Verisav Semantic Vocabularies

Open RDF/OWL standards for EU Digital Product Passports (ESPR 2024/1781), after-sales (RMA), and machine-readable warranties (WTY).

Why now (EU DPP landscape, 2026–2030)

The Ecodesign for Sustainable Products Regulation (ESPR, EU 2024/1781) is in force. Digital Product Passports are introduced sector by sector via delegated acts—not a single “big bang” date:

Horizon	Sector / topic	Relevance for implementers
2026	Destruction ban for unsold consumer goods (Art. 25); annual reporting	Retail & brand compliance
18 Feb 2027	Battery passports (Battery Regulation)	First large-scale mandatory DPP class
2027–2029	Textiles, tyres, building products, metals (working plans)	Delegated acts + 18–36 month rollout typical
2029–2030	Detergents, toys, furniture (indicative)	Long-tail product categories

Verisav vocabularies are built for machine-readable, interoperable data—not PDF brochures: JSON-LD/Turtle, GS1 Digital Link, UNTP DPP, JRC 2026 methodology themes (essential vs recommended tiers), W3C Verifiable Credentials (VCDM 2.0), and EU Business Wallet / EUID operator identity—aligned with EU registry and semantic-web practice (data.europa.eu DPP, CIRPASS-2, GS1 Europe DPP).

Overview

Three complementary RDF/OWL vocabularies standardize after-sales and product passport data:

Vocab	Role	Version (live)	Namespace
DPP	Digital Product Passport · ESPR · traceability · VC/EBW	1.5.2	https://w3id.org/verisav/dpp#
RMA	Returns & service tickets	1.0.0	https://w3id.org/verisav/rma#
WTY	Machine-readable warranties & payment rules	1.0.0	https://w3id.org/verisav/wty#

Quality bar

• Validated on LOV (Linked Open Vocabularies)
• W3ID persistent URIs (W3C community)
• Content negotiation (Turtle, JSON-LD, HTML)
• SHACL + JSON Schema per vocabulary (validation/*.shacl.ttl, validation/*.schema.json)
• CHECKSUMS.sha256 for published artefacts
• Schema.org-compatible patterns for the open web

DPP highlights (v1.5.x)

Beyond core product lifecycle (warranty, repair, work orders):

• ESPR / policy graph: rdfs:seeAlso to ESPR, Data Act, Interoperable Europe Act, Commission ESPR hub, JRC methodology, CEN/CENELEC ESPR work
• Interoperability: GS1 Digital Link URI syntax, GTIN/GLN, UNTP DPP, ISO/IEC 19987 (EPCIS), W3C DID 1.0
• EU identity & trust: EU Business Wallet, EUID, W3C Verifiable Credentials (@verisav/dpp-verifiable-credentials on npm)
• Trade & customs (v1.3+): country of production, due diligence, dimensions
• OWL-DL consistency (v1.5.0+)

Package	Purpose
@verisav/dpp-verifiable-credentials	Issue/verify W3C VCs for DPP (Veramo, EBW-ready)
@verisav/graphql-rdf-vocabularies	GraphQL API over TTL vocabularies (DPP, RMA, WTY)

  }
}

Turtle

@prefix dpp: <https://w3id.org/verisav/dpp#> .

<https://example.com/product/123> a dpp:ProductPassport ;
    dpp:serialNumber "ABC123456" ;
    dpp:purchaseDate "2025-07-25"^^xsd:date .
