Yes, unfortunately instead of discussing the issue there was repeated wiki fiddling on this issue. I tried to dig into this and am presenting the results here: agricultural was introduced 25 Dec. 2007, but without further definition: http://wiki.openstreetmap.org/w/index.php?title=Key%3Aaccess&action=historysubmit&diff=66244&oldid=14009 on 4 Feb. 2009 there was a definition added: * {{Tag|access|agricultural}} ''Only for agricultural traffic.'' http://wiki.openstreetmap.org/w/index.php?title=Key:access&diff=next&oldid=218932 (this might have been intended as a use condition, because otherwise it would have been "agricultural vehicle", but actually the wiki was still not very clear, because in the following time it listed use classes (hazmat, emergency, hov) together with vehicle classes (motor_vehicle, hgv). This is also reflected by the diagram that was added on 23 Feb. 2009: http://wiki.openstreetmap.org/w/index.php?title=Key:access&diff=prev&oldid=231676 and amended on 11 March 2009: http://wiki.openstreetmap.org/w/images/e/e9/Access_modes.png on 20 Aug 2009 there was a contradiction introduced, agricultural was still defined as agricultural traffic but the same time lower in the page there was added this (still there was no distinction between use cases (hazmat, emergency) and vehicle types): agricultural=* (agricultural motor vehicles, e.g. tractors, that have additional restrictions, e.g. a 25km/h speed limit). The diagram was replaced. 5 days later this was relativated by separating "by use" and vehicle classes, keeping the class definition for agricultural in parenthesis though: http://wiki.openstreetmap.org/w/index.php?title=Key:access&diff=prev&oldid=327300 This situation was kept until 5 Jan 2012, when "agricultural" was moved from "by use" to "double tracked vehicles". http://wiki.openstreetmap.org/w/index.php?title=Key%3Aaccess&action=historysubmit&diff=720329&oldid=720323 Which is where we are now. The beginning of the page still states that agricultural is a tag for agricultural traffic. How can we resolve this? It seems obvious that we need either 2 tags for agricultural (according to the legislation, either a vehicle class or a use case is intended), or we accept that the same tag has different meanings in different legislations/countries. Personally I am in favour of an additional tag. We could also have 2 new tags: "agricultural_use" and "agricultural_vehicle" to make it unambiguous, and to deprecate the unclear agricultural. What do you think? cheers, Martin _______________________________________________ Tagging mailing list [email protected] http://lists.openstreetmap.org/listinfo/tagging
