Hi ralfhauser,

please write changeset comments that can make other people understand what you edited, ".." is no help. You could write at least "edit drinking water", see: https://wiki.openstreetmap.org/wiki/Good_changeset_comments

also noticed that wikimedia=* commons as a tag to be followed as wiki, so it should be wikimedia_commons=Category:Brunnen Obere Wiltisgasse Küsnacht
 instead of wikimedia_commons=https://commons.wikimedia.org/wiki/Category:Brunnen_Obere_Wiltisgasse_K%C3%BCsnacht

good mapping
