# SeaShapes
3D models of maritime objects, each with its real-world size and its source. One folder per asset, holding the model and a preview. `metadata.jsonl` describes every asset, one row each, and `schema.json` defines the fields.
## Query
In the Data Studio SQL console, or anywhere DuckDB runs:
```sql
SELECT id, category, length_m, width_m, licence
FROM 'hf://datasets/SEA-AI/seashapes/metadata.jsonl'
WHERE list_contains(tags, 'containers') AND length_m BETWEEN 80 AND 100;
```
Pin a file by commit, never by branch:
```
https://huggingface.co/datasets/SEA-AI/seashapes/resolve/<commit>/<id>/<id>.glb
```
## Fields
| Field | Meaning |
|---|---|
| `id` | Folder name |
| `file_name` | Preview image, `<id>/preview.png` |
| `title`, `author`, `source_url`, `licence` | Attribution; `licence` is an SPDX identifier |
| `category`, `tags`, `description` | What the object is; `tags` are free filters |
| `length_m`, `width_m`, `height_m` | Real overall size, keel to top for a vessel |
| `size_source` | How the real size is known; model units are arbitrary |
| `file`, `format`, `size_bytes`, `sha256` | The file |
| `front_axis` | Where the front points in the file; omitted when it is glTF's `+z` |
| `triangles`, `textures`, `texture_max_px` | Mesh detail |
| `modified` | Whether the file differs from what the source offers |
| `added` | Date added |
`schema.json` is the authority; a row that fails it is not added.
## Adding an asset
No clone needed: fetch the small files, add the asset, upload only what changed.
```bash
hf download SEA-AI/seashapes --repo-type dataset --local-dir seashapes --exclude "*.glb" --exclude "*.png"
cd seashapes
```
1. Put the model at `<id>/<id>.glb` and append its row to `metadata.jsonl`. Leave `sha256` and `size_bytes` out; the check fills them in.
2. Render its preview: `uv run tools/preview.py <id>`.
3. Check every row: `uv run tools/validate.py`. Rows whose folder is here are checked against their files, the rest against `schema.json`.
4. Upload in one commit:
```bash
hf upload SEA-AI/seashapes . . --repo-type dataset --include "<id>/*" --include metadata.jsonl --commit-message "Add <id>"
```
Pin the new commit, never `main`, wherever the asset is used.
## Licences
| Files | Licence |
|---|---|
| `<id>/<id>.glb` | The author's, given per row in `metadata.jsonl` |
| `<id>/preview.png` | The model's licence and attribution; each is a render of the model, modified: rendered by SEA.AI |
| `metadata.jsonl`, `schema.json`, `README.md` | CC BY 4.0, SEA.AI |
| `tools/` | Apache-2.0, SEA.AI |
Credit the author and link the source when you share a model or work made from it. Every row of `metadata.jsonl` carries its `title`, `author`, `source_url` and `licence`, and models from Sketchfab embed the same in their glTF `asset.extras`:
```sql
SELECT title, author, source_url, licence
FROM 'hf://datasets/SEA-AI/seashapes/metadata.jsonl';
```
Models from Sketchfab are the GLBs it offers for download, unmodified. Their authors do not endorse SEA.AI or this dataset.
