Does Koha Support MODS for Import & Export?
Koha currently lets you download bib records converted to various XML-based metadata formats, including MODS, one at a time. It would not be difficult to make a batch MODS exporter, and if you’re OK with the default MODS to MARC21 stylesheet, a MODS import wouldn’t be hard to do either. Although there is a desire to enhance Koha so that it can natively store bibliographic metadata in formats other than MARC, that will be further down the road.
