The Koha API allows for existing records to be replaced/ overlaid wholesale with data provided. It would be great to have the option of updating records as well, i.e., changing only data/ fields that are included in a source file while preserving all data/ fields not in the source file. This would require a means of identifying fields that are protected from overlay on import.
