Making GS1 IDs part of the Web: every barcode can be a gateway to multiple sources of info. Formerly at W3C. Radios 3 & 4 and LBC listener, bibliophile.
@Edent Interesting (to me) that you used upper case for the scheme and domain name, thus using the most efficient way possible to encode the URL. I'd be very interested if you hear of anyone who's phone tries to open an app rather than just the browser. Seems to happen on Nokia G-series phones.
In the image below, there are two QR Codes. Both contain the same URL. However, the one on the left has the scheme written in upper case (HTTPS) and the other has it in lower case (https).
Both should work in exactly the same way and redirect to the GS1 homepage. However, I hear that some phones, especially older Android phones, try to launch an app, rather than just open the URL in the browser. Can you check with your phone please?
AIUI, the folks behind JSON schema have resisted the idea of it becoming a formal standard anywhere. I'm not in the community so I don't know whether that's fully true or what the background might be, even so, it does seem that the first steps along the path to an RFC have been taken https://datatracker.ietf.org/doc/html/draft-dusseault-json-schema
JSON Schema
JSON Schema defines the media type "application/schema+json", a JSON- based format for describing the structure of JSON data. JSON Schema asserts what a JSON document must look like, ways to extract information from it, and how to interact with it. The "application/ schema-instance+json" media type provides additional feature-rich integration with "application/schema+json" beyond what can be offered for "application/json" documents.
Not a trial, not a pilot. This is a real product on sale at my local Tesco with a future-looking barcode (QR). 12 years from concept to real life. I have been part of tjis journey for the last 8.5 of those years. #GS1 #DigitalLink
I received an email yesterday, 25th Feb, that began: "Hi Phil, Happy New Year". 25th February!
@torgo I very much feel your pain, Dan. Heck, I even blogged about it https://philarcher.org/diary/2025/passport/

That's how you do it...
Working through some old issues for the UN Transparency Protocol spec and saw a comment that made me think "yeah, that's right!" - and then saw that it was me who wrote it months ago...
I really don't like the idea of URLs that include the service and the "secure" data that service is meant to process. I want to choose the service I use to verify your credential if I'm going to trust it.
