DPP standards.
GS1 Digital Link, GTIN, QR code/data carrier and JSON-LD as technical foundations for interoperable Digital Product Passports.
Standards
GS1 Digital Link.
GS1 Digital Link connects existing GS1 product identifiers with web URIs so a data carrier can point to product passport data, evidence and APIs.
Standards
GTIN.
The Global Trade Item Number is the stable GS1 identifier for a trade item and often the basis for DPP identity, variant logic and data-carrier URLs.
Standards
QR Code / Data Carrier.
The data carrier is the physical entry point to a Digital Product Passport: QR code, 2D code, NFC or another machine-readable carrier.
Standards
JSON-LD / Verifiable Credentials.
JSON-LD structures product passport data as linked data; Verifiable Credentials can represent selected evidence as verifiable digital claims.
