# Folio smith/hmsg

Hirshhorn Museum and Sculpture Garden

- Dataset key: `smith/hmsg`
- Rows: 531

# Observed Schema

## `dto_coll_collection`

- Core: `coll`
- DTO type: `collection`
- Rows: 9

A collection / series — an aggregation of items rather than a single object.
Two producers: the "folio of folios" (each row is a whole folio) and aggregators like the
Smithsonian that expose collections and series alongside objects. Unlike a generic item, a
collection is browsed by its dataset-level descriptors — provider, country, language, size —
so those are promoted to facets here. `subjects` (a parent facet) carries the dtoType mix.
/

| Field | Type | Flags | Description |
| --- | --- | --- | --- |
| `id` | `?string` |  |  |
| `contentType` | `?string` |  |  |
| `stage` | `?string` | filterable, facet | Pipeline processing stage (raw / normalized / enriched). A facet so you can filter to enriched items; later this can be made dev-only. |
| `title` | `?string` |  | dcterms:title |
| `pageCount` | `?int` | sortable | Number of pages in the document. |
| `source` | `string` |  | Source of this data: import \| ai \| ocr \| human |

## `dto_drawing`

- Core: `obj`
- DTO type: `drawing`

DTO for drawn works: pencil, ink, charcoal, watercolour, pastel, etc.
Covers any work where drawing is the primary medium.
Subclass for more specific drawn types (CartoonDto, SketchDto, etc.)

# Query Guide

This folio stores canonical rows in `item` and observed field metadata in `schema_table` / `schema_property`.

```sql
select * from schema_table where kind = 'dto';
select * from schema_property where table_id = ? order by position;
select local_id, label, dto_type, dto_data, extras from item limit 20;
```

Convenience views are generated from observed DTO fields:

```sql
select * from dto_coll_collection limit 20;
