DATABASE_MATCH

Imported from CultureMech pipeline, quality=DIRECT_MATCH
MANUAL_CURATION
via MIM curation (#260)
Added 'Sodium sulfide' as a EXACT_SYNONYM (#260): the systematic name of the formula this record already carries; the record's own synonym list has `disodium sulfide` and `sodium sulphide`. NOT CHEBI:85357, which CultureMech asserts (CultureMech#276) — that term is 3-[(1E,4R)-4-hydroxycyclohex-2-en-1-ylidene]pyruvic acid, an organic acid with no sodium and no sulfur. CultureMech uses this surface form and label_index did not contain it, so the lookup missed. No new record: CHEBI:76208 is this record's identifier, and in MIM the identifier IS the ontology CURIE, so a second record on it would be a duplicate primary key rather than added coverage.

The record's label does not equal the term's primary label 'sodium sulfide (anhydrous)'; it matches the ChEBI synonym 'anhydrous sodium sulfide' on CHEBI:76208. The schema defines EXACT_MATCH as a direct match to the term and SYNONYM_MATCH as a match to a known synonym, so the recorded grade overstated. ontology_id is unchanged — the term is correct. The SSSOM predicate is unaffected (both grades emit skos:exactMatch). | |
