Record Tags

import { getRecordTags } from "@younndai/domains";

const tags = await getRecordTags("yon.health");
// → ['VITALS', 'DX', 'RX', 'LAB', ...]

Describe Record

import { describeRecord } from "@younndai/domains";

const summary = await describeRecord("yon.health", "VITALS");
// → { tag: 'VITALS', requiredFields: ['bp'], optionalFields: ['hr', ...], fieldCount: 7 }

Required / Optional Fields

import { getRequiredFields, getOptionalFields } from "@younndai/domains";

const required = await getRequiredFields("yon.health", "VITALS"); // ['bp']
const optional = await getOptionalFields("yon.health", "VITALS"); // ['hr', 'temp_c', ...]

Sync Variants

All functions have sync variants for pre-resolved domains:

import {
  getRecordTagsSync,
  describeRecordSync,
  getBundledDomain,
} from "@younndai/domains";

const domain = getBundledDomain("yon.health")!;
const tags = getRecordTagsSync(domain);
const summary = describeRecordSync(domain, "VITALS");

Reverse Tag Lookup

Find all domains that define a given tag:

import { findDomainsByTag } from "@younndai/domains";

const result = findDomainsByTag("POSITION");
// → { tag: 'POSITION', matches: [
//     { domainId: 'yon.hr', record: {...} },
//     { domainId: 'yon.fintech', record: {...} },
//   ] }

ℹ️Note

When multiple domains define the same tag, the consumer decides which is authoritative. The parser knows from @DOC domain=, the validator receives domainId as argument.
