[1] http://wiki.openstreetmap.org/wiki/Tag:access%3Ddesignated [2] http://wiki.openstreetmap.org/wiki/Tag:access%3Dofficial to me [2] seems unambigous and clear. The definition has never changed and there is only one author, so I don't think that there is need for changes on this page. The only problem I think could be there is what is said about Germany ("compulsory") I suspect it is not completely true the way it is written in [2] (I am only aware about bicycle tracks, bridleways and sidewalks being compulsory _under certain circumstances_, not in all cases). In [1] the first paragraph is a link to a UK-specific page (usually country specific stuff is not in the beginning of the pages) and there is still a lot of UK-examples on the general page [1] as well. Definitions and rules are set in [1] as if they would make sense in a general way, but actually they mostly deal with exceptions, e.g. this: "To indicate an exclusive access use access=official, or just use access=no in addition to a mode-specific key (foot=designated, bicycle=designated, etc.)" The first does not make sense on roads or paths IMHO, only on footway, cycleway and bridleway (highways designed for a specific means of transport). >> Strange tagging.

According to taginfo 10% of these 21000 aren't even highways. I don't think this is a particularly lucky choice of tagging, as a meaning only emerges together with other tags (mostly the highway-class), but in the case of a mode-specific highway-class it does make sense. On general roads it doesn't. This also becomes clear from the first sentence: "This tag indicates that a route has been specially designated (typically by a government) for use by a particular mode (or modes) of transport."[1] You could still express the same with foot=designated (for instance) which I'd prefer over highway=footway, access=designated. cheers, Martin _______________________________________________ Tagging mailing list Tagging@openstreetmap.org http://lists.openstreetmap.org/listinfo/tagging
