Digital Product Passports for the EU — built standards-first.
OpenDPP is a B2B Digital Product Passport service for the EU Ecodesign for Sustainable Products Regulation (ESPR) and the Battery Regulation. Every public passport URL serves standards-conformant, independently verifiable output under HTTP content negotiation — so a passport is consumable by IDTA AAS tooling and W3C Verifiable Credential verifiers alike, not just by us.
- AAS / IDTA —
application/aas+json+ AASX, conformant to IDTA-01001-3-1 (AAS v3.0/3.1). - UNTP + W3C VC — enveloping
vc+jwt(VC-JOSE-COSE) or embeddedvc+ld+json(W3C Data Integrity,ecdsa-jcs-2019), conformant to UNTP DigitalProductPassport v0.7.0, withdid:webissuer keys and W3C Bitstring Status List revocation.
- 🔗 Live service: opendpp-node.eu
- 📦 opendpp-interop — the open interop boundary: official schemas, validated samples, a runnable conformance validator, the OpenAPI contract, and the field mappings. Everything you need to integrate without access to the product source.
- 📖 API reference: opendpp-node.eu/api-reference · machine-readable: openapi.json
- 🤖 opendpp-knowledge — the API as a machine-readable OKF (Open Knowledge Format) bundle for AI agents: cross-linked Markdown concepts for every endpoint, schema and webhook, regenerated on each API version. Served live at opendpp-node.eu/okf and advertised via llms.txt.
Small, Apache-2.0 npm packages that make integrating with the node easier — all provenance-backed:
- 📦
@opendpp/sdk— the full typed API client, generated from the OpenAPI contract (opendpp-sdk). - 📦
@opendpp/gs1— GS1 Digital Link builders + mod-10 / GLN check-digit helpers. - 📦
@opendpp/csv— CSV → passport mapper to the public ingest shape (bulk import). - 📦
@opendpp/webhooks— webhook event types + a constant-time HMAC-SHA256 signature verifier.
npm install @opendpp/sdk # or @opendpp/gs1, @opendpp/csv, @opendpp/webhooksThe interoperability contract is open (this org). The product backend — tenancy, key custody, billing, the SSR/portal application — stays private. You never need the backend to consume or conform to OpenDPP output.
OpenDPP is an ESPR-readiness / interoperability node: it produces validator-conformant, independently verifiable output. Regulatory compliance is a determination for the operator and the competent authority.
