Each WebDataset sample contains a `.json` metadata member plus available multimodal files for that sample.
## Per-Sample JSON in Shards
The shard-local `.json` member records source id, split, gesture label when available, and `available_files`. The public manifest adds release-level source and license fields.
## Public Manifest Fields
```json
{
"manus_sample_id": "v2_test_grabbing_00000001",
"config": "hagrid_v2",
"split": "test",
"source_dataset": "HaGRIDv2",
"source_version": "HaGRIDv2",
"source_split": "test",
"source_image_id": "grabbing_00000001",
"source_license_id": "hagrid-specific-cc-by-sa-4.0-variant",
"source_license_name": "HaGRID-specific Creative Commons Attribution-ShareAlike 4.0 variant",
"contains_source_pixels": true,
"processing_pipeline_version": "manus-hagrid-v1.0",
"available_modalities": ["full_rgb", "full_depth", "hand_rgb", "hand_depth", "mesh_front"]
}
```
## Modalities
- `full_rgb.png`: full-scene RGB image.
- `full_depth.png`: full-scene depth map.
- `hand_rgb.png`: hand-region RGB crop, when available.
- `hand_depth.png`: hand-region depth crop.
- `hand_bbox.json` / `hand_depth_bbox.json`: crop bounding boxes.
- `bbox.json`, `normal.json`, `normal_oop.json`: available source annotations.
- `vertices.json`: hand mesh vertices or related mesh metadata.
- `mesh_front.png`, `mesh_back.png`, `mesh_left.png`, `mesh_right.png`, `mesh_top.png`, `mesh_bottom.png`: canonical mesh renderings where available.
- `six_view_bbox_*.json`, `extra_view_image_*`, `extra_view_bbox_*`: additional view metadata where available.
Use `available_files` in each sample and `available_modalities` in the manifest to handle split-specific missing modalities.
