Guides

Task-oriented recipes ("how do I X?") for @cosyte/terminology. Each guide is a short, copy-pasteable answer to one real integration question.

Status: this package ships the identity resolver, the ConceptMap $translate engine, the CodeSystem $lookup/$validate-code loaders, ValueSet $expand/binding, UCUM validation, the crosswalk resolvers, and the RxNorm drug graph.

Available now

• Canonicalize a code system: turn an OID or HL7 v2 mnemonic off a parsed message into a FHIR canonical URI with resolveSystem, handling the typed unknown case.
• Translate through a ConceptMap: loadConceptMap + translate, reading the matches (with their relationship and steward comments) or the typed unmapped outcome.
• Look up a code's display and status: $lookup / $validate-code over a BYO CodeSystem.
• Validate a code against a value set: $validate-code / $expand over a BYO ValueSet.
• Validate a UCUM unit: recognition/validation, never magnitude conversion.
• Resolve a SNOMED→ICD-10-CM crosswalk or the ICD-9↔ICD-10 GEMs: carrying every steward No-Map/advice flag, never inverted.
• Navigate the RxNorm drug graph: resolve a drug to its components and through them to its ingredient, a brand to its generic, or an NDC to its RXCUI, over a BYO RxNorm RRF release, never fabricating an edge.

The Quickstart covers the one-line calls, and the API Reference documents every shipped export.
