Odal Node
Alpha — Odal Node is in active development. APIs, schemas, and docs may and will change before 1.0.

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

Section titled “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.

The European system standards, tracked clause by clause

Section titled “The European system standards, tracked clause by clause”

The European DPP system standards — written by CEN/CENELEC JTC 24, in the EN 182xx series — are landing in stages, covering exchange, identifiers, data carriers, storage, lifecycle APIs, interoperability, access rights and data authentication.

We are tracking that series, not claiming conformance to it, and the distinction is deliberate. These are paid standards and we have not purchased the texts. Nobody here has read them, so there is no clause-by-clause matrix and no basis on which we could assert that our identifier, carrier, API or authentication semantics align with what they actually say. We would rather state that plainly than describe an alignment nobody could check.

What we have built to instead are the open, published specifications those standards draw on — GS1 Digital Link, W3C Verifiable Credentials, did:web, the IDTA Asset Administration Shell — all of which are readable by anyone evaluating this claim. When the EN texts are purchased and read, this page will say what was found, including where it disagrees with what we built.

One further nuance that will still apply then: even a published standard is available but not yet harmonised (cited in the Official Journal), so presumption of conformity is a claim for the day that citation lands, not before.
