Verisav Semantic Vocabularies

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

Canonical live publication: ns.verisav.fr · Persistent URIs: w3id.org/verisav · Registry: LOV / Verisav

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:

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).

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

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

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+)
