Doing it manually would not be worth the effort. On the other hand - running script to detect users (and/or relevant changesets) may be a good idea.curl -s 'http://overpass-api.de/api/interpreter?data="">' | grep user | sort| uniq -c or http://overpass-turbo.eu/?w=%22surface%22%3D%22soil%22+global (and add 'meta' to the output to extract the user/changeset) These have the usual drawback that they only return who last touched the object, not who introduced a particular tag. It gets more complicated to do things exactly right, but this is a good starting point.Getting latest person who edited object is really easy. The history is main problem - is there some API for getting old version for given objects with user/changeset that edited it?At least the main API can give you the old versions of the object in .osm using: http://www.openstreetmap.org/api/0.6/node/$i/$vhttp://www.openstreetmap.org/api/0.6/node/3157502486/history will return the complete list (history) of authors, changesets and dates for a given element.Yes, this would work (some parsing still would be needed). Unfortunately according to http://wiki.openstreetmap.org/wiki/API_usage_policy it is not OK to use API for that purpose. Is OSM.org using that API to display the history on the screen illegal? Is Osmose using it to attribute errors to some user illegal? Yep, I suppose that making oneself a complete list of OSM users is inappropriate. Regarding the needed parsing: use regex (as in perl again): it does wonders! If you need regex drill, install it in some editor like Advanced Find/Replace plugin for gedit. Gorgeous. (there are packages to handle xml more correctly but regex is OK for that kind of predictable, repetitive data.)
