[OSM-talk] need advice for clever query or script

[Richard Z.]

Hi,

trying to clean up bridge=swing as far as possible. There was at least
user in the past who used the combination systematically wrong, so I want
to split the result by user who introduced the bridge=swing.

To make things complicated - a few days ago one contributor did a well 
meant effort to convert all
  bridge=swing -> bridge=movable+bridge:movable=swing
and reverted that edit because there were too many errors in it. Hence
doing a naive search for user doesn't work.

So I want to :
 * find all bridge=swing
 * split results by the first contributor who added bridge=swing
   to the way
 * get the results into JOSM for examination and editing

Tia for any hints,
Richard
