Property & unit reference

Every quantity you author — {"value": 5.0, "unit": "Ah"} under a properties key — is mapped to an EMMO class, and every unit symbol to a unit IRI, by the curated mapping tables under assets/mappings/domain-battery/ — the single source of truth for the semantics of emitted JSON-LD. This page is generated from those tables.

Unknown keys and symbols are refused, not guessed — see the validation contract for how mapping gaps surface as machine-readable issues.
