It would also be good to have a CDI data import demo, once we have all the kinks worked out

Maybe create future templates using #123, they should be a lot leaner

(seeing how many id issues are being found by the validator now , maybe the templates going forward should discourage the legacy way of doing imports?)

[adriansteffan]

The new command to start both idless and legacy imports provides a commented template and takes care of the overall script structure (tailored to the new v2024 schema). I would argue that any further functionality that targets specific data sources (icoder etc.) should live in central helper functions rather than duplicated templates. -> Carefully closing this for now.
