It must be separate enough to: * not allow reusing objects from "main" database * to have different description on what is allowed in it (for example allowing objects borders of which cannot be precisely defined etc.) In general it is an advantage that the main database does not have layers. In "standard GIS" layers separate data thus we can get bus stops in the lake or on the building, road going into the lake etc. In OSM it is much easier to spot such problems (and fix them) because it is only one layer. -- Tomas _______________________________________________ Tagging mailing list Tagging@openstreetmap.org https://lists.openstreetmap.org/listinfo/tagging
