Another document published by the @w3c Verifiable Credentials #WorkingGroup: "Verifiable Credential Barcodes v1.0".
This specification defines how to embed #VerifiableCredentials in optical barcodes (like those on drivers' licenses) and secure them using a compact format that fit within 150 bytes and can be printed in standard 2D barcodes #FPWD #timetogiveinput

The @w3c Verifiable Credentials #WorkingGroup published VCALM 1.0. This spec. defines a standardized set of HTTP #APIs for managing the entire lifecycle of #VerifiableCredentials to improve #interoperability between systems. This covers issuance, presentation, verification, and exchange #timetogiveinput #FPWD

The Verifiable Credentials Working Group published a First Public Working Draft of Verifiable Credentials Data Model v2.1.

This specification describes the extensible data model for verifiable credentials, how they can be secured from tampering, and a three-party ecosystem for the exchange of these credentials that is composed of issuers, holders, and verifiers.

📆 1 April 2026 - tomorrow!
@p20n will present: "Unlocking Value with Emerging Technologies in Freight Forwarding" at the 2026 Intl Federation of Freight Forwarders Assoc meeting in Geneva 🇨🇭

He will present W3C's Verifiable Credentials family of specification, including the upcoming work of the newly rechartered Working Group in domains related to this event (such as the vocabularies for Digital Product Passports and for Business Wallets).

The JWT ecosystem already uses this principle: IANA maintains a centralised registry of claim definitions — a semantics-linking mechanism.
@context achieves the same binding, but decentralised and domain-controlled. Which is what the rulebook model requires.

"Semantics are essential but linking credentials to their semantics is unnecessary" is a contradiction.

A recurring objection to my EUDI Wallet analysis: "Semantics come from rulebooks, not JSON-LD. @context is unnecessary."

I agree with the premise. Not the conclusion.

If vocabularies are in rulebooks, how does a credential tell a verifier which rulebook governs it? @context is a machine-readable link from the credential to its vocabulary. Not embedding semantics — linking to them.

EdTech companies, European EdTech Alliance, national associations:

Have Your Say on EUDI Wallet regs is open until early March. A clear contribution explaining that your products use W3C-VC, the regulatory gap affects market access, and linked data is essential for semantic interoperability — this carries weight.

Collective industry input amplifies individual voices.

Full analysis for reference: see my pinned post.
