I use samba and digikam

Yup. Started the Witcher 3 end of last year. Finished Kingdom Come Deliverance. Also play a lot of total war Time 2 and Attila.

What function or class from that library would I use to do this? Or what key words can I use to search and learn more? I’m struggling wrapping my head around it.

Do you happen to have any examples? I’m just not sure how to convert the JSON example into a bulk query since I need to keep the reference and line detail associated to the header. There is no primary key across all 3 sections. It’s generated when I insert into the database.
