Standards Development

Scope

The scope of this pwi follows the requirements of module 6 in the standardisation request of the european commission.

In Scope:

- rules for decentralised data storage

- rules for archiving and data persistence.

- Definitions for decentralized redundant secure storage of historical passport data

- Rules for replication between economic operators and backup operators

- Rules for data life time definition (in cooperation with module 8)

Out of Scope:

- User identification and legitimation

- Data exchange

- How internal representation of data is done is out of scope

- European standard(s) on unique identifiers

- European standard(s) on data carriers and links between physical product and digital representation

- European standard(s) on access rights management, information, system security, and business confidentiality

- European standard(s) on interoperability (technical, semantic, organisation)

- European standard(s) on data processing, data exchange protocols and data formats

- European standard(s) on data authentication, reliability, integrity

- European standards on Application Programming Interfaces (APIs) for the product passport lifecycle management and searchability

Purpose

This proposal is in response to the Standardization Request from the European Comission for the Digital Product Passport, as seen in the latest version of document CEN/CLC/JTC 24 M-XXX DPP_N63_FINAL draft SReq DPP + Annexes - Document under CoS vote until 2024-04-01 (EN version) or https://ec.europa.eu/transparency/comitology-register/screen/documents/096100/1/consult?lang=en

As specified in annex 2 - part B - Section 6 - Standards on data storage, archiving and data persistence The standard(s) shall define rules for decentralised data storage, archiving and data persistence. The archiving service securely stores historical passport data, preserving a comprehensive record of past information. This feature is particularly relevant for market surveillance purposes. Persistence is required to make sure that data included in the product passports remains available even when the economic operator creating the passport is no longer active.

Existing relevant standards shall be duly considered when drafting the new European standard(s). A non-exhaustive list is provided below:

 EN IEC 63278: Asset Administration Shell for Industrial Applications

 Decentralized Web Node (available at: https://identity.foundation/decentralized-web-node/spec/)

 Encrypted Data Vaults (available at: https://identity.foundation/edv-spec/)

 Certificate Transparency (IETF RFCs 6962 and 9162 available at https://datatracker.ietf.org/doc/rfc6962/ and https://datatracker.ietf.org/doc/rfc9162/)

Besides the abovementioned standards from the Standardisation Request, the PWI will also take into account the following standards:
