# FHIR R4 fixture provenance

`patient-bundle.json` is a reduced and curated derivative of a synthetic FHIR
R4 patient Bundle generated by [Synthea](https://github.com/synthetichealth/synthea).
The source Bundle was obtained from the official
[Synthea sample data downloads](https://synthetichealth.github.io/synthea-sample-data/downloads/latest/).

The Patient, Condition, laboratory Observation, Procedure, and
MedicationRequest examples retain the structure and synthetic terminology used
by Synthea. Convert-Pheno contributors reduced those resources and added a
Specimen, a specimen-linked Observation, an HPO-coded Observation, a
ResearchStudy, a ResearchSubject, and a Group to exercise the supported mapping
boundaries. These additions are project-authored synthetic test data and do not
represent a real person or study.

## mCODE fixture

`mcode-patient-bundle-jenny-m.json` is the complete, unmodified extended
example Bundle published with the official [mCODE 4.0.0 implementation
guide](https://hl7.org/fhir/us/mcode/Bundle-mcode-patient-bundle-jenny-m.json).
It was retrieved on 2026-08-02. The corresponding source release is
[`4.0.0`](https://github.com/HL7/fhir-mCODE-ig/tree/4.0.0), commit
`543477b5585f2dcc717820a2bea141ea85f03012`.

The fixture is synthetic and exercises the mCODE Patient Bundle, primary
cancer condition, TNM stage, treatment, genomic, specimen, performance-status,
and tumor-marker profiles. The mCODE implementation guide is distributed under
the [CC0 1.0 license](https://github.com/HL7/fhir-mCODE-ig/blob/4.0.0/LICENSE).
