Terminology Service
Terminology Service
Basic Functional Requirements:
High level functional requirements for a terminology service include:
- Resolving codes into concept (descriptions)
- Resolving subsumption and other "semantic" queries between concepts
- Resolving and expanding valuesets, supporting operations between them
- Maintaining terminology systems, with provenance and versioning
- Supporting mappings between terminology systems
Integration Patterns:
- Terminology resolution as a centralized (web) service in a SOA
- Terminology as a component in a tightly coupled architecture
- Terminology as an in-memory application feature
- Hybrid combinations of the above
- High-throughput online systems, mostly focused on resolving relationships
between coded concepts and valuesets (e.g. to support semantic queries or CDS) - Low-throughput online systems, mostly focused on lookups (e.g. to support CDS authoring tools)
- Low-throughput offline systems, mostly focused on maintenance (e.g. to support maintenance tools)
Candidate Standards & Specifications:
- FHIR terminology service - HL7 FHIR TS
- CTS-2 v1.1 specification - OMG CTS-2
- Recommended TS interaction scenarios and protocols
- SNOMED-CT APIs - SnAPI [ReST]
- RxNORM APIs - RxNav [ReST]
- LOINC APIs - LOINC [ReST] [FHIR]
- UMLS APIs - UMLS [ReST]
Known Service Implementations :
- Apelon : TBD - wiki http://apelon-dts.sourceforge.net/
- 3M : both proprietary (on CTS-2 and 3M APIs) and open source (on CTS 1.2 and 3M) versions of the HDD service exist.
