dhd-thesaurus

The DHD Diagnosethesaurus and Verrichtingenthesaurus deliveries.

Reads a DHD thesaurus delivery in the "Uitleverformaat 5.0" (a set of UTF-8 CSV tables) into typed rows: the concepts with their flags and validity dates, the terms by type and language, and the mappings to SNOMED CT and LOINC. The crate ships no DHD content; a deployment brings its own licensed delivery.

Where it sits

dhd-thesaurus is one crate of FerroTERM, a pure-Rust FHIR terminology server for SNOMED CT, LOINC, and other clinical code systems. The crates are published so other projects can reuse them; the API is pre-1.0 and moves with the FerroTERM release train. Documentation: https://docs.rs/dhd-thesaurus.
