OpenEPCIS CPR Vocabulary - Artefacts
Vocabulary for the revised EU Construction Products Regulation (Regulation 2024/3110, in force 2025-01-07; DPP via delegated acts from 2026 onward, phased per product family). This module is intentionally thin per the project's four-layer delegation pattern. The construction-specific concepts live here; cross-cutting concerns (recycled content, carbon footprint, hazardous substances, recyclability, EPR, end-of-life, due diligence) reuse the lifted `dpp:` vocabulary plus `untp:` and `gs1:`.
