Generate a JSON schema for an event called `{{event-name}}`. This schema must follow FlowMart's payload standards.

**FlowMart Payload Standards:**

*   Every payload MUST include a top-level `metadata` field.
*   The `metadata` field MUST contain:
    *   `correlationId`: A string, preferably in UUID format.
    *   `createdDate`: A string in ISO 8601 format (e.g., "2023-11-02T14:29:55Z").
*   The main event details should be within a top-level `data` field.

**Example `UserSignedUp` Event Payload:**

```json
{
  "metadata": {
     "correlationId": "f47ac10b-58cc-4372-a567-0e02b2c3d479",
     "createdDate": "2023-11-02T14:29:55Z"
  },
  "data": {
    "userId": "user-789",
    "email": "test@example.com",
    "signUpMethod": "Google"
  }
}
```

**Invalid Example (Missing `metadata`):**
```json
{
  "data": {
    "userId": "user-123",
    "email": "invalid@example.com"
  }
}
```

**Invalid Example (Missing `correlationId` in `metadata`):**
```json
{
  "metadata": {
     "createdDate": "2023-11-01T10:00:00Z"
  },
  "data": {
     "userId": "user-456",
     "email": "incomplete@example.com"
  }
}
```

**Task:**

Create the JSON schema definition for the `UserSignedUp` event described above, ensuring it enforces the FlowMart payload standards.
