It's probably worth sending them the official french translation of the
CC license we are using, explaining that we are making a world map under
that license, and asking if we can incorporate their data. Also, if we
find errors, and fix them, does that mean we are not "keeping the data
integrity"?

We might need to put their data into a zoned off section of the DB that
we can't edit, and program Mapnik to just incorporate it, like it is
doing with coastlines. We could use a flag to say where it is bad, and
we have made corrections or added more detail, so that Mapnik knows to
render the OSM version of those areas. We could use the same system for
Tiger and other external databases.
