I don't think that's fair. We do have the general (and generally misinterpreted) rule of "don't tag for the renderer", but there's also the assumption "don't make every single client's life needlessly hard". In this case, anyone building a worldwide render or router from OSM data will have to build in an obscure chunk of UK-specific logic - roughly speaking, where ref=~/^[C-Z]+\d+/i, don't show it - or their renderer or router will show confusing information. It doesn't degrade gracefully. Yes, granted, there are one or two other cases where international tagging differences don't degrade gracefully (bikes being forbidden on highway=trunk is the one that springs to mind), but we should seek to avoid creating more. > [...] > Otherwise we're likely to continue with an inconsistent mixture of > ref, admin_ref, official_ref, local_ref and probably others too. Yep. local_ref doesn't really explain what this putative tag would do (these refs do happen to be set by local authorities, but that's not the point we're addressing). Taginfo reports that admin_ref has significantly more uses than official_ref, admin:ref and official:ref, and it's consistent with the established _ref principle. I'd therefore suggest we go with admin_ref, but am open to arguments! cheers Richard -- View this message in context: http://gis.19327.n5.nabble.com/Complaining-about-refs-on-roads-again-tp5759139p5759241.html Sent from the Great Britain mailing list archive at Nabble.com. _______________________________________________ Talk-GB mailing list [email protected] http://lists.openstreetmap.org/listinfo/talk-gb
