Does anybody have knowledge about #openstreetmap data related to #climbing ? For example, this is a gym: https://www.openstreetmap.org/way/56016849 and this is a cliff: https://www.openstreetmap.org/node/3718329581

I would like to know what properties could be attached to this kind of nodes, how is #osm modelling this kind of data... I know basically nothing about the OSM universe but I would love to play with it a bit.
