Fieldset

Changelog — Fieldset Spec 1.0 ​

Editorial — 2026-10-22 (no version change) ​

  • The README states the meta-schema's SHA-256 and advises validators to bundle meta-schema.json rather than fetch its $id at runtime; the docs site serves the file at the $id URL. No semantic change: specVersion stays 1.0.0 and the meta-schema is unchanged.

Rename — 2026-10-21 (no version change) ​

  • Renamed from "Form Schema Spec 1.0" to "Fieldset Spec 1.0". The meta-schema $id is now https://beyerenrico.github.io/fieldset/spec/form-definition/1.0/meta-schema.json (was https://localhost/spec/form-definition/1.0/meta-schema.json); the bundled template registry is urn:fieldset:bundled-templates. No semantic change: specVersion stays 1.0.0, $schema and source.registry remain pattern-only, so definitions naming the former URIs stay valid.

1.0.0 — 2026-10-16 ​

  • Initial release: definition structure, 30 element types, JsonLogic dialect with decimal and date operators, evaluation algorithm, validation error codes, lint rules, versioning and checksum rules.
  • Reserved for later features: role (with roles.json), source, i18n, the record type.
  • Documented extension: x-import.
  • Clarified (same day, before any release): round stability, incremental visibility, normalization errors, repeater minItems on empty lists, rating/attachment/signature/location/hidden checks, JS Number() and == array rules, variadic min/max, operator error handling, lint path and reference rules, data-contract time pattern.
  • Hardened (M1 review, before release): restricted ECMAScript pattern subset with fixed semantics and no nested quantifiers (§3.4), 4,096-code-point pattern subject limit, 60-digit decimal limit, 512-level nesting limit and logic_too_deep, calculation order (topological, document order for ties), 254-code-point email limit, finite location numbers, explicit check order, meta-schema URI pattern instead of format: uri, strict asset UUIDs.
