Datasets are object-typed with one property per column. Prefer this
over a bare `dict` so editors and type checkers can catch malformed
schemas; a plain dict of the same shape is still accepted at runtime.

## Attributes

| Prop | Type | Default | Description |
| - | - | - | - |
| `type?` | `Literal['object']` | - | |
| `properties?` | `Dict[str, DatasetSchemaProperty]` | - | |
