The default configuration that comes with VuFind is designed for MARC21, which uses completely different fields than Unimarc. You will need to reconfigure marc.properties to solve this problem, or else you will need to convert from Unimarc to MARC21 prior to importing. I will send you a Unimarc configuration that was shared with me by another Unimarc user a few years ago -- it may not be completely up to date, but it may serve as a useful starting point.

Subject: [VuFind-General] Help with record structure
I've already managed to install vufind on local enviroment running Ubuntu, and it works fine. If I import teh sample records available everything is fine but I think something is wrong with the export of my ILS.
I atached a sample record, can anyone help to find what is wrong, because I can't import anything to vufind.
My ILS use Unimarc.
Thanks very much for your help.
