it's hard to explain without an example. from my personal experience with the ongoing cleaning of toilets:wheelchair et wheelchair, there were 3 reasons : - a bug in an editor that incorrectly filled in with a "default" as value when the user did not fill in a value. - an (old) import (without a doc or missing link to the doc) that assigned default values (also I guess it happened when he didn't have any data) - when an editor proposes a few keys, somes mappers do not know what to fill in and put "unknown" thinking that it is mandatory to fill in all the fields to pass validate. This obviously has no interest in any of the 3 situations (the bug of the first one has been fixed, the 2nd will soon be cleanup, the 3rd one is more complicated because it is necessary to "train" new users and/or improve the ergonomics of editors.... this can be seen for example with the access key where you can even see "no ski" on roads of a city a thousand km away from the ski resorts. if you see a recent case, it is interesting to find the cause to inform the mapper and/or improve the ergonomics of the editor used.
