AlwaysDoesn't that violatehttps://wiki.openstreetmap.org/wiki/One_feature,_one_OSM_element ? No. The route traverses the way, it's not the way.Okay. But surely this doesn't mean that every named footway or path should be part of a route relation. The bike trail that brad linked to, https://www.openstreetmap.org/relation/6632400 -- I've never been there but I don't offhand see any reason to call it a route. (Brad has been there, I assume, because it looks like he updated it 2 days ago.) There's no information in the relation tags that isn't also on the way itself. Is there any benefit to creating a route relation in cases like this? Better handling of future way splits, consistency.
I can see the advantage of using a route relation as a somewhat future-proof persistent identity -- a relation URL that will show the whole trail even if the way is split to add a bridge, specify surface, etc. At the same time, though, it feels like a bit of a stretch to declare any named trail of any length as a route, and I'm not inclined to tack route relations overtop of the single-segment trails I'm working on (unless they're long or part of a network.) As I mentioned, I suspect that a large force behind this is mappers wishing certain trails to be processed or rendered differently by various third-party software. Regardless, if there really is burgeoning enthusiasm for this technique, one of you single-segment route advocates might consider explaining it on the wiki. The current language uses a lot of plurals... "may go along roads or trails or combinations of these" "consist of paths taken repeatedly" "Add all different ways of the foot/hiking route to this relation. The order of the ways matters." ... which leaves mappers like me & Brad scratching our heads when we encounter one of these singleton routes. J
