[OSM-talk] Craigslist OpenStreetMap Rendering Issue

[Marc Gemis]

just a few thoughts:

What is the value of a 1 time mechanical edit cleanup ? From the moment you
ran your script, new data can arrive in the OSM with the wrong values.
Will you run your script daily ? What if a data consumer obtains the data
between 2 runs of your script ?

Wouldn't it be better to properly inform the data consumer about the
existence of some "fix" scripts that can be run after obtaining the data
from OSM ?

Of course one could imaging an OSM setup where those mechanical edits would
run automatically after each submission, but that is out of the question I
think. Part of that work could be (or is) done by the validators in the
editors.
