The point has been made by others that the namespace here is unnecessary. We know what length= means here so the climbing namespace is superfluous because what you are tagging is a climbing route. I haven't commented on the tags here previously but I'll give you my approach in case it's useful. So, for example, I'd work on the basis that: Bottom (start) of section is a node with appropriate information Top (end) of section is a node with appropriate information Start to end of section as one way (there may be more than one section in the route, some climbing and some scrambling etc). Relations can be used to group the whole route if required/desired. This is the same approach used currently for all other types of routes in OSM, climbing routes are no different. Then I'd start with the OSM basics. Probably with highway=footway first because it's not logically any of the other highway categories. Then add footway=climbing to denote that you wouldn't stroll along this route ;-) Now for the technical stuff: rock=limestone adjectival:gb= (assuming the same route at the same location requires alternative country grading, if it only applies within the country where the route is located then the gb would not be required) technical:fr= ewbank= yosemite_decimal_system= (sticking with plain language is better than abbreviations) bolted=true length=25m etc You don't need all the namespace stuff in front provided the footway=climbing is there in the tags. Then you know the way is a climb/scramble or whatever. Anything that has lots of namespaces, abbreviations or other non-obvious tagging names makes it much more difficult for data contributors to easily add tags. Simple and logical appears always to work best.
