Standards Development

Scope

This document aims to define a standard for secure and efficient data exchange protocols and data formats to be used for the Digital Product Passport. Data exchange protocols establish the rules and procedures that systems follow when communicating and exchanging information. Data formats define the structure and presentation of that information so it can be understood and processed correctly by the involved systems. Together, protocols and formats ensure that data can be exchanged in a manner that is both secure, reliable, and compatible across various platforms and sectors. The standard being developed will ensure seamless data exchange between systems by defining both the protocols and formats. This will guarantee that data is machine-readable, structured, searchable, and transferable through an open, interoperable network without vendor lock-in.

The scope of the proposed work includes:

• Secure Communication:

 Identify and define protocols that ensure secure and authenticated data exchange between systems, ensuring that all information follows the established data formats. (In agreement with Module 4)

 Collaborate with Working Group 3 to define security measures that protect data against unauthorized access and ensure only authorized entities can access the information, maintaining both protocol and format integrity.

• Interoperability for data exchange:

 align the core principles of a framework in agreement with module 4 that avoids vendor lock-in , ensuring that both the protocols and data formats allow for efficient data exchange. Ensure compatibility of protocols and formats across various sectors and allowing multilingual environments, supporting a wide range of applications and use cases.

 Include a focus on data serialization, ensuring the formats are aligned with interoperability goals. (In agreement with Module 4)

• Ease of Use and Integration:

 Ensure that the identified protocols and formats can be implemented easily, especially for mobile devices, and are userfriendly to facilitate widespread adoption.

• Data Integrity:

 The protocols and data formats must ensure the integrity of information linked to physical objects and electronic data throughout the entire value chain, extending to the product's or asset's end-of-life.

• Documentation and Discoverability:

 Provide detailed guidelines for documenting both the protocols and data formats, ensuring they are easily discoverable, understandable, and accessible for users across different knowledge levels.

 Ensure that the protocols and formats are accessible to individuals who may not have specialized knowledge in this field.

To promote interoperability, reduce costs for businesses, and align with existing European regulations and initiatives, the standard considers both the data exchange protocols and data formats already in use in other legislations aligned with the technical interoperability in module 4. Relevant existing standards are integrated into the development process to ensure consistency and coherence with industry practices and regulatory frameworks.

The document will:

 Provide comprehensive guidelines for documenting both the protocols and formats, ensuring they are easily discoverable, understandable, and aligned with existing standards.

 Ensure that the protocols and formats are accessible to individuals who may not have specialized knowledge, enabling broader adoption across sectors.

Purpose

This proposal is in response to the Standardization Request from the European Comission for the Digital Product Passport, as seen in “COMMISSION IMPLEMENTING DECISION of 31.7.2024 on a standardisation request to the European Committee for Standardisation, the European Committee for Electrotechnical Standardisation, and the European Telecommunications Standards Institute as regards digital product passports in support of Union policy on ecodesign requirements for sustainable products and on batteries and waste batteries” (C(2024) 5423 final). As specified in the Annex I, module 5, requesting a standard on “data processing, data exchange protocols and data formats”.

The NWIP will take offset in the description of data exchange protocols, as mentioned in Module 5 of the Annex, see below.

5) Standard(s) on data processing, data exchange protocols and data formats

5.1) The standard(s) shall define, inter alia, rules related to the following:

a) data exchange protocols, including rules to exchange data between two or more parties;

b) processes to introduce, modify, and update information in the product passport. 5.2) Existing relevant standards shall be duly considered when drafting the new European standard(s). A nonexhaustive list is provided below:
