Terminology Server
TIMS hosts a FHIR server that provides a unique set of ontologies/terminologies/vocabularies, with unique features such as text search and SSSOM-formatted mappings.
Notable features
- Content: CodeSystem and ConceptMap resources (see more below), and ValueSets (in development).
- CodeSystem operations: $subsumes, $lookup
- ConceptMap operations: $closure (in development)
- ValueSet operations: $expand, $validate-code (in development)
Unique offerings
The TIMS server has a few unique features, some of which are not available on any other terminology server:
- Text search of concepts (in development)
- Biomedical ontologies as CodeSystems
- SSSOM extensions for ConceptMap resources
Terminology content
CodeSystems TIMS hosts several popular biomedical terminologies, but is unique in that it offers several biomedical ontologies in the FHIR CodeSystem format, including:
- ICD10CM
- RxNorm
- SNOMED-CT
- Mondo
- HPO
- CompLOINC
- OMOP vocabularies

ConceptMap
Many of the terminologies and ontologies also contain mappings to other terminologies/ontologies, and are represented
as FHIR ConceptMap resources. TIMS uniquely includes additional fields from the SSSOM extensions (Simple Standard fo Sharing Ontology Mappings) standard,
embedded as FHIR extensions.
