Re: AW: The German Government slams JSON-LD

  1.
I gave you relevant IA on PID
  2.
on WRAC see https://eur-lex.europa.eu/legal-content/EN/TXT/?uri=OJ:L_202500848

Recommend to have look in IA first before we criticize

He Steffen,

I did not find anything.  I believe this is OK since there is no consensus on just about anything with respect to identity.  In Sweden you cannot do anything without a "personnummer" while in France, this is considered against the constitution.

In https://github.com/eu-digital-identity-wallet/eudi-doc-standards-and-technical-specifications/blob/main/docs/technical-specifications/ts12-electronic-payments-SCA-implementation-with-wallet.md#23-sca-attestation-metadata I found this little gem:

             "schema": "urn:eudi:sca:payment:1",
             "claims": [
                 {
                     "path": [ "payload", "transaction_id"],
                     "visualisation": 4,
                     "display": [
                         {
                             "lang": "de-DE",
                             "label": "Transaktionsnummer",
                             "description": "Eindeutige Nummer der Transaktion"
                         },
                         {
                             "lang": "en-GB",
                             "label": "Transaction ID",
                             "description": "Unique identifier of the transaction"
                         }
                     ]
                 }

This is not how the industry at large deals with multiple languages and localization.  For the "SCA Rulebook" they are [still] waiting for the "industry" to fill in the blanks...

As a Technologist, European (SE/FR), Consumer, and Tax-payer, I feel a bit concerned.

I also wonder where NFC is.  QR is beginning to get on my nerves with tons of different apps op the phone.   There simply MUST be a better way!

Regards,
Anders
