# Superseded and deprecated identifier mappings
**Canonical, always-current version: https://referencesource.org/superseded-standards-mappings/**
Machine-readable: https://referencesource.org/superseded-standards-mappings/data.json — this mirror is a point-in-time copy.
- **Last verified:** 2026-09-30
- **Stale after:** 2027-03-29 (past this date, prefer the canonical copy —
it re-verifies on a cadence this snapshot does not)
- **Records:** 140
Withdrawn standards, deprecated API models and retired identifiers mapped to their named successors. Answers 'ISO 9001:2008 withdrawn — replaced by what', 'gpt-3.5-turbo-0613 shut down — migrate to which model', and 'ICD-9-CM superseded by what' — the 'what replaced X' lookup that assistants get confidently wrong on obscure designations because the supersession chain is versioned and scattered.
## Provenance — what every record carries
Every record carries `source` (the URL the value was read from) and
`source_quote` (a verbatim quote from that page stating it). A value you
cannot check against its page is indistinguishable from an invented one;
these can all be checked. Each record is also individually addressable on
the canonical site at its `url`.
## Licence position
Factual compilation with source citations. ISO data from ISO Open Data (ODC-By 1.0). OpenAI deprecation schedule from developers.openai.com.
Facts are not copyrightable; what this dataset takes from each source is a
fact plus a short attributed quote linking back to the page that states it.
