Hi, I'm here again. As I wrote in a previous thead ( https://lists.katipo.co.nz/public/koha/2024-August/060888.html) I realized that I have a corrupt default MARC bibliographic framework I don't know why, I don't know since when. I didn't bothered because frameworks we currently use are almost correct. Now I need to add a items subtag (995.s in unimarc) that is missing and I need a correct default framework. (and I hope that this could help me to fix the previous thread i mentioned before) I managed to export a csv file for a correct default framework from a temporary new installation. But when I try to import the .csv over the default tag (and subtag) structure apparently nothing happens. Looking into the database (tables "marc_tag_structure" and "marc_subfield_strucure") I see that there are a number of records with the field frameworkcode valorized as "defa" that apparently contain the correct default structure I intended to import. Now I wonder what can happen if I sobstitute records with empty frameworkcode with those with "defa" as frameworkcode (i.e. cut records with empty frameworkcode and empty frameworkcode field where it is equal to "defa"). Or maybe somebody has an idea on how reset the default MARC bibliographic framework In any case thanks a lot tommaso È strettamente vietata qualsiasi forma di utilizzo, riproduzione o diffusione non autorizzata del contenuto di questo messaggio o di parte di esso.
