##### Example
Here is an example of the `Piscine Go` settings. It presents the settings of the object attributes `Piscine Go`, the settings of one of its child which is an event and the settings of the child object attributes itself.
> NB : this object settings are provided in the admin, in the curses section: 'Piscine Go' and in the exams section 'Exam 01'.
**Piscine Go**
*Object attributes*
```json
{
"capacity": 400,
"eventDuration": 37440,
"registrationDuration": 43200,
"eventStartDelay": 240
}
```
This piscine object attributes look like this:
*Children*
> In the `Piscine Go`, children of type *exam* and *rush* have events itself.
> A **startAfter** key has to be defined for each of them, in their parent object `Piscine Go`. For example, the exam-01 gets this key:
```json
{
"startAfter": 400
}
```
This child attributes look like this:
**Exam 01**
> The object `Exam 01`, which is a child of `Piscine Go`, has its own *Object Attributes* filled in the child object.
*Object attributes*
```json
{
"eventDuration": 240,
"registrationDuration": 2160,
"eventStartDelay": 60
}
```
> NB: the **capacity** attribute is herited from the parent object `Piscine Go` here.
