# Asset Library

Unified robotics and simulation asset library.

This repository stores normalized reusable assets from RoboCasa, Discoverse, TinyForge, Hunter, and third-party asset sites. It is designed to be hosted as a Hugging Face Dataset.

## Layout

Default normalized asset layout:

```text
assets/<source>/<asset_type>/<category>/<asset_id>/
```

Example:

```text
assets/robocasa/fixtures/dishwashers/Dishwasher031/
```

Collection-level imports are allowed when an upstream repository has many internal relative references:

```text
assets/<source>/<upstream_root>/
```

Current example:

```text
assets/discoverse/models/
```

Top-level repository structure:

```text

├── AGENTS.md
├── README.md

│   └── storage_spec.md
├── manifest/

│   ├── licenses.yaml
│   └── sources.yaml

```

Naming rule:

```text
<source>.<asset_type>.<category>.<upstream_id>
```

Example:

```text
robocasa.fixtures.dishwashers.Dishwasher031
```

## Current seed assets

- RoboCasa dishwasher fixtures: 25 MJCF assets under `assets/robocasa/fixtures/dishwashers/`
- RoboCasa dishwasher support files:
  - fixture registry: `assets/robocasa/fixtures/fixture_registry/dishwasher.yaml`
  - implementation reference: `docs/source_notes/robocasa/dishwasher_fixture.py`
- DISCOVERSE models collection: upstream `models/` tree under `assets/discoverse/models/`
  - stored as a collection-level asset to preserve internal relative references
  - includes MJCF, URDF, mesh, and reference image files

Placement-related notes and candidate external links are tracked in:

```text
docs/placement_asset_notes.md
docs/source_notes/third_party.md
```

## Index

The global asset index is:

```text
manifest/assets.jsonl
```

Each asset directory also contains a local `metadata.yaml`.

## Validate

```bash
python scripts/validate_asset.py assets/robocasa/fixtures/dishwashers/Dishwasher031
python scripts/validate_asset.py --all
```

Current expected result:

```text
validated_assets=26
```

## Upload to Hugging Face

Login first:

```bash
export HF_ENDPOINT=https://hf-mirror.com

```

Create the dataset repo if needed:

```bash
hf repo create <namespace>/<dataset_repo> --type dataset --private
```

Upload:

```bash
cd /path/to/asset-library
scripts/upload_to_hf.sh <namespace>/<dataset_repo>
```

## Download from Hugging Face
