Function: resolveSystem()

resolveSystem(id): ResolveSystemResult

Resolve a code-system identifier to its canonical SystemIdentity.

Accepts, in order of attempt: a canonical URI (case-insensitive), a v2-XXXX mnemonic or a v2 table URI/OID (resolved structurally), a bare or urn:oid:-prefixed OID, or an HL7 v2 Table 0396 mnemonic. Whitespace is trimmed. An empty or unrecognized identifier yields a typed UnknownSystem - the resolver never invents a URI.

Parameters

id

string

The identifier (canonical URI, OID, urn:oid: OID, or mnemonic).

Returns

ResolveSystemResult

The resolved SystemIdentity, or { unknown: true, input }.

Example

import { resolveSystem } from "@cosyte/terminology";

resolveSystem("2.16.840.1.113883.6.1"); // => { url: "http://loinc.org", … }
resolveSystem("SCT"); // => { url: "http://snomed.info/sct", … }
resolveSystem("http://example.com/nope"); // => { unknown: true, input: "http://example.com/nope" }
