@eickot@mastodon.social @davidrevoy@framapiaf.org TBH, I wasn't aware metadata were supported in a CBZ file, provided that it's just a Zip file 😅
That's where OPDS is an interesting choice: you can separately provide info about the books.
I will look into the repo you provided to see how I can embed info inside the files
And about the French lang, it's just for my personal use, and you just have to fork the repo and edit the gitlab-ci.yml to generate an OPDS Catalog that will fit your needs (everything you need to know are in the Readme and in the embedded help of the python scripts)
