Fix that at the presentation layer (PDFs and Word files etc support links) not the data one.
Let me know when you figure out how to make a printed scientific journal clickable.
Scientific journals should not rely on ephemeral data on the internet. It doesn't even matter how long the url is.
Just buy any scientific book and try to navigate to it's own errata they link in the book. It's always dead.
Take a photo on your phone, OS recognises the link in the image, makes it clickable, done. Or, use a QR code instead

This is the answer; turns out that non-transformed links are the most generic data format, without any "compression" - QR codes or a third-party-intermediary - needed.
