Resolving ISBN number conflicts and related meta data download?

So I googled and read a bunch and end up a bit more confused.

How to resolve ISBN number conflicts for books when there are several alternative ones;

(Some in the File Name, Some inside the File metadata, some inside the Ebook Content etc).

I like this as an idea on how it could be implemented. It would be good to also get it Qt 6 compliant (if it's not already).

I would even be willing to donate/pay a nominal fee for anyone who was willing to take this on.

Did this get anywhere?

ISBNs relate to particular sizes of same revision and differ also for different revisions (editions and print runs are not exactly the same thing. The 2019 and 2022 print-runs can have same ISBN if content and format is identical).
So the exact same text can have different ISBNs, and the same title + author can vary a little in content on same size/format book and thus will have a different ISBN. A hardback and paperback and ebook would be three ISBNs. An ebook need not have an iSBN as they are not ordered by physical retail book shops.

Physical Libraries thus use their own barcodes, unique per copy even when the ISBN matches. For ebooks to search for metadata or covers multiple ISBNs are needed. It's of almost no value to fetch an ISBN based only on title and author. An ISBN is really a retail product code for an imaginary country called "Bookland". It's only of use at point of sale in a bookshop, or for a bookshop or library to order/buy-in a particular format/edition currently in print (which means stocked by publisher or wholesale).
