The record's label does not equal the term's primary label 'methionine'; it matches the ChEBI synonym 'DL-Methionine' on CHEBI:16811. 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). | |
