OpenEPCIS Iron & Steel Vocabulary
Vocabulary for the iron & steel ESPR priority product group (Regulation (EU) 2024/1781 Annex I; iron & steel named in Article 5 / the 2025-2030 working plan). Covers steel-specific identification (heat / cast / lot numbers, grade classification per EN 10020 and designation per EN 10027), production route, and the Material Test Certificate (EN 10204 inspection documents with EN 10168 mechanical and chemical parameters). This module is intentionally thin per the project's four-layer delegation pattern. Steel-specific concepts live here; cross-cutting concerns (recycled content, substances of concern, environmental product declaration, carbon footprint, documents) reuse the lifted `oec:` vocabulary plus `untp:` and `gs1:`. Aligned with the DPP Keystone iron & steel profile (dppk:IronSteelProduct / dppk:MaterialTestCertificate).
https://ref.openepcis.io/extensions/eu/iron-steel/This vocabulary builds on GS1 standards (Digital Link, EPCIS 2.0, Web Vocabulary) but extends them with properties not yet defined by GS1. The GS1 DPP Provisional Standard is still under development. Our extensions may be superseded by official GS1 terms as they emerge. Feedback welcome!
