  "description": "Vocabulary for the iron & steel ESPR priority product group\n(Regulation (EU) 2024/1781 Annex I; iron & steel named in Article 5 / the 2025-2030\nworking plan). Covers steel-specific identification (heat / cast / lot numbers,\ngrade classification per EN 10020 and designation per EN 10027), production route,\nand the Material Test Certificate (EN 10204 inspection documents with EN 10168\nmechanical and chemical parameters).\n\nThis module is intentionally thin per the project's four-layer delegation pattern.\nSteel-specific concepts live here; cross-cutting concerns (recycled content,\nsubstances of concern, environmental product declaration, carbon footprint,\ndocuments) reuse the lifted `oec:` vocabulary plus `untp:` and `gs1:`.\n\nAligned with the DPP Keystone iron & steel profile (dppk:IronSteelProduct /\ndppk:MaterialTestCertificate).",
