In my understanding, source:name refers to the source of the *value* being entered in OSM, not the source of the name itself. That is, for name="Wood Road" and source:name=survey, I went there and saw that the name is posted as Wood Road. We wouldn't add source:name="there is a wood nearby". Same for source:ref, source:addr. By the same scheme, source:map=* would specify the source of the value of the map tag is OSM, but that isn't what we're looking to specify - we're looking to specify a property of the object itself (the source of the information of the map object being entered into OSM database). The object is a map, thus potential tags include for example map:size=*, map:braille=*, map:coverage=*, map:resolution=*, or in this case map:source=*. Compare etymology:name=* vs name:etymology=*. --Jarek _______________________________________________ Tagging mailing list Tagging@openstreetmap.org https://lists.openstreetmap.org/listinfo/tagging
