That is great. I did some work in this area by working out the unified_stoparea proposal some months ago. I am really happy there finally seems to be some progress in this area. :) Here are some notes I have after reading (the German version of) your wiki page. I'm writing this before I read responses to this thread, to not get confused. I hope this won't be obsoleted by what others wrote... - the "usage" tag (and similar tags) Here I would prefer to use hierarchical tagging, so instead of railway=rail; usage=branch I would rather write railway=rail:branch - ref/name tags If you intend this to be filled with information like ref="Line" 10 or name="Main station - zoo" I would rather see this information with the appropriate route-relations. Things like name="Ringleis" which name the actual rail corpus and not the train traveling upon it, are fine with me. - "Stadtschnellbahnen" (German) It confuses me, that these only consist of subway and monorail. I think the term may cause some confusion. I do not think it is necessary to combine these two and form a group for them. -separate geometry with tram I disagree that this is a good idea. Most attributes belong to both (the road and the tracks within the road). Together they form one entity. Attributes that do not belong to both should use hierarchical tagging scheme, e.g.: railway=tram:disused railway:gauge=100 railway:operator=railcompany highway:operator=citymanagement -concerning the tagging of transport stops. Please have a look at my proposal regarding this: http://wiki.openstreetmap.org/wiki/Proposed_features/unified_stoparea it is very similar to what you propose and is already used by quite some mappers throughout Europe. Please try to build upon it, as you are basically defining something very similar with new tag names. I am not sure if it would be necessary or wise to have everything under the "public_transport" name space as you propose All in all, I am very happy with this scheme, foremost that someone cares about this. :) I am not sure if the scheme is not to complicated for the casual not-so-concerned mapper. That is why I was trying to change as little as possible with my proposal and allow a wide range of detail levels. The irony is, that I personally rather prefer a complex and complete model to the change-as-little-as-possible approach I finally proposed (I'm German after all ;-) I am eager to see, how your proposal is received by the crowd!
