My last comment was meant to be tongue in cheek, although if we were starting from scratch it would perhaps make a bit more sense if the tagging was a bit more object oriented, such as perhaps Highway=residential Highway:access:car=destination Highway:access:psv=no Highway:maxspeed=30 Highway:surface=asphalt So, basically you'd have object:object property:property of object property:etc=value At present you might have a situation where you want to apply a number of tags to a way and isn't always clear which tags apply in combination. I'm tired though so can’t think of an example offhand. But we aren't starting from scratch... As a relative newbie, I read the wiki (or the bits I tracked down) to learn how to map. I read the introduction to JOSM, which got me uploading traces, downloading areas, adding nodes and ways and tagging them. JOSM is fairly good at offering "valid" Map Features, so once Maplint did start working for me, what it highlighted (apart from parking aisles) were generally things I needed to look at. But when people map things, surely, usually, they want to see the result of their efforts. Presumably if they use things documented in Map Features then what they map will show on at least one of the different layers. And if they don't then it won't. I think there was a recent discussion on one of these email lists about a graveyard that wasn't rendering, and if I remember correctly what is documented in Map Features isn’t what actually renders (something about choosing between amenity and landuse). While I've read many times that we aren't necessarily mapping for renderers, the more consistent the tagging the more likely the renderers will render any given feature and the more useful the data will similarly be in any other utilisation. What I would like to do if I get time ever (unlikely) is to try and make a page as I think Germany have suggesting how various roadsigns equate to tags. This would highlight any obvious current limitations, and hopefully then any even more complicated combinations of restrictions (such as taxis, buses and bicycles only from 10am to 4pm) could also be added. We could get people submitting signs they want help with and use people's experiences with mapping to try and come to a majority decision on how they'd do it. One sign I do wonder about is "No Through Road". I can't see this is ever worth adding unless we are tagging the street signs; the map itself, if complete for an area, should make it clear whether you can get through or not. And again this particular sign sometimes only applies to motor vehicles and not cyclists.
