Not quite true - API map calls return normal OSM files with the visible attribute set. > Objects in full history OSM files contain a "visible" attribute, and these > files may contain different versions of the same object, with at most one > having visible=true. Again, not quite true - full history files returned by the api history calls contain different versions of the same object, where many versions can be shown with the visible=true attribute. Perhaps it could be summarised as "There are many different pieces of software generating both normal and full-history OSM files, and simple and replication diffs, and the visible attribute may or may not appear in any of them." :-) Cheers, Andy _______________________________________________ dev mailing list [email protected] http://lists.openstreetmap.org/listinfo/dev
