This page holds the JSON Schema for `infobox: type: dataset`, used by data source pages (the star catalogue, the known black hole list) (the field list follows SCIENCE_CORPUS 3.2 Reference). Every page whose frontmatter names this type is validated against it on save: a schema error blocks a save by a new account or an API client and warns a trusted editor.

Values are flexible so that writers can record what the sources allow. A field may be plain text or a number, a quantity object `{value, unit, min, max, error, source, note}`, or a by-status mapping `{observed, model, sim}` when the measured, inferred and generated values differ. Fields not listed here are allowed and shown under "Other" in the infobox. The `x-pax` block carries display metadata: the groups in order, each group's default provenance tag, and the label and unit for every field.
