JamTS

v1.0 · Spring Boot · Commercial · Port 8085

JamTS is the national terminology service. It resolves the most common gap in real-world deployments: local lab codes that do not map to standard LOINC or SNOMED CT.

Operations​

$translate — local to canonical​

GET /fhir/ConceptMap/$translate?system=urn:br01.local&code=GLU&target=loinc

Response:

{
  "match": [{"concept": {"code": "1558-6", "display": "Fasting glucose [Mass/volume] in Serum or Plasma"}}]
}

$validate-code​

GET /fhir/CodeSystem/$validate-code?system=http://loinc.org&code=24748-4

$lookup​

GET /fhir/CodeSystem/$lookup?system=http://loinc.org&code=58410-2

SNOMED CT via Snowstorm​

JamTS federates to a Snowstorm SNOMED CT server for SNOMED lookup and expression constraint language queries. Configure the Snowstorm URL:

jamts:
  snowstorm-url: http://snowstorm:8080
  snowstorm-branch: MAIN/2026-01-31

Country-specific code systems​

JamTS ships with ConceptMaps for common country-specific local code systems. Additional maps can be loaded via the admin API:

POST /fhir/ConceptMap
Content-Type: application/fhir+json

{...ConceptMap resource with local-to-LOINC mappings...}
