Agreed, the 'not' would only be used when one is sure of the right answer based on some clear evidence and where there is a reasonably chance that someone might change it to an incorrect value. Possibly one could stretch the syntax a little more and put structure into the note tag as well. For example: name=Rosehill Road not:name=Rose Hill Road not:name:note=There are streetsigns on 'Rosehill Road' show different versions at each end, however I checked with the council and they say that the formal title is indeed Rosehill Road however they do not intend to change the other sign for the time being. Or.... Ref=A999 not:ref=998 not:ref:note=This used to be called the A998 but is now the A999 - some maps and signs still show A998 but the designation changed on the xx/xx/2010 Incidentally, with reference to Rosehill Road in Ipswich the signs do indeed vary at each end of the street - I haven't checked with the council though. I believe the OS choose the one with least spaces unless they get other guidance. Here is another example where OS Streetview and Google/TeleAtlas are not the same as the sign and I have used the proposed 'not:name:note' format for the note field. In this case however OS Locator hasn't complained so I think it is an example of where OS Streetview and OS Locator are not telling the same story. http://www.openstreetmap.org/browse/way/4211155 Regards, Peter > > Cheers, > Andy _______________________________________________ Talk-GB mailing list [email protected] http://lists.openstreetmap.org/listinfo/talk-gb
