Interesting. I want to try to this for my Magic: The Gathering cards since it is a pain manually inputting cards into my collection when buying the in bulk.
You could have an LLM analyze pictures of each card to extract the attributes you want, eg. to json, then ask it to write code that will input it to your library.
The intermediate step of json gives a chance to check and clean the data before upload.
May be worthwhile to invest in an Epson FastFoto scanner to help speed up digitization.
