| 2026-01-27T06:35:59.198965Z | togo-import | Imported from TOGO Medium | Source: NBRC, ID: M2169 |
| 2026-01-28T19:48:29.188052Z | chebi-enrichment | Added CHEBI ontology terms to ingredients | Enriched using MicrobeMediaParam and MediaDive chemical mappings |
| 2026-03-13T06:20:00.123441Z | culturemech-id-assigner-v1.0 | Assigned CultureMech ID | Assigned stable identifier: CultureMech:008763 |
| 2026-03-17T06:30:27.000000Z | mediaingredientmech-enrichment-v1.0 | Added MediaIngredientMech links | Linked ingredients to MediaIngredientMech identifiers |
| 2026-03-17T19:46:18.782986+00:00 | normalize_media_names_to_snake_case.py | NAME_NORMALIZED | Normalized name from "CGY Medium" to "cgy_medium" for consistent matching |
| 2026-06-05T07:40:53.027555+00:00 | mim-legacy-to-chebi-migration-v1.0 | Refreshed legacy MediaIngredientMech links to CHEBI keying | Replaced 2 legacy mediaingredientmech_term link(s) with mediaingredientmech_chebi_term (id-safe: ingredient's own CHEBI + label). MIM deprecated the MediaIngredientMech:NNNNNN id scheme. |
| 2026-06-08T23:19:36.287001+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). |
| 2026-08-20T19:01:37.002416+00:00 | apply_mim_groundings.py | Adopted MIM published grounding | Grounded 1 ingredient(s) from MIM's ingredient_mappings.sssom.tsv (2026-08-18), exactMatch only, where this record carried no CHEBI term (#308). |
