I’ve seen my nearby playgrounds use everything from leisure=water_park areas to amenity=fountain areas to leisure=playground areas with point fountains inside them. The iD editor has a nice suggestion and icon for a simple playground=splash_pad (with no other tags), but then those areas don’t appear on the default openstreetmap.com viewer.
No one has complained yet. On practical level, leisure=playground is what makes it render, then playground=splash_pad refines (specifies what kind of) playground.
Nice, that makes sense semantically and seems like the right answer. I’m still new to OSM and trying to find my way here so I still have some questions —
Part of my confusion stemmed from the abandoned proposal. I guess that abandoned really doesn’t necessarily mean anything at all about the status quo practice; it’s neither rejected nor accepted.
But another part came from iD editor finding a feature called “Splash Pad” and happily labeling a new area as such without the leisure tag. Could it be changed to have both tags? Where would one define/change that?
And then the third part is how it ended up rendering. It seems your suggested triplet of tags looks exactly like all other playgrounds with the default OSM rendering. Could it show something water-y or splashy instead? How’s that defined/changed?
Unfortunately, the standard map doesn’t render everything one would like. But anyway, from the wiki page on playground
The key playground=* describes devices and installations on a playground. It should be tagged to separate objects within the area of a playground leisure=playground.
If a play equipment takes up the whole space of the playground’s area leisure=playground, then tag it on the playground area itself with this key.
