FHIR Dataset
A collection of HL7 FHIR R4 resource instances (JSON), organized by resource type. The
data is aggregated from public FHIR example sets, a public FHIR test server, and
synthetic patient data generators, then deduplicated by resource id within each type.
Contents
Resources are grouped into one folder per FHIR resource type, e.g. Patient/,
Observation/, Encounter/, Condition/, MedicationRequest/, etc. Each folder
contains one JSON file per resource instance.

Sources
Data was assembled from the following public FHIR sources:
- HL7 FHIR R4 examples — the official HL7 FHIR R4 example resource bundle, published by HL7.
- MIMIC-IV FHIR Demo — a FHIR-formatted demo subset of the MIMIC-IV critical care dataset, published on PhysioNet.
- FHIR SANER Implementation Guide — HL7's Situational Awareness for Novel Epidemic Response (SANER) implementation guide.
- HAPI FHIR public test server — a public, shared FHIR
R4 reference server used to pull additional resource instances via its search API,
paginating through
nextlinks and deduplicating by resourceid. - Synthea sample data (STU3, Sep 2019) —
synthetic patient records generated by Synthea,
an open-source synthetic patient population simulator. Transaction bundles were
split into standalone per-resource JSON files and deduplicated by
idagainst existing records.
Collection notes
- Resources pulled from the shared HAPI FHIR server were capped at a pragmatic limit per resource type (rather than exhaustive pagination) to avoid placing excessive load on a shared public server. For most resource types, the server was fully exhausted before hitting that cap.
- Records were deduplicated by resource
idwithin each resource type across all source passes, so a givenidappears at most once per folder. - All data is either synthetic (Synthea) or de-identified/example data intended for public use (HL7 examples, MIMIC-IV demo, HAPI public test server). No real patient data is included.
