There are many tags with status 'de facto' indicated that do not meet at least some of your criteria:
landuse=meadow landuse=forest natural=wood place=square waterway=drain and there are tags with status 'in use' indicated that at least meet some of the criteria: highway=turning_circle information=guidepost landuse=grass man_made=cutline place=archipelago water=lake waterway=riverbank IMO if those criteria are significant (which i don't doubt as far as they can be objectively determined) it is much more useful to document how far a tag meets these criteria individually than to determine an aggregate score of some sort from them and a categorization based on that. -- Christoph Hormann http://www.imagico.de/ _______________________________________________ Tagging mailing list Tagging@openstreetmap.org https://lists.openstreetmap.org/listinfo/tagging
