The portal's own schema, as data: one row per column of every dataset, with its type and definition. The machine-readable answer to what is in the Atlas.
Generated from the dataset registry itself, so it can never drift from the real schema. Feed it to a script, a notebook, or a model to orient before querying.
| Column | Type | Definition |
|---|---|---|
| dataset_slug | text | Slug of the dataset; its download URL is /api/datasets/<slug>. |
| dataset_title | text | Display title of the dataset. |
| category | enum | argument-graph, signals, evidence, sources, research, scout, scan, intel, tooling, or meta. |
| column_key | text | Machine name of the column; the CSV header. |
| column_label | text | Display name of the column. |
| column_type | enum | text, number, date, enum, or longtext. |
| column_def | text | One-line gloss of what the column holds. |
