# Struct Base Event

> Common ATOF identity, propagation, timing, and application payload fields.

<pre />

Common ATOF identity, propagation, timing, and application payload fields.

## Fields

### `atof_version: String`

ATOF's own version, independent of the transport contract.

### `parent_uuid: Option<String>`

UUID of the parent scope, if any.

### `propagation_root_uuid: Option<String>`

Stable causal root imported or resolved when the event was emitted.

### `propagation_parent_uuid: Option<String>`

Parent imported through propagation context. The runtime uses this field to distinguish imported parents from Relay-created parents. It does not change the ATOF wire format.

### `propagation_traceparent: Option<String>`

W3C traceparent imported or derived from the local parent. Runtime-only.

### `propagation_tracestate: Option<String>`

W3C tracestate imported or inherited from the local parent. Runtime-only.

### `uuid: String`

Unique identifier for the event or span.

### `time: Option<Timestamp>`

Event timestamp in UTC.

### `name: String`

Human-readable event name.

### `data: Option<JsonValue>`

Application-defined payload.

### `data_schema: Option<DataSchema>`

Optional schema identifier for `data`.

### `metadata: Option<JsonValue>`

Optional tracing/correlation metadata.

## Implementations
