Digital Product Passports for construction, built on structured data

Dictagon gives construction products a structured, standardised data foundation aligned with the CPR 2024. From Data Dictionaries (EN ISO 23386) & Product Data Templates (EN ISO 23387) to digital DoPCs, Digital Product Passports and BIM objects.

We build to the harmonised DPP standards published in the EU Official Journal

What happens to your data

The data you already have

Input 01

Product and manufacturer data

  • Technical datasheets
  • Product and operator identifiers
  • Manufacturer details
  • Installation and safety information
Input 02

Technical performance

Essential characteristics and their declared performance under the harmonised standard.

Input 03

Environmental data

EPD indicators, where they exist for the product.

Sources

Whatever form your product data is in today.

Aggregated

Digital Declaration of Performance and Conformity

prEN 18357

Applied

Data dictionary, EN ISO 23386 / 23387

PDTs.pt data dictionary: what every data point means.

Generate

Dictionary-referenced data points, versioned against the standard.

The result

Digital Product Passport

One identifier for the product, readable by people and by systems.

EN 18219 · EN 18220 · EN 18223

Where it is used

Read by people

Architects and specifiers
Contractors and installers
Customers and end users
Market surveillance authorities

Read by systems

Product information and catalogue systems
Procurement and tender platforms
BIM authoring and specification tools
Life cycle assessment software

Stored and registered

Passport data store, versioned and backed up
Registered with the EU DPP Registry

The registry holds the passport identifier and a pointer to where the data lives, not the product data itself.

Kept current

Reviewed and regenerated as harmonised specifications are published and revised.

The DoPC is generated from the declaration and environmental data. The passport is built on top of it, together with the identifiers, datasheets and catalogue data. Under CPR 2024 the DoPC is eventually integrated into the passport.

Why the data dictionary layer decides everything downstream

A passport without data dictionary references is a document. With them, it is data that any system can read without being told what the fields mean.

“Reaction to fire” in your catalogue, “Resistência ao fogo” in a Portuguese specification and “Fire rating” in a customer's procurement system are three different things to a machine. A data dictionary reference is a URI that resolves to one definition, one data type and one unit, so all three are recognised as the same property.

EN 18223 requires exactly this: “a common information model allowing for the implementation of data dictionary systems.”

Three names, one definition

Portuguese specification

Resistência ao fogo

Customer procurement system

Fire rating

Your internal catalogue code

PROP_FIRE_01

The reference resolves to a single definition, so a machine recognises all three as the same property.

How it works

01

Every declared value gets a data dictionary reference

A URI from PDTs.pt, the Portuguese ISO 23386/23387 data dictionary, that means the same thing in every system.

02

Environmental data joins the same structure

EPD indicators are declared against the same product, in the same referenced form, not in a separate silo.

03

The digital DoPC is generated

A machine readable Declaration of Performance and Conformity, versioned against prEN 18357 and regenerated when it publishes.

04

The Digital Product Passport is built on top

Unique identifiers per EN 18219, a data carrier per EN 18220, registered with the EU DPP Registry, and readable by the systems that need it.
