#### Dataset Card for dwb2023/crisis_prediction_edges

**Purpose**  
Stores the edges (relationships) between nodes in the crisis prediction graph, representing connections like routes, impacts, and dependencies.

**Schema Description**
| Field Name | Data Type | Description |
|------------|-----------|-------------|
| source_node_id | string | ID of the source node |
| target_node_id | string | ID of the target node |
| relationship_type | string | Type of relationship (e.g., "IMPACTS", "ROUTED_THROUGH") |
| properties_json | string | JSON string containing edge properties |
| valid_from | timestamp[ms] | When the relationship became valid |
| valid_to | timestamp[ms] | When the relationship expired/will expire |
| created_at | timestamp[ms] | When the edge was created |

**Example Entry**
```python
{
    "source_node_id": "HKG_AIRPORT",
    "target_node_id": "FRA_AIRPORT",
    "relationship_type": "ROUTED_THROUGH",
    "properties_json": {"capacity": "500t", "frequency": "daily"},
    "valid_from": 1706745600000,
    "valid_to": 1709251200000,
    "created_at": 1706745600000
