So I would like to use DB4O (An object oriented DB that can be embedded).

The DataSet dataSet that was returned from the parser can simply be added to
DB4O by the following call assuming that the db object is already
initialized.

db.set(dataSet);
db.commit();

Easy huh?  So are you suggesting that JOSM cannot do what I require?  If
not, then the libosm would have parsers that are similar to JOSM?

Thanks
