| # Bpl Cards |
|
|
| Catalogue metadata extracted from digitised material with a multimodal model and |
| human-reviewed. |
|
|
| ## Schema |
|
|
| | Field | Type | Description | |
| | --- | --- | --- | |
| | `call_number` | `string` | | |
| | `heading` | `string` | | |
| | `author` | `string` | | |
| | `title` | `string` | | |
| | `imprint` | `string` | | |
| | `collation` | `string` | | |
| | `notes` | `string` | | |
| | `tracings` | `string` | | |
|
|
| The exact machine-readable output schema (enum values, nested objects, optionality) |
| is in [`schema.json`](schema.json) — the `response_format` the labels follow. |
|
|
| ## How it was labelled |
|
|
| - **Model:** `Qwen/Qwen3-VL-30B-A3B-Instruct` |
| - **Prompt hash:** `6993b107dd8d` |
| - **Schema version:** `v1` |
| - **Review:** each item was shown to a human reviewer who gave a verdict and an |
| optional free-text note. **Gold labels are the 2 items a human signed |
| off:** 2 _verified_ (model output a reviewer marked good enough) and |
| 0 _corrected_ (a reviewer edited the fields into the right answer). |
| Each row's `_label_status` (`verified` / `corrected`) and, for corrected rows, |
| `_corrected_fields` record which is which. |
| - **Model baseline (for benchmarking — not the label quality):** the labels above are |
| fully human-verified, so this figure describes the *generating* model, not the |
| dataset. It agreed with reviewers on **70.0%** of 5 |
| scored items (good_enough=2, |
| needs_tweaks=3, |
| not_accurate=0; needs_tweaks scored as half credit) — |
| a reference point for scoring other models against this set. |

| <details> |
| <summary>Extraction prompt</summary> |
|
|
| ``` |
| You are reading a catalogue card from the Boston Public Library's Rare Books |
| Department. Look at the image and return a single JSON object matching the |
| schema. Emit JSON only — no commentary or markdown. |
| |
| - `call_number`: the shelfmark, usually printed down the left-hand edge. |
| - `heading`: the subject or added heading, usually typed in capitals across the |
| top of the card. Leave it null when the card has none. |
| - `author`: the main entry — the personal or corporate name the card files |
| under, transcribed as printed, including dates. |
| - `title`: the title of the work. |
| - `imprint`: place, publisher and date of publication. |
| - `collation`: the physical description — pagination, illustrations, size. |
| - `notes`: anything else the card records, such as a contents list. |
| |
| - `tracings`: the numbered list of added entries at the foot of the card. |
| Transcribe it as printed. Null if the card has none. |
| |
| Transcribe as printed and never add markup. Use null for anything the card does |
| not carry — never infer a `heading` from the title. |
| ``` |

|
| ## Provenance |
|
|
| Produced by paratext. Each row carries `_label_status`, `_verdict`, |
| `_prompt_hash`, `_schema_version`, `_round`, `_model`, and the reviewer's |
| `_review_note` (plus `_corrected_fields` on corrected rows). |
|
|
| ## Rights & license |
|
|
| No licence set (front matter records `license: other`). **CC0-1.0** is recommended for open sharing — pass `--license`/`--rights` to `paratext export` or set them under `[project.<name>.export]`. |
|
|
| ## Limitations |
|
|
| Single-institution scope; labels reflect one model + prompt at a point in time and |
| the reviewing institution's cataloguing conventions. |
