These are the standards we work from to produce digital product passports. The status beside each one is the standard's own — published, or still in draft at CEN. A harmonised standard becomes operative when it is cited in the EU Official Journal; until then we do not claim compliance with it.
We are not reading these from the outside. Dictagon's founder is an expert in CEN/TC 442/WG 12, which is writing the DoPC standard, and participates in the CIRPASS-2 expert working groups on Digital Product Passports.
Two scope statements from the published standards. Neither is our claim. Both describe the data layer this company builds.
“a common information model allowing for the implementation of data dictionary systems”
EN 18223:2026
“through an open, interoperable network without vendor lock-in”
EN 18216:2026
Cited in the EU Official Journal. We build to these as published standards.
Digital product passport. Data exchange protocols
How passport data is exchanged, and the requirement that it move through an open network rather than a single vendor's system.
Secure, efficient data exchange protocols and formats. Data must be human and machine readable, structured, searchable and transferable through an open, interoperable network without vendor lock-in.
Committee: CEN/CLC JTC 24 · M/604 and M/604 Amd 1 · Regulation (EU) 2024/1781 (ESPR)
Digital product passport. Unique identifiers
The identifiers for the product, the economic operator and the facility, and how granular they are.
Unique product, economic operator and facility identifiers. Covers global uniqueness, persistence, syntax, granularity (model, batch or item), interoperability and openness.
Committee: CEN/CLC JTC 24 · M/604 and M/604 Amd 1 · Regulation (EU) 2024/1781 (ESPR)
Digital product passport. Data carriers
The QR code or other carrier on the product, and the link it makes between the physical item and its digital record.
Data carriers: symbology, format, error correction, encoding, print quality, durability, placement and machine readability, and the link between the physical product and its digital representation.
Committee: CEN/CLC JTC 24 · M/604 and M/604 Amd 1 · Regulation (EU) 2024/1781 (ESPR)
Digital product passport. Data storage, archiving, and data persistence
That passport data stays available even if the company that created it no longer exists.
Decentralised storage, archiving and persistence. Data remains available even when the economic operator that created the passport is no longer active, through replication with back-up operators and data lifetime rules.
Committee: CEN/CLC JTC 24 · M/604 and M/604 Amd 1 · Regulation (EU) 2024/1781 (ESPR)
Digital Product Passport. Application Programming Interfaces (APIs) for the product passport lifecycle management and searchability
The API through which a passport is created, updated, found and read by other systems.
The DPP application programming interface, covering searchability and the lifecycle interactions of a passport.
Committee: CEN/CLC JTC 24 · M/604 and M/604 Amd 1 · Regulation (EU) 2024/1781 (ESPR)
Digital Product Passport. System interoperability
The common information model that lets any system read a passport, including the rules for data dictionary systems.
Semantic description of a product and its properties: a common information model allowing the implementation of data dictionary systems, metadata models and formats allowing dictionary integration, rules for developing product-group-specific data models and dictionaries, and technical and organisational interoperability.
Committee: CEN/CLC JTC 24 · M/604 and M/604 Amd 1 · Regulation (EU) 2024/1781 (ESPR)
Digital product passport. Access rights management, information system security, and business confidentiality
Who may see which parts of a passport, and how commercially sensitive data stays protected.
Access rights management, IT security, data protection and the transfer of responsibility between operators. Public DPP data needs no access restriction to read.
Committee: CEN/CLC JTC 24 · M/604 and M/604 Amd 1 · Regulation (EU) 2024/1781 (ESPR)
Digital product passport. Data authentication, reliability and integrity
Proving a passport's data is genuine and has not been altered.
Integrity, authenticity and reliability of DPP data exchange, using electronically signed data constructs, for anti-fraud and anti-counterfeiting purposes.
Committee: CEN/CLC JTC 24 · M/604 and M/604 Amd 1 · Regulation (EU) 2024/1781 (ESPR)
The registry went live on 20 July 2026. A passport has somewhere to be registered, which is what turns these standards from documents into an operational requirement.
20 July 2026
The read operations of EN 18222 are live, and described by an OpenAPI document generated from the endpoints themselves rather than written by hand. A passport can be fetched by any of its identifiers, one data element collection at a time, with its attached documents and its authenticity block, and searched for by product information. Write operations are planned and not built.
At prEN stage with CEN/TC 442/WG 12. What we generate is versioned against the current text and regenerated when it publishes.
Digital declaration of performance and conformity (DoPC) of construction products. Methodology, general requirements and criteria to develop data templates
How a digital Declaration of Performance and Conformity is structured, and the criteria for developing the data templates behind it.
Guidance for digitalising the Declaration of Performance and Conformity for products CE marked under the CPR. It covers the structure used to declare a product's performance through its essential characteristics, including both technical properties and environmental sustainability performance, and applies to manufacturers issuing a DoPC under CPR 2024. The environmental information supports sustainability assessment developed under CEN/TC 350, using a revised EN ISO 22057 to digitalise LCA-based environmental indicators.

Long-published standards and the regulation itself. Everything above rests on these.
Methodology to describe, author and maintain properties in interconnected data dictionaries
How a property definition is authored and maintained so two systems mean the same thing by it.
The methodology behind a data dictionary: how properties are described, authored, versioned and maintained.
Committee: ISO/TC 59/SC 13
Data templates for construction objects
How properties are grouped into a data template for a product type.
Data templates for construction objects used in the life cycle of built assets, and their relationship to data dictionaries.
Committee: ISO/TC 59/SC 13
Library objects for architecture, engineering and construction
How a reusable BIM library object is structured and what data it carries.
Requirements for library objects used in architecture, engineering and construction, including the product data they carry.
Committee: ISO/TC 59/SC 13
Construction Products Regulation
What must be declared for a construction product, and the obligation to make declarations available digitally.
The regulation itself. It replaces Regulation (EU) 305/2011 and introduces the digital declaration and, in time, the construction product's Digital Product Passport.
Committee: European Parliament and Council
Sustainability of construction works. Environmental product declarations. Core rules for the product category of construction products
The core rules an environmental product declaration must follow.
Core product category rules for environmental product declarations of construction products, including the environmental indicators an EPD reports.
