What is Siming?

Siming is a clinical data server — it stores and searches clinical FHIR resources for small clinics. It is not a full terminology server: CodeSystem/ValueSet CRUD and operations ($expand, $lookup) are intentionally out of scope. Terminology validation is delegated to the optional HL7 Validator sidecar.

Designed as a lighter, faster alternative to HAPI FHIR for small clinics that cannot afford large infrastructure.

• 23 FHIR R4 resource types — full CRUD, search, history, transactions
• TW Core IG v1.0.0 compliance — 9/9 profiles validated
• Built-in FHIR browser — GET /ui for CRUD without writing code
• One-command deployment — bash scripts/setup.sh
• SMART on FHIR — JWT bearer authentication (opt-in)
