## Data Formats

Every motion is provided in three skeletal representations supporting two character models: [SOMA](https://github.com/NVlabs/SOMA-X) and Unitree G1 robot. SOMA is a canonical body topology and rig that acts as a universal pivot for parametric human body models.

### SOMA Proportional (BVH)

A per-actor skeleton that preserves the original performer's body proportions. Each actor has an individual shape file.

```
soma_proportional/bvh/{date}/{motion_name}.bvh
soma_shapes/soma_proportion_fit_mhr_params/{actor_id}.npz
```

### SOMA Uniform (BVH)

A standardized skeleton shared across all motions, enabling direct comparison and batch processing. Each motion file is paired with a single shared shape file. The base skeleton definition is provided in both BVH and USD formats.

```
soma_uniform/bvh/{date}/{motion_name}.bvh
soma_shapes/soma_base_fit_mhr_params.npz
soma_shapes/soma_base_rig/soma_base_skel_minimal.bvh
soma_shapes/soma_base_rig/soma_base_skel_minimal.usd
```

### Unitree G1 MuJoCo-compatible (CSV)

Joint-angle trajectories retargeted to the Unitree G1 humanoid robot.

```
g1/csv/{date}/{motion_name}.csv
```

## Annotations

Each motion in BONES-SEED comes with rich multimodal annotations designed for language-conditioned policy learning, motion retrieval, and motion generation.

### Natural Language Descriptions

Every motion includes up to **6 natural language descriptions** at varying levels of detail:

- **Natural descriptions (4):** Fluent, human-written descriptions from different perspectives
- **Technical description (1):** Precise biomechanical description of the motion
- **Short descriptions (2):** Concise labels for indexing and retrieval

**Example — `read_newspaper_sitting`:**

| Field | Text |
|---|---|
| `content_natural_desc_1` | character reading newspaper while sitting |
| `content_natural_desc_2` | person reads a newspaper while sitting |
| `content_natural_desc_3` | individual sits and reads a newspaper |
| `content_natural_desc_4` | A person sitting reads a newspaper, holding it with both hands, moving pages and folding the newspaper. |
| `content_technical_description` | reading a newspaper holding it with both hands while sitting, moving pages folding a newspaper |
| `content_short_description` | reading newspaper sitting |

### Temporal Segmentation Labels

Each motion includes temporal segmentation that breaks the full sequence into meaningful phases with precise timestamps and natural language descriptions. These labels were created by NVIDIA for the [Kimodo](https://research.nvidia.com/labs/sil/projects/kimodo/) project and are stored in `metadata/seed_metadata_v002_temporal_labels.jsonl` (one JSON object per line).

**Schema:**

| Field | Type | Description |
|---|---|---|
| `filename` | string | Motion filename (matches `filename` column in metadata) |
| `num_events` | int | Number of temporal segments |
| `events` | array | Ordered list of temporal segments |
| `events[].start_time` | float | Segment start time in seconds |
| `events[].end_time` | float | Segment end time in seconds |
| `events[].description` | string | Natural language description of the segment |

**Example — `inside_door_knob_left_side_open_R_002__A512`:**

```json
{
  "filename": "inside_door_knob_left_side_open_R_002__A512",
  "num_events": 3,
  "events": [
    {"start_time": 0.0, "end_time": 1.88, "description": "A person rotates the door knob with their right hand."},
    {"start_time": 1.88, "end_time": 3.53, "description": "A person opens the door outward from the inside, holding the knob and then lowers their hand."},
    {"start_time": 3.53, "end_time": 4.83, "description": "A person is standing idle and slightly moving their right hand."}
  ]
}
```

**Loading temporal labels:**

```python
import json

temporal_labels = {}
with open("metadata/seed_metadata_v002_temporal_labels.jsonl") as f:
    for line in f:
        entry = json.loads(line)
        temporal_labels[entry["filename"]] = entry["events"]

# Look up segments for a specific motion
events = temporal_labels["inside_door_knob_left_side_open_R_002__A512"]
for event in events:
    print(f"[{event['start_time']:.2f}s - {event['end_time']:.2f}s] {event['description']}")
```

### Motion Properties

Each motion is tagged with structured metadata for filtering and analysis:

| Field | Description | Example Values |
|---|---|---|
| `content_type_of_movement` | Primary movement type | walking, jogging, gesture, dancing, jumping |
| `content_body_position` | Starting/primary body position | standing, sitting on floor, crouching, crawling |
| `content_uniform_style` | Performance style | neutral, injured leg, injured torso, hurry, old |
| `content_horizontal_move` | Horizontal displacement flag | 0 or 1 |
| `content_vertical_move` | Vertical displacement flag | 0 or 1 |
