FHIR Resources

FHIR Resources and Searches

The runtime serializes FHIR R4 (4.0.1) resources with HAPI FHIR.

Supported Export Types

• Patient
• Condition
• AllergyIntolerance
• MedicationRequest
• MedicationStatement
• Observation
• Procedure
• Provenance

These types are also the default _type set when _type is omitted.

Mock Search Parameters

Resource	Parameters
Patient	gender, birthdate, supported _has, _id, _elements=id, _summary=count
Condition	code, subject, date, _summary=count
Observation	code, subject, patient, date, _summary=count
MedicationRequest	code, subject, patient, date, _summary=count
MedicationStatement	code, subject, patient, date, _summary=count
Procedure	code, subject, patient, date, _summary=count
AllergyIntolerance	code, patient, date, _summary=count
Provenance	date, target, _summary=count

Unsupported search parameters return HTTP 400 rather than being ignored.

For adapter count searches, patient-compartment reference parameters also support standard Patient chaining, including direct criteria such as subject:Patient.gender and reverse criteria such as subject:Patient._has:Condition:subject:code. Provenance uses target:Patient.*. Verkennen always combines these chains with _summary=count, so its responses have no resource entries. _elements=id remains an ordinary supported search result parameter but is not used by Verkennen.

Primary Prototype Date Fields

Resource	Field
Patient	birthDate
Condition	onsetDateTime or recordedDate
Observation	effectiveDateTime or issued
MedicationStatement	effectiveDateTime or dateAsserted
MedicationRequest	authoredOn
Procedure	performedDateTime
AllergyIntolerance	onsetDateTime
Provenance	recorded

The implementation compares the leading ISO YYYY-MM-DD and is not a complete FHIR search engine.
