Hello, Jonathan & me took 3 hours working on database design. We've created a wiki page with all the mistakes we've found. The page is http://wiki.koha-community.org/wiki/DB_schema_bugs you're welcomed to read it, add anything that could have been forgotten, or discuss what must be discussed. There are 2 kinds of entries in this page: * italic lines => we've found the problem, we don't have a solution, feel free to add your voice to the discussion tab of the wiki (http://wiki.koha-community.org/wiki/Talk:DB_schema_bugs, I already have filled it to ease the talk) * non italic lines => unless we made a mistake, those don't need to de discussed, they are obvious mistakes we will fix ASAP (which does not mean soon ;-) ) Enter the game ! -- Paul POULAIN http://www.biblibre.com Expert en Logiciels Libres pour l'info-doc Tel : (33) 4 91 81 35 08
