I like to put these things into perspective. This is the hierarchy:

- Spatial
- Map

I think Spatial in Kexi can be easily done using Spatialite. It is

- Sqlite3 + the geom (geometry column added in Sqlite3 file).

Once Kexi can accept (write and read) raw Sqlite3 files (i.e. .db and
.sqlite), it just adding the geometry column (e.g. geom or geometry)
in the table.

GEOS, Proj4 are dependent libraries for Spatialite.

Jaroslaw, I think can we probably propose a GSOC for SQLite3 for Kexi.
It seems that since 2007 Kexi users need read and write access for
SQLite3 in Kexi.

Any comments?
