A specialized camping map could see from the data which features are available on a certain site (because this information is spatially available) On the other hand this requires some processing / advanced querying and might be too expensive for general maps, so a basic scheme with rough site types for the camp site object ((1-2 attributes should be sufficient) seem reasonable as well.

If you have put everything on 1 node it's a pretty useless map, not ? +1, IMHO the ideal mapping should be an area for the camp site, and features should be mapped inside this area as objects on their own (i.e. no need to repeat those as attributes on the camp site). A specialized camping map could see from the data which features are available on a certain site (because this information is spatially available) On the other hand this requires some processing / advanced querying and might be too expensive for general maps, so a basic scheme with rough site types for the camp site object ((1-2 attributes should be sufficient) seem reasonable as well.

Re: [Tagging] Tagging method of amenities at camp_sites
What do I see on the map when I use the stacked amenity model? A campsite symbol with a restaurant below it or a restaurant symbol with a campsite below it? A search in OsmAnd will give me the campsite in all cases, but it cannot always show all tags below it, so I don't know all amenities by looking at the node. If I have separate nodes I always see them all. If I (roughly) know the camping perimeter I can place the amenities as nodes or buildings within them. Having three nodes close together but not at the exact location is not worse than having a single stacked node which isn't a the exact place either.

This is a spinoff of a discussion that was started in the mail trail about the proposal for camp_site=* that is currently open for comments.

Re: [Tagging] Tagging method of amenities at camp_sites
I like the values you proposed (the camp_site=opportunistic_hospitality email) and option #4 here - if the relation values are straight forward, then people will make the jump to learn it. I also suggest a fallback note on the proposal,, such as map the area, amenities, and information as best as possible, and create a new “map note” on the main OSM view to ask for another mapper to complete the relation/mapping.” This way the only thing left to do for a more experienced (but less familiar with the site) mapper is to make the relation. I look around my area every month to see if there are any new anonymous repair tags people have added to the map, so it could get fixed that way. are fixme= notes also acceptable?
