## CMExam license evidence

The official README restricts use to academic research and prohibits commercial misuse; the unofficial mirror card does not count

## Source and lineage

National Medical Licensing Examination

## Known issues with CMExam

- The code repository license is Apache-2.0, coexisting with the README restriction
- The HF version is an unofficial preprocessed copy; its card also says academic research only
- Sources include national medical licensing exam questions; in August 2026 the National Medical Examination Center issued a statement asserting copyright over past exam questions, so there is a source copyright risk

## Citing CMExam

No recommended citation text.

## Machine-readable

- JSON: https://mdexa.com/datasets/cmexam.json
- 2026-11-13 Added specialty tags: multi-specialty(inferred).
- 2026-11-13 Removed the stored size-tier tag; the tier is now computed from the size field when pages are built.
- 2026-11-13 Added dataset-level tags: 5 (2 stated by the authors with excerpts, 3 inferred from the content). No conclusion changed.
- 2026-11-12 License status changed from conflict to restricted: restrictions are read broadly (official README restriction applies to the data); third-party mirror pages are secondhand.
- 2026-11-12 Recorded the code repository license separately; it is not treated as a data license statement.
- 2026-11-12 Added verbatim license excerpts and snapshot ids from captured page snapshots; no conclusion changed.
- 2026-11-12 License status split into license_status (what the license says) and hosting (what Mdexa does); the earlier conclusion is kept for traceability.
- 2026-11-12 Card converted from an earlier manual catalog; no new facts added; reclassified under taxonomy v2.
