Standards & interoperability

A passport is only useful if the rest of the world can read it. The core speaks the open standards the regulation itself references, so a passport works with existing tooling rather than locking you into one vendor’s format.

The standards it speaks

• GS1 Digital Link — the identifier scheme behind the QR code on a product. A scan resolves the product to its passport, and the same link can serve different views to different audiences (a consumer, a recycler, an authority).
• W3C Verifiable Credentials with did:web — how a passport proves who issued it. Identity is anchored in the issuer’s own domain, so verification is an ordinary web lookup — no central registry, no blockchain, no dependency on Odal staying online.
• IDTA Asset Administration Shell — an industrial submodel projection, so a passport can flow into Industry 4.0 systems that already speak AAS.

Tracked as they finalise

Harmonised DPP standards (CEN/CENELEC JTC 24) are still being written. The core tracks them and updates as they land, so a passport stays aligned with the standard rather than a snapshot of it.
