Bonjour,
Merci, mais j'aimerais bien savoir faire ce type de changement en anticipant les conséquences. J'utilise Josm. C'est dans les relations, j'imagine ?

Merci, je me doutais du problème, je suppose qu'il fallait mettre à jour des relations, ce que je ne maitrise pas.
Cdt.

Well, I understand.
But I don't think "weather_shelter" is convenient. Maybe these historic dry stone made buildings don't have to be noted "amenity=shelter". Nobody can rest in these "capitelles".

I would say I am incompetent for all you are stating.
I would suggest to contact people who tagged these at :

I just think it's worth have these "capitelles" visible on the map ..

Maybe can you see here :

For my point of view, the important thing is :
amenity=shelter, in order to make these "capitelles" visible on the map.
