Open Data Standards for Digital Product Passports

Why Open Standards Matter

Open data standards are publicly available specifications that define how data should be structured, formatted, and exchanged. For Digital Product Passports, open standards are essential because DPP data must flow between many different systems, from manufacturers to regulators, recyclers, consumers, and market surveillance authorities.

Without open standards, DPP data would be locked into proprietary formats, limiting its usefulness and undermining the transparency objectives of the ESPR.

Key Standards for DPPs

Several established standards form the foundation of DPP data exchange:

• GS1 standards: product identification through GTINs, serial numbers, and data carriers
• JSON-LD and schema.org: semantic data formatting for web-accessible passport data
• ISO standards: environmental management (14000 series), quality (9000 series)
• W3C standards: linked data, content negotiation, and web accessibility
• ETSI standards: digital signatures and trust services for data verification

The ESPR Data Model

The European Commission is developing a harmonised data model for DPPs that builds on existing open standards. This model will define the mandatory and optional data elements for each product category, their formats, and the relationships between them.

The data model will be published as an open specification, allowing any platform to implement it and ensuring true interoperability across the DPP ecosystem.

Adopting Open Standards

Choose DPP platforms that embrace open standards rather than proprietary data formats. This protects your investment by ensuring your data remains accessible and portable, regardless of which platform you use.

MyProductPassport is built entirely on open standards, GS1 identifiers, JSON-LD data format, and standard web protocols, ensuring your product passport data is never locked in.
