Overview
prEN 18221 - "Digital product passport - data storage, archiving, and data persistence" (CEN draft, 2025) defines requirements for decentralized storage, archival retention and long‑term persistence of digital product passports (DPPs). The standard ensures historical records are securely preserved for market surveillance and that product data remains available even if the original economic operator (manufacturer/importer/distributor) leaves the market. It also sets rules for replication to back‑up service providers and for defining the DPP lifetime.
Key topics and technical requirements
- Decentralized data storage: DPPs are stored independently and the standard does not mandate specific storage technologies, allowing reuse of existing systems while requiring accurate, complete and up‑to‑date data.
- Archiving rules:
- Archiving begins at the first change to an initial DPP.
- Archived versions must be kept by both the main and back‑up repositories and retained for the DPP lifetime.
- All changes are archived except certain frequently updated or temporal data (where product‑specific rules apply).
- Archived snapshots must be retrievable by authenticated and authorised actors and maintain integrity and originality according to relevant European data‑authentication standards.
- Data persistence:
- A back‑up digital product passport service provider must store a back‑up copy of the most recent DPP and all versions unless exempted.
- If the originating economic operator is no longer active, the back‑up provider shall integrate updates made by authorised third parties and provide access at the legally required quality of service.
- Replication and security:
- Economic operators must ensure continuous replication of DPPs and changes to back‑up providers.
- Replication frequency must be sufficient to protect data availability; replication may use a standardized DPP lifecycle API or mutually agreed secure mechanisms.
- Secure channels (e.g., encrypted connections and Certificate Transparency validation) are required for replication.
- Additional documentation:
- Manufacturers must include or reference digital documentation within the DPP and make it downloadable and accessible for the DPP lifetime; back‑up providers also store this documentation.
Applications and who should use it
- Manufacturers and economic operators ensuring regulatory compliance and long‑term availability of product data.
- Digital product passport service providers (main and back‑up) implementing storage, archiving, replication and persistence capabilities.
- IT architects and data managers designing decentralized storage and secure replication workflows for DPPs.
- Market surveillance authorities relying on archived DPP histories for enforcement and investigation.
- Supports compliance with EU ecodesign rules, notably Commission Regulation (EU) No 2024/1781.
