Search Domains
STAGE 1 of 3 (Discover). Search published Jargon Domains by name, description, definitions, release notes, and model content. Returns a ranked shortlist only — not enough detail to evaluate fit or build from. For each promising result, call get_domain_definition (STAGE 2) next to evaluate whether it's the right domain before using it. Next step: call get_domain_definition(domainRelease) to evaluate this candidate.
Get authored Domain definition
STAGE 2 of 3 (Evaluate). Get the complete human-authored definition of one immutable, published Jargon Domain release — its information model, definitions, mappings, code tables, lifecycle definitions, and other authored semantic content. This is the architect's source definition, BEFORE compiler resolution: import references (e.g. 'schema.Thing.name') and DSL shorthand are NOT expanded here. Use this to decide whether a shortlisted domain is the right fit — its field names, definitions, and cov
Get resolved domain
STAGE 3 of 3 (Implement). Get Jargon's authoritative compiler-resolved semantic model for one immutable, published Domain release: resolved imports, concrete types, inheritance, ownership, and constraints. This is the ONLY output suitable for generating schemas, types, or code from — prefer it over inferring types or resolving imports independently from get_domain_definition's output.
