If the KBART file imported contains an optional column not defined by the format (like "bestpnn" column present in KBART files imported from https://bacon.abes.fr/ ), this information is lost by Koha, while it may be useful. We could store it in that way : - give the ability to create additional custom fields for ERM titles (like agreements or packages) - give the ability to map an optional KBART column with the custom field
I like the idea of using additional fields for this with a mapping on the name of the column. GOKb also uses additional fields in their KBART exports and storing that information could be very useful.
