Curation history

1. 2026-05-05T01:35:46.956313+00:00 · SEEDED_FROM_METPO · seed_from_metpo

   imported from data/raw/metpo.owl (OBJECT_PROPERTY)

2. 2026-05-10T00:00:00-07:00 · DEPRECATED_PROPERTY_RECORD · codex

   Deprecated generic chemical-use relation carrier; later replacement should use more specific trait records that combine the relation with the chemical, metabolic role, growth condition, and positive or negative usage context.

3. 2026-05-16T08:50:00-07:00 · UNDEPRECATED_AS_COMPOSITION_PRIMITIVE · claude

   Restored from DEPRECATED to REVIEWED under the predicate+class composition pattern (intended use: <organism> + this predicate + CHEBI chemical class). Added DOI/PMID-backed definition, evidence, and explicit domain/range slots.

4. 2026-05-16T09:35:00-07:00 · TIGHTENED_RANGE_TO_CHEBI_SUBCLASS · claude

   Narrowed range_ from http://purl.obolibrary.org/obo/CHEBI_24431 to http://purl.obolibrary.org/obo/CHEBI_51143 ('nitrogen molecular entity'). The earlier CHEBI:24431 root was used as a safe default during bulk un-deprecation (PR #54); the more specific CHEBI subclass better reflects the predicate's intended substrates.
