Oxomoa has been criticized as unnecessarily complicated, and you seem not to have addresses this issue. What is now proposed is in my opinion worse that what was before, exactly because it does not address oxomoa's issues. The proposed schema is more complicated, i.e. instead of one point for a bus stop, three (!) are proposed: one for the place where the bus stops, and two platforms, if they exist. Moreover, the unnecessary in 99% of cases practice of using two relations for each line is kept, two relations (one in each direction), plus there's a mother relation, the so-called "route master". A few important issues arise: * First of all, *Potlatch** does not allow the creation of nested relations*. Potlatch, when I last looked at statistics, was responsible for 1/3 of all edits. How do you plan to address this issue? * Secondly, the creation of such relations is neither easy, nor quick. It may discourage new mappers as *the learning curve would be much more difficult*. And it may be perceived as an unnecessary and discouraging. Not the way to go if we want to increase the quality of the map, which has to be done by humans. * Thirdly, Please again *elaborate on the efficiency* of such a solution, because it seems that the small gain in quality is offset by the huge loss in time necessary to achieve this. Also, maintaining lines in *three *relations will be hell: any change of the line will require at least *double* work. Is there really a good reason for the double work? There have been other proposals how to deal with lines that have different trace in each direction, and those were easier than one relation in each direction (disclosure: one proposal was mine) As for the examples, all those below seem to be coming from you: http://www.openstreetmap.org/browse/relation/1342798/history http://www.openstreetmap.org/browse/relation/1244886/history http://www.openstreetmap.org/browse/relation/1281532/history Is there anybody else using it? I'd like to see more examples out of Germany or Switzerland, bitte. -- Best regards, mit freundlichen Grüssen, meilleurs sentiments, Pozdrowienia, Michał Borsuk
