Form.io JSON schema reference — the shapes of projects, forms and resources, and submissions. Use when constructing, editing, or interpreting Form.io JSON: form definitions from `form_get` / `form_create` / `form_update`, components (textfield, select, datagrid, panel), wizards, conditional logic, validation, submission bodies (`data`, `access`, `metadata`), and project templates for `project_import` / `project_export`. Not for: REST endpoints (see `formio-api`); server-side actions…

Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.

What the file says

# Form.io JSON Schema

This skill describes the JSON schemas for the three Form.io document types whose shape is non-trivial — projects, forms (and resources), and submissions. Action configs live in the `formio-actions` skill; role objects are simple enough to use directly from the `formio-api` reference. Use this skill to construct new JSON payloads, interpret existing ones, or author changes to them. Writing a change into a saved form runs through `formio-form-builder`'s edit lane, which shows the change and asks before `form_update` writes it.

Detail is split across reference files under `references/<domain>/`. Read only the files you need for the task at hand — the overview below is usually enough to orient yourself; load a reference file when you need a specific property list.

How to install

The exact contents, by fingerprint

mdr add formio/ai/formio-schema@sha256:c5358f8494b5f829

The line at the top of this page pins the label git:20261030.a714871, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
