Semantic Web Research
Verisav actively contributes to the development of the Semantic Web by creating and publishing standard RDF/OWL vocabularies for after-sales service and product traceability.
Verisav is committed to applied research to develop open and interoperable standards. Our RDF/OWL vocabularies are designed to enable structured data exchange between all actors in the after-sales service ecosystem.
By publishing our vocabularies on Linked Open Vocabularies (LOV) and aligning them with international standards (Schema.org, UNTP, GS1), we contribute to the emergence of a linked data ecosystem for circular economy and product traceability.
Vocabularies published on LOV
Three RDF/OWL vocabularies created by Verisav and accepted in the Linked Open Vocabularies registry
Digital Product Passport Vocabulary
Vocabulary for the Digital Product Passport compliant with European ESPR 2024/1781 regulation. Defines classes and properties for traceability, carbon footprint and regulatory compliance.
Return Merchandise Authorization Vocabulary
Vocabulary for return management and after-sales service. Models service tickets, diagnostics, interventions and communications between actors.
Warranty & Contracts Vocabulary
Vocabulary for machine-readable warranties and contracts. Enables automation of warranty decisions and extension management.
Understanding our vocabularies
The logic in 3 steps
- 1A product has a record (DPP): identifier, market date, compliance.
- 2When a customer reports an issue, we create a service ticket (RMA) linked to that product.
- 3The warranty (WTY) indicates whether repair or replacement is covered.
What are they for?
Our three vocabularies (DPP, RMA, WTY) provide a common language for after-sales data:
- · Product traceability: origin, composition, carbon footprint (DPP).
- · After-sales ticket management: tickets, diagnostics, interventions (RMA).
- · Machine-readable warranties: coverage rules, extensions (WTY).
- → Result: manufacturers, distributors, repairers and software all speak the same language.
How does it work?
- 1. Each concept (product, ticket, warranty) is defined by RDF/OWL classes and properties.
- 2. Data is described using these terms (stable URIs) instead of free-text fields.
- 3. Systems that know these vocabularies can read, validate and link data automatically.
Usage examples
Example: ticket rma:ticket-456 concerns product dpp:product-123.
Example (Turtle/RDF):
@prefix dpp: <https://ns.verisav.fr/dpp#> . @prefix rma: <https://ns.verisav.fr/rma#> . dpp:product-123 a dpp:Product ; dpp:name "Lave-linge X" ; dpp:marketDate "2024-06-01" . rma:ticket-456 a rma:ServiceTicket ; rma:status rma:InProgress .
- · A product with its DPP (identifier, market date, compliance).
- · A service ticket with status, diagnosis and link to the product.
- · A warranty rule: "covered if purchase < 2 years and material defect".
