OpenEPCIS PPWR Vocabulary - Artefacts
Vocabulary for the EU Packaging and Packaging Waste Regulation (Regulation 2025/40, in force from 2025-01-01; labelling from 2025-08-12; recyclability grading mandatory from 2030-01-01; minimum Grade B from 2038-01-01). This module is intentionally thin: nearly every PPWR data point reuses the cross-cutting `dpp:` and `untp:` vocabulary already lifted to common/core. Packaging-specific concepts only live here: - `ppwr:Packaging` (subClassOf gs1:Packaging) - `ppwr:packagingTier` (Sales / Grouped / Transport — Article 3) - `ppwr:recyclabilityGrade` (A / B / C — Article 4, Annex II) - `ppwr:harmonisedSymbol` (URI of an Annex IX symbol code) Recyclability scoring/rate, recycled content, reuse, compostability, bio-based content, hazardous substances, EPR, deposit-return, production site, declaration of conformity — all use existing `dpp:` / `untp:` / `gs1:` terms.
