[OSM-dev] CloudMade OSM download problems

[Brett Henderson]

Importing into an OSM instance is always problematic due to the foreign 
key relationships.  They're a good idea in the central database, but 
difficult to satisfy when working offline with extracts and changesets.

OPTION 1
If you're just trying to import a one off extract into the database you 
can use osmosis to fix the referential integrity problems.
osmosis --rx myfile.osm.gz --bbox clipIncompleteEntities=true --wx 
myfixedfile.osm.gz

That should modify ways to only refer to nodes that actually exist.  No 
coordinates have been passed to the bbox task so it will select the 
entire planet (or in this case, the entire input file).  Note that 
modified ways will no longer match the main API ways exactly so they 
should never be uploaded back to the main database.

OPTION 2
If you wish to apply changesets to your database to keep it up to date 
you'll probably need to drop the problematic foreign key relationships.
