X — MIM

Ontology mapping

Primary identifier: UNMAPPED_0818
Notes: Imported from CultureBotHT (consolidated_media.json (media-only)). Used in 101 CultureBot media; samples: Wolfe's mineral mix, Wolfe's mineral mix_minus_Nitrilotriacetic_acid, Wolfe's vitamin mix…. No CAS-RN or CHEBI mapping available; curator review needed. Unmapped from NCIT:C189218 (#356). The term's definition is 'The 24th letter of the English alphabet' — it is not a substance, so this record published a meaningless node at EXACT_MATCH confidence across 101 occurrences. The grade was not wrong about the STRING: the record label and the term label are both 'X', which is how a name-normalisation pass produced it from UNMAPPED_0256. Nothing in that path checked the result was a chemical. What 'X' denotes is still unknown and is deliberately not guessed here — it needs source archaeology in the CultureBot media that use it. UNMAPPED states that honestly; the previous mapping is retained in this history.
