Presentation held at the FIAF CDC Workshop “So Much More Than Non-Film: Cataloguing Film-Related Materials” in Stockholm 25.05.2023. Presentation focused on the ongoing migration work from the Mavis system to Axiell Collections at the National Library of Norway. Emphasis on how the LRM/EN15907 models can be applied in a generic manner for different types of materials. Some thoughts on “marrying” catalog models with traditional archiving models.
