DPP Interoperability
The principle that a Digital Product Passport must be readable and meaningful regardless of which vendor created it, which scanner reads it, or which member state queries it.
Interoperability is enforced through shared standards — GS1 identifiers, GS1 Digital Link resolution, common data models (W3C Verifiable Credentials, JSON-LD), and sector-specific data schemas defined under ESPR delegated acts.
Brands that build on proprietary data formats risk having to rebuild their passports when the formal standards land. Building on GS1 and CIRPASS-aligned models is the lowest-risk path.
