We are currently building our Omeka S site and want to make sure that, in the event that outside circumstances force us to switch platforms, we can export our data in a way that easily preserves the relationships between items, item sets, etc. I know the CSV Export module exists, but are there other functions within Omeka S that would work to export to a relational database format?
We are currently running Omeka S 3.0.1 with the CSV Import, Custom Vocab, Mapping, Metadata Browse and Numeric Data Type modules.
