# Dataset metadata

There are a variety of metadata associated with datasets recorded with Kernel's systems. This includes unalterable details such as the time, date, and duration of each dataset recording, the hardware system used, the researcher who created the dataset, and so forth. There are also metadata that are editable; some that must conform to specific data sets or formats, and some that are fully customizable.

- Metadata that are customizable can be edited.
- Metadata can be used to search for a specific session or set of datasets.
- Metadata can be downloaded for an individual dataset.
- Metadata can be downloaded for a group of datasets associated with a Study or Participant ID.

Each dataset contains the following metadata fields:

| **Dataset ID** | Not Editable | Auto-generated unique value |
| --- | --- | --- |
| **Participant ID** | Not Editable | Participant ID corresponding to the participant |
| **Researcher** | Not Editable | User ID of Researcher logged into Portal during the session. |
| **Dataset Start Time** | Not Editable | Year/month/day/hour/minute/second/100th of a second |
| **Duration** | Not Editable | Casual description (minutes, seconds) |
| **Data Streams** | Not Editable | Name of Flow headset |
