Different person but my prios for export:

1. Versioned export/backup which will be guaranteed to work with current Colanode version

2. ..., well-documented

3. ..., with migrations so it's always future-compatible

4. ..., human-readable

I think integrations with any specific other tools should be ezpz if the fundaments are solid!

For import/insert, I guess some cli API with similar properties would be a nice fit.

(Coincidentally I think the above is also what would facilitate LLMs to do a decent job for anyone trying that)
