Structuring the Data Schema
A Digital Product Passport is ultimately just structured data. It requires a standardized schema so that any downstream stakeholder (a recycler in Germany, an auditor in France) can read your product's lifecycle data without logging into your proprietary portal.
Draft Core Attributes
While the final delegated act for electronics is still pending, the expected schema heavily borrows from existing IEC and ISO standards. A cable assembly DPP will likely require:
- Global Trade Item Number (GTIN) or equivalent unique identifier.
- Manufacturer Details: Verified credentials of the entity placing the product on the market.
- Material Composition: A breakdown of copper, aluminum, specific polymer grades, and additives.
- Compliance Declarations: Links to RoHS, REACH, and CE declarations of conformity.
- Carbon Footprint: Structured LCA data (Scope 3) detailing emissions per unit.

Decentralized Architecture
The EU is leaning towards a decentralized model. You will not upload your data to a massive central EU database. Instead, you will host the data (or use a service provider) and register only the product identifier and a link (resolver) to your dataset.
