This document defines the principles and specifies the requirements and guidelines for unique product identifiers, unique economic operator identifiers, and unique facility identifiers used in digital product passports. It covers the following areas: a) global uniqueness; b) persistence; c) syntax; d) semantics; e) interoperability; f) openness. This document accommodates unique product identifiers at three granularity levels of specificity: model, batch, or individual item, to support various operational needs. This document describes identification (ID) schemes that use issuing agencies, self-issuing systems, or a combination of both.

This document specifies requirements for decentralized data storage, archiving and data persistence of digital product passports. 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 digital product passports remains available even when the economic operator creating the digital product passport is no longer active. This document also specifies requirements for the replication between economic operators and back-up operators as well as rules for data lifetime definition.

This document aims to standardize the specifications for the API of the Digital Product Passport (DPP) as mandated by the ESPR of the European Commission. The purpose of this API is to facilitate the searchability of DPPs, as well as to provide the necessary means for interactions throughout the lifecycle of a product's DPP.

The scope of this document includes: — the semantic description of a product, including its properties where relevant and the semantic aspects to represent the product lifecycle; — a common information model allowing for the implementation of data dictionary systems; — metadata models and formats to be used in exchange and representation, allowing for the integration of dictionaries; — rules on how to systematically use such metadata models when developing product group specific data models and dictionaries; — technical and organizational interoperability. This document follows the approach of standard interoperability layers and proposes the following aspects in this regard.
