ODF Documents

DataNucleus supports persisting objects to Open Document Format (ODF) documents (using the datanucleus-odf plugin). Such documents can then be used in applications like OpenOffice and KOffice. It makes use of the ODF Toolkit project. Support for ODF is in its early stages and will be enhanced in future releases. If you wish to help out in this effort either by contributing or by sponsoring particular functionality please contact us via the DataNucleus Forum.
