# System Fields

System fields ("System Value") in Tabidoo are special, read-only fields that automatically capture and store system-level metadata for each record. These fields are essential for tracking changes, authorship, and lifecycle events without manual user input.

They are added via the field type **System Value**, and allow you to choose the specific type of data that should be.

### Use Cases

-   **Audit Trails**: Know who created or last edited a record and when.
-   **Automation Triggers**: Use system fields in workflows to automate based on authorship or timestamps.
-   **Debugging**: Understand when and by whom records were modified.
-   **Compliance**: Track document versioning and GDPR-compatible metadata.

### Available Types of System Fields
