you seem to imply that there is just one way to look at the world. A=B with subtypes of B, but a wall engraving is something completely different (artwork) than a hedge or a ruin of an ancient religious site, all of which can come in the form of a maze. E.g. we are _not_ tagging man_made=metal_plate and then distinguish metal_plate=memorial metal_plate=sluice_gate metal_plate=roof metal_plate=hole_cover etc. Instead we use building=roof for all kinds of roofs and historic=memorial for some kinds of memorials, and don't care whether they are made of a metal plate or not. There are infinite ways to structure / classify / interpret the world, which are "main classes" and which are "sub classes" is something that evolves within our open tagging system. There is no "usual OSM practise" in a way it would determine how to classify mazes. > My preference is for one tag xxxx=maze .. if a distinction is to be made > between them then use a sub tag.. but there does not look to be enough of > them for that to be worthwhile? > > So the choice for tags so far is > > attraction=maze ... looks too restrictive if restrained to only amusement > parks. > historic=maze ..looks too restrictive as new mazes would be excluded. > So I'd exclude the above two. > > amenity=maze > leisure=maze > tourism=maze > > I'd be tossing a coin to chose between the three. > to describe what kind of object? cheers, Martin
