//! Canonical URLs published by the SQL on FHIR implementation guide.
//!
//! Edition 3 (`3.0.0-ballot`) moved the guide to HL7 stewardship, and a change
//! of stewardship reissues every canonical URL it publishes. The base changed
//! from `https://sql-on-fhir.org/ig` to [`IG_CANONICAL_BASE`], and the package
//! identifier from `org.sql-on-fhir.ig` to `hl7.fhir.uv.sql-on-fhir`.
//!
//! ViewDefinition is the one exception. It became an *additional resource*
//! rather than a logical model, so it carries a canonical in the **core FHIR**
//! namespace ([`VIEW_DEFINITION_STRUCTURE_DEFINITION`]) following the
//! convention for a resource incubated outside core — not one under this
//! guide's base.
//!
//! The 2.0.0-era URLs are kept alongside as `LEGACY_*` so resources authored
//! against the previous release still parse. Version 2.0.0 remains published at
//! its original canonical, and the two releases install side by side, so a
//! reader accepting both is correct against either.
/// Canonical base for every artifact this guide publishes, except
/// ViewDefinition itself.
