I am irrationally annoyed that this isn't https://ref.gs1.org/17/382834828282/21/28312384021

I'm also a bit irrationally annoyed by the example. You seem like someone who could explain why a barcode URI isn't defined as a proper URN?

Because the consumer has to be able to trivially scan it with their smartphone and get useful information out of it. In reality, that means it has to be a valid URL you can visit with a web browser, as forcing literally everyone to install a proprietary URN-handling app is a dealbreaker.

The whole point of it is that you can just say "scan the barcode with your smartphone to find out if your product is part of this recall".

URN that can be copied and put in any national recall website seems better to me. I don't understand who I am supposed to trust to keep domains with the right content on them instead of porn sites. Seems very high faith for clown town.

404?

A standard with an expiration date?

And that is not a correct URL according to the standard, either..
