+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.

-Real footage can't put a vessel at exactly 7 NM, hold the visibility constant, or show you the same ship from eight aspects. `seascape` renders maritime scenes where you choose all of that, and tells you exactly where everything was.
+## Fields
 
-## Highlights
+| 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 |
 
-- **Ground truth by construction.** Camera extrinsics and intrinsics are known rather than estimated. Every frame comes with each target's box, range and bearing, and the horizon. In an 8-bit frame, a target too faint to tell from its surroundings gets no box ([outputs](docs/outputs.md)).
-- **LWIR as well as EO.** Measured seawater optical constants, a skin and foam that radiate differently from the bulk, a band-integrated sky whose clouds reflect in the sea, hulls whose parts each settle at their own heat balance, and a microbolometer model ([primer](docs/primer/README.md)).
-- **Multi-sensor rigs.** Several cameras, each with its own resolution, optics and band, in one scene.
-- **Sequences.** Targets under way, ownship roll, pitch and heave, seamless loops, mp4.
+`schema.json` is the authority; a row that fails it is not added.
 
-> [!NOTE]
-> LWIR is good enough to look at and to regression-test against, but not a radiometric reference: shadowing between unresolved wave facets is not modelled, and the sea mirrors no hulls. A detection-range or contrast figure taken off a render needs review before anyone acts on it.
+## Adding an asset
 
-## Install
+No clone needed: fetch the small files, add the asset, upload only what changed.
 
 ```bash
-git clone https://github.com/SEA-AI/seascape.git
-cd seascape
-uv sync
+hf download SEA-AI/seashapes --repo-type dataset --local-dir seashapes --exclude "*.glb" --exclude "*.png"
+cd seashapes
 ```
 
-Blender ships as a Python package, so there is nothing else to install.
-
-## Quickstart
+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
-uv run seascape render scenarios/baseline.toml -o out/
-```
-
-```text
-out/
-├── bow_eo.jpg
-├── bow_ir.jpg
-├── calibration.json
-├── labels.json
-└── blender.log
+hf upload SEA-AI/seashapes . . --repo-type dataset --include "<id>/*" --include metadata.jsonl --commit-message "Add <id>"
 ```
 
-`seascape build` writes the `.blend` instead, to open in Blender.
-
-A scenario is a TOML file, and `extends` makes a variant a diff:
+Pin the new commit, never `main`, wherever the asset is used.
 
-```toml
-extends = "baseline.toml"
+## Licences
 
-[sky]
-hdri = "belfast_sunset"
-
-[[objects]]
-asset = "lateral_mark"
-range_m = 100.0
-bearing_deg = -6.0
-```
-
-<details>
-<summary>Tab completion</summary>
+| Files | Licence |
+|---|---|
+| `<id>/<id>.glb` | The author's, given per row in `metadata.jsonl`; an Apache-2.0 model has its licence text beside it, `<id>/LICENSE` |
+| `<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 |
 
-With `seascape` on the `PATH`, add to `~/.zshrc`:
+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`:
 
-```bash
-eval "$(_SEASCAPE_COMPLETE=zsh_source seascape)"
+```sql
+SELECT title, author, source_url, licence
+FROM 'hf://datasets/SEA-AI/seashapes/metadata.jsonl';
 ```
 
-For bash, `bash_source` in `~/.bashrc`.

+      result of this License or out of the use or inability to use the
+      Work (including but not limited to damages for loss of goodwill,
+      work stoppage, computer failure or malfunction, or any and all
+      other commercial damages or losses), even if such Contributor
+      has been advised of the possibility of such damages.
+
+   9. Accepting Warranty or Additional Liability. While redistributing
+      the Work or Derivative Works thereof, You may choose to offer,
+      and charge a fee for, acceptance of support, warranty, indemnity,
+      or other liability obligations and/or rights consistent with this
+      License. However, in accepting such obligations, You may act only
+      on Your own behalf and on Your sole responsibility, not on behalf

+The STLs are CAD/OpenSCAD in github.com/IEAWindTask37/IEA-15-240-RWT.
+
+- Parts are the STL's loose parts: structure (monopile or floater with tower),
+  nacelle, hub and three blades.
+- Rotor: hub and blades under an empty `<id>_rotor` at the hub, its local +Y the
+  shaft pointing upwind, normal to the plane of the blade tips.
+- The rotor faces glTF -Z (Blender +Y).
+- Paint: RAL 7035 light grey; RAL 1023 traffic yellow below +15 m, the transition
+  piece or the platform's freeboard (IALA O-139: yellow from HAT to 15 m).
+- A monopile goes on to the IEA design's 30 m seabed (Gaertner et al. 2020).
