I think this is a good idea. Both in the sense of establishing a distinct tagging for it that does not engross qanats with other types of underground waterways and in the sense of using a non-English and non-European term where the most descriptive and clear term comes from a non-European language. We have other cases of such tags in OSM but still in a proposal process which is dominantly discussed in English this is rare and kind of a litmus test for how culturally diverse tagging in OSM can be and if the cultural geography of non-European regions can be mapped in the classifications used locally just as we are used to doing it in Europe and North America.
Most existing uses of man_made=qanat by the way are in combination with waterway=canal. -- Christoph Hormann http://www.imagico.de/ _______________________________________________ Tagging mailing list Tagging@openstreetmap.org https://lists.openstreetmap.org/listinfo/tagging
