I dunno what is "simple flat file DB", and don't really like the idea of inventing our own DB (there must be enough DB's around already :-) ), so if we reuse existing ones there are, at least, * HSQLDB option that David already mentioned, * ODF (the ISO document format used by OpenOffice/KOffice) which is basically XML so is user-editable. * XML itself * JSON - also user-editable These options are all supported by DataNucleus -- Andy (DataNucleus - http://www.datanucleus.org)
