The record's label does not equal the term's primary label '2-Amino-4-hydroxy-6-pteridinecarboxylic acid'; it matches the ChEBI synonym 'Pterin-6-carboxylic acid' on CHEBI:88937. 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). | |
| 2026-08-24T00:00:00+00:00 | regrade_synonym_matches | REGRADED_TO_CAS_RN_LOOKUP | mapping_quality SYNONYM_MATCH -> CAS_RN_LOOKUP (#317). The record was created by an explicit CAS-to-ChEBI lookup and its current CAS RN 948-60-7 uniquely resolves by ChEBI xref to CHEBI:88937 '2-Amino-4-hydroxy-6-pteridinecarboxylic acid'. CAS_RN_LOOKUP records the method that established this mapping; a lexical grade would discard that provenance. ontology_id is unchanged. The own-identifier SSSOM predicate remains skos:exactMatch under Rule D (#438), independently of mapping quality. |
