I am looking for an alternative to import annotations within the Calibre annotation system itself. Is there anything doing that at this point?
Or do you know if there is work done on the topic?

I'm not opposed to programming some stuff by myself. That being said, I don't know where to start. Is there an API to add annotations, or should I directly edit the

metadata.opf

to add the annotations there? I'd have to compute the EPUB CFI for each highlights. Is there an API to search through the book, or should I crack open the EPUB? How? Any lead to compute the CFI then?

All in all, if you have some pointers, thank you.
