| 2026-01-28T19:48:21.419173Z | chebi-enrichment | Added CHEBI ontology terms to ingredients | Enriched using MicrobeMediaParam and MediaDive chemical mappings |
| 2026-03-13T06:20:12.525542Z | culturemech-id-assigner-v1.0 | Assigned CultureMech ID | Assigned stable identifier: CultureMech:010265 |
| 2026-03-17T06:30:11.000000Z | mediaingredientmech-enrichment-v1.0 | Added MediaIngredientMech links | Linked ingredients to MediaIngredientMech identifiers |
| 2026-03-17T19:46:31.469732+00:00 | normalize_media_names_to_snake_case.py | NAME_NORMALIZED | Normalized name from "9K Medium" to "9k_medium" for consistent matching |
| 2026-06-05T07:40:45.005073+00:00 | mim-legacy-to-chebi-migration-v1.0 | Refreshed legacy MediaIngredientMech links to CHEBI keying | Replaced 5 legacy mediaingredientmech_term link(s) with mediaingredientmech_chebi_term (id-safe: ingredient's own CHEBI + label). MIM deprecated the MediaIngredientMech:NNNNNN id scheme. |
| 2026-06-08T23:19:35.032160+00:00 | chebi-regrounding-v1.0 | Corrected CHEBI ingredient grounding (audit G21/G22) | Re-grounded 2 term reference(s) to the correct CHEBI (see reports/chebi_grounding_audit.md). Label-conditional fixes for pyridoxine/pyridoxamine, glycerol, MnSO4, Ca(NO3)2, selenate; casamino acids de-grounded (mixture, no single CHEBI). |
| 2026-06-10T06:57:33.434886+00:00 | mgso4-heptahydrate-term-fix-v1.0 | Corrected MgSO4·7H2O primary term grounding to heptahydrate | Re-grounded 1 heptahydrate-labelled ingredient(s) from CHEBI:32599 (generic magnesium sulfate) to CHEBI:31795 (magnesium sulfate heptahydrate). Generic/hexahydrate labels untouched. |
| 2026-06-10T07:46:51.809617+00:00 | primary-term-label-canonicalization-v1.0 | Canonicalized primary term label to OBO canonical (OAK) | 3 primary term(s); ingredient name resolved by OAK sqlite:obo:chebi. |
