The problem is that railway=tram_stop is used to mean a number of different things, which have different geo-locations when you start mapping in more detail. You are emphasising one particular meaning (the stop area centroid), and other people emphasise another meaning (an indicator of the boarding location). We can't know which is dominant. To ensure basic compatibility, I suggest all schemes should use nodes tagged railway=tram_stop, and make them ordered members of the route relation with role=stop (or maybe forward_stop/backward_stop). I don't think we need to be prescriptive about where those nodes are placed, just tell people there are two basic options (on track or either side of the track). I think the "simplified" scheme probably _recommends_ these nodes should in due course be beside the track, and possibly on platforms, and that something else (railway=tram_station) should go on the centroid as a courtesy tag. Teddy - you are perfectly entitled to use a more-elaborate scheme, and perhaps lots of other people will use it. Tagwatch: http://tagwatch.stoecker.eu/Europe/En/relationstats_route.html has about 350,000 nodes as members of route relations, and 12,000 (ie 3%) with role=platform Richard _______________________________________________ Talk-transit mailing list [email protected] http://lists.openstreetmap.org/listinfo/talk-transit
