SNOMED CT with FHIR
summary
SNOMED CT is presented as an ontology served by an open source Java Spring + Elasticsearch server called Snowstorm Terminology Server, available on GitHub and runnable via Docker; it exposes FHIR CodeSystem, ValueSet and ConceptMap operations (including $translate) and enforces rate limits on the public API. The demo shows Expression Constraint Language used at runtime to produce Implicit ValueSets (an ECL expansion returns 1,630 procedures then filters to 24 with a text search), code validation and subsumption checks (there are 117 diabetes subtypes), and the NormalForm property plus new concrete values enabling numeric queries like “<100 mg.”
