# metmuseum/openaccess-embeddings-siglip2-oembeddings

Embeddings produced by **google/siglip2-so400m-patch14-384** over [`metmuseum/openaccess`](https://huggingface.co/datasets/metmuseum/openaccess), shaped to match the
[`go-embeddingsdb`](https://github.com/sfomuseum/go-embeddingsdb) `Record`
struct (with the [OEmbeddings spec](https://github.com/sfomuseum/go-embeddingsdb#oembeddings)
inside `attributes`).

| Column | Type | Notes |
|--------|------|-------|
| `provider` | string | `"metmuseum"` |
| `subject_id` | string | `metmuseum:{objectID}` — the artwork |
| `depiction_id` | string | `metmuseum:{objectID}:primaryImage` — the image |
| `model` | string | HF model id |
| `embeddings` | list<float32> | L2-normalised, dim = 1152 |
| `created` | int64 | Unix epoch seconds when this batch was generated |
| `attributes` | map<string, string> | OEmbeddings spec fields (see below) |

## `attributes` struct

| Field | Required | Source |
|-------|----------|--------|
| `type` | yes | always `"image"` |
| `preview` | yes (URI) | `primaryImageSmall` or `primaryImage` |
| `subject_url` | yes | `objectURL` (the metmuseum.org page) |
| `subject_title` | yes | `Title` |
| `subject_creditline` | yes | `creditLine` |
| `provider_name` | yes | `"The Metropolitan Museum of Art"` |
| `provider_url` | yes | `https://www.metmuseum.org/` |
| `depiction_url` | optional | `primaryImage` |

## Loading

```python
from datasets import load_dataset

ds = load_dataset("metmuseum/openaccess-embeddings-siglip2-oembeddings", split="train")
row = ds[0]
print(row["subject_id"], row["model"], row["attributes"]["subject_title"])
```
