Thanks for sharing looks good. I am sure people will be happy to help you with 
the minute diff file.

Import speed is of no (well little) concern compared to map answering times, I

You can half your database space by dropping <tag 
k="created_by|tiger|ele|source|note"... (and perhaps a few more) username/user 
id is not required either. timestamps could be useful to see how old the data 
is, but I'd not cry if it weren't in the first version either.
