[OSM-talk] How to deal with data duplication in bulk upload

[Maciek Kaliszewski]

Hi

There is a project http://wiki.openstreetmap.org/index.php/UMP2OSM which 
allows to import some (currently only streets ) from UMP.
But what if data already exists .How it was dealt in other bulk uploads 
,say tiger .  I'm worrying especially about Warsaw.

It would be nice if josm had feature to merge ways. I know it isn't easy 
but imagine you select two ways click merge and in result you have one way.
