sorry, i should have made that clearer. i would do this as 3 separate items, maybe as a relation (slight overkill, but anyway). the relation would contain 3 nodes, one for the pole, one for the bus stop and one for the post box. thus each can have it's own timetable without any confusion. i would never tag one point (or way) as two separate items, that's asking for trouble, even if the tags don't clash technically this is wrong (not all 3 nodes can easily share the same point and still be editable), but i don't see a huge problem in 2 of them being slightly offset > > > > > a lot of the disputes over tagging are caused by people confusing > > physical items with conceptual ones; if we thought about separating > > them before debating a tagging scheme, things would be a lot clearer > > > > That may be, but I still think in some cases you are going to want multiple > conceptual items attached to a single item - namespacing allows this to be > done without risk of conflicting tags and makes it more obvious how the tags > interact with each item (conceptual or physical). > > The same thing _could_ be done with relations (i.e. you mark up the > physical items with ways and nodes and use relations containing physical > items to represent the conceptial things).
