OK, so spelling corrections could be viewed as not removing the taint, because we can't tell if the agreer making the change used a odbl/CT-compatible source for the change or not.
Thinking about it, other edits done by "bots" to normalise the tagging into a "standard" (e.g. changing something like leisure=swimming_pool into sport=swimming [that's a made-up example off the top of my head!]), could also be viewed as not removing the taint, because we also can't tell if the agreer used an odbl/CT-compatible source or not. However, we could add something to the taint checking that would ignore the taint of specific tags if changes of specific tag values from one "official" value to another "official" value had been made. It seems that it is quite difficult to imagine all of the different scenarios though, so it sounds as if such tests would need to be very specific (e.g. 'A change of the highway tag from one official value to another official value, removes the taint from that tag). There are probably other specific tags, for which we could define similar specific changes which would remove the tag. Maybe for the name tag, the taint checking could check to see if the new value is just a spelling variation or a completely different value (using some kind of fuzzy string matching?) - with a completely different value resulting in the taint being removed from that tag? It's obviously a bit more complicated than it first appears, but I think that there must be some additions that could be made to the taint checking to remove the taint in specific, well-defined situations, which would hopefully reduce the amount of supposedly-tainted data a bit (how much. I'm not sure). -- View this message in context: http://gis.19327.n5.nabble.com/OSM-legal-talk-Is-an-object-created-by-a-non-agreer-always-tainted-even-if-all-info-has-been-deleted-tp5450719p5452068.html Sent from the Legal Talk mailing list archive at Nabble.com. _______________________________________________ legal-talk mailing list legal-talk@openstreetmap.org http://lists.openstreetmap.org/listinfo/legal-talk
