zif.sedna provides python access to the very cool XML database, Sedna, available at http://modis.ispras.ru/sedna/, under Apache 2.0 license.
It's not about kool-aid or sit-ups. It's another option for storing, modifying, and retrieving hierarchical data. zif.sedna is available from the Python Package Index. zif.sedna provides a dbapi-like interface (connections and cursors). zif.sedna provides a database adapter for Zope(3) and now has preliminary instructions for use with pylons. Sedna is a product of the Sedna Team at the Institute for System Programming, Russian Academy of Sciences . zif.sedna is just an adapter package. -Jim Washington -- http://mail.python.org/mailman/listinfo/python-list
