus meiner Sicht war das irgendein Import, bei dem Area etwas ganz anderes bedeutet als area (=yes/no)
