Description

Semantic identifier for the record and its LinkML identifier slot, but not a guaranteed unique document address: reviewed duplicate families may share a CURIE. For mapped ingredients this is the primary ontology, registry, or local identity (e.g. `CHEBI:26710`, `cas:247167-54-0`, `kgmicrobe.compound:aburamycin_a`); for unmapped ingredients it is a generated `UNMAPPED_NNNN` placeholder. The nested `ontology_mapping.ontology_id` is a grounding target: it equals `identifier` when the identifier itself names the grounded ontology term, but registry or local identities may legitimately differ from the ontology target at any evidence-backed mapping quality.
