Disclaimer: I am not a cataloger, the following advice may rest on inaccurate assumptions.

Looking around PyPi, maybe it could be done by these two libraries together?

    Hi All,
    
    I was looking at this website: https://www.loc.gov/standards/mods/mods-mapping.html#mapping
    
    Is there a python library (or even just a JSON file) that transforms MARC to MODS?
