Description

Digital Product Passports (DPPs) under the EU Ecodesign for Sustainable Products Regulation (ESPR, Regulation 2024/1781) are central to keeping products and materials in circulation, enabling repair, reuse, remanufacturing and high-quality recycling. Roll-out is sector-by-sector: battery passports from February 2027; textiles, construction products and other categories via delegated acts through 2029–2030.

A key barrier for distributors, repairers, brands and SMEs is interoperable, machine-readable data. PDF brochures are not enough.

Verisav provides three complementary open RDF/OWL vocabularies: DPP (Digital Product Passport), RMA (returns and after-sales service) and WTY (machine-readable warranties). They are published under persistent URIs (W3ID, ns.verisav.fr), listed on Linked Open Vocabularies (LOV), and supported by SHACL shapes and JSON Schema for validation.

The DPP vocabulary (v1.5.2) aligns with ESPR policy references, JRC 2026 DPP methodology tiers, GS1 Digital Link, UNTP DPP, EPCIS, CIRPASS-2 practice, and W3C Verifiable Credentials / EU Business Wallet patterns for trusted operator identity.

Verisav also offers free public tools (DPP and repairability checks, JSON-LD generation), npm libraries for verifiable credentials, and an after-sales platform linking passport data with repair workflows—supporting circular value retention across EU value chains.

Main results
  • Live DPP vocabulary v1.5.2 with ESPR, Data Act and JRC methodology alignment; 
  • LOV-validated open standards with W3ID persistent URIs; 
  • SHACL and JSON Schema validation artefacts;
  • free Verisav Tools for DPP JSON-LD and repairability readiness; 
  • npm packages for W3C Verifiable Credentials (@verisav/dpp-verifiable-credentials); 
  • operational after-sales integration via RMA/WTY vocabularies. Replicable under CC BY 4.0 for EU implementers ahead of 2027 battery passports and subsequent ESPR sectors. 
  • Educational resource for policymakers, repair networks and SMEs adopting circular product data.
