I'm looking for a library management software for my organization, so i've found koha. Interesting... ;-))) Some question: 1) there's just a translation in Italian?! Can i contribute this?! 2) i want to use koha with postgres, but i need assurance that work with potgres. I've had experience with other software written for mysql that in theory work with pgsql but in practice all sources have to be rewritten. ;( 3) In any case need to be rewritten the schema. Please, don't distribute the schema in mysql dump format, is not portable and are full of (nonstandard) SQL instruction. Someone have just rewritten the schema for postgres?! Basically have to be rewritten the KEY instances (to CREATE INDEX) and the auto_increment (to serial). Again: PG support real referential integrity (FOREIGN KEY). There's somewhere a E/R schema that explain referential integrity, or can i add referential integrity (if someone exlain me the schema?!). 4) I'm new to library related problem, but seems that the MARC format is a standard in this field. Someone know if this also rule for european country?! Before starting a big google session, if someone have some pointers... Thanks. -- dott.
