It's the local (Nepali) name for this place. I have changed from name:en to name:ne. Was that the right procedure to do?

I changed it accordingly.
It's not a natural cave, but a stone shelter built under a big rock, which can be entered by a door. It is commonly used by collectors of yarsa gumba throughout the season, but most of the year it is free.

It's the lokal name there, Marma probably refering to the area and odar to a local word for cave.
