Versioning and conformance
§8.1 Versioning
- SemVer for the spec;
versionin every envelope; supported versions span ≤ 2 MAJORs; producers get 180 days on MAJOR bumps; deprecated terms warn for one release, then error. - A release candidate becomes normative only after ≥ 1 publisher ships it publicly — the spec never outruns its implementers.
§8.2 Profiles
Core: the manifest + one conformingplacesfeed with the required field set.Extended: capacity, needs, hours, media, institutional contact.- Editorial rule: a MUST that a script cannot validate SHOULD be a SHOULD.
§8.3 Conformance is measured
Conformance = passing the published validator, never self-declaration
(production evidence: adapter registries that declare unimplemented
capabilities — manifests lie, behavior doesn’t). Registry badges are
re-measured on schedule; states: conforming | stale (validator passing
but last_updated beyond 7 × ttl) | failing | unreachable |
archived.
§8.4 Extensibility
Unknown members MUST be preserved and MUST NOT fail validation;
x_{publisher}_{field} namespaced extensions are always allowed; shared
extension sets become versioned Profiles at public URIs.
§8.5 Reserved for v0.2 (recorded so names don’t drift)
- Entities:
need/offer(withquantity_requiredandquantity_covered— the field that prevents over-delivery to saturated points while unserved zones wait),rental_notice,damage_report(EDAN-referenced). - Alerts reference CAP — officially adopted in Colombia (IDEAM/UNGRD) — rather than any invented format; the registry records publishers’ CAP endpoints as first-class.
- The curated place index (§5.2).
