Hi everybody, In the 1.3.3 version, the UNIMARC/french parameters table are working well, they have been builded by a librarian with my help. the MARC21/english tables are NOT in a safe state. fields choosen are stupid, and some causes pain in the software. I call here for someone with a good MARC21 practicte to complete those MARC21 tables to fit a "standard" MARC management. Maybe Ambrose ? Or NPL ? It's quite simple to do : modify parameters with the GUI, and when you get something nice, dump the tables marc_tag_structure and marc_subfields_structure in a .sql file, then send it to me, or put it on cvs, in misc/marc_datas/marc21_en/structure_def.sql ! I will add as soon as possible a tool in the admin screen to check some mandatory things, to get sure that the parameters are consistent (as described in http://www.saas.nsw.edu.au/wiki/index.php?page=UserDoc ) -- Paul POULAIN Consultant indépendant en logiciels libres responsable francophone de koha (SIGB libre http://www.koha-fr.org)
