## Dataset Structure

The dataset is organized into the following structure:

```
|-- subdataset1

|   |-- raw_data  # Original data files
|   |-- time_series # Rule-based Imputed data files
|   |   |-- all_version_1.parquet # Time series data for each subject can be multivariate, can be in csv, parquet, etc.
|   |   |-- all_version_2.parquet
|   |   |-- ...
|   |   |-- id_info.json # Metadata for each subject

|   |-- weather
|   |   |-- location_1
|   |   |   |-- raw_data
|   |   |   |   |-- daily_weather_raw_????.json
|   |   |   |   |-- ...
|   |   |   |   |-- daily_weather_????.csv
|   |   |   |   |-- ...
|   |   |   |   |-- hourly_weather_????.csv
|   |   |   |   |-- ...
|   |   |   |-- weather_report (can be flattened and use regex to extract the version)
|   |   |   |   |-- version_1
|   |   |   |   |   |-- xxx_weather_report_????.json
|   |   |   |   |   |-- ...
|   |   |   |   |-- version_2
|   |   |   |   |-- ...
|   |   |   |-- report_embedding # embedding for the weather report
|   |   |   |   |-- version_1

```

## id_info.json Structure

The `id_info.json` file contains metadata for each subject in the dataset. Extracted from the raw dataset. The structure is as follows:

```json
{
    "id_1": {
        "len": 1000, # Length of the time series data
        "sensor_downtime": {
            1: {
                "time": [yyyy-mm-dd hh:mm:ss, yyyy-mm-dd hh:mm:ss],
                "index": [start_index, end_index]
            },
            2: {
                "time": [yyyy-mm-dd hh:mm:ss, yyyy-mm-dd hh:mm:ss],
                "index": [start_index, end_index]
            },
            ...
        },
        "other_info_1": "value_1", # Other information about the subject customizable entry
        "other_info_2": "value_2",
        ...
    },
    "id_2": ...

}
```

## static_info.json Structure

The `static_info.json` file contains static information for the whole dataset. The structure is as follows:

```json
{
    "general_info": "description of the dataset",
    "downtime_prompt": "",
    "channel_info": {
        "id_1": {
            "channel_1": "channel 1 is xxx",
            "channel_2": "channel 2 is xxx"
        },
        "id_2": {
            "channel_1": "channel 1 is xxx",
            "channel_2": "channel 2 is xxx"
        },
        ...
    },
}
