JSON Schema - Recursive Schema Definition

I have a JSON Schema

{
'description': 'TPNode',
'type': 'object',
'id': 'tp_node',
'properties': {
'selector': {
'type': 'string',
'required': true
},
'attributes': {
'type': 'array',
'items': {
'name': 'string',
'value': 'string'
}
},
'children': {
'type': 'array',
'items': {
'type': 'object',
'$ref': '#'
}
},
'events': {
'type': 'array',
'items': {
'type': 'object',
'properties': {
'type': {
'type': 'string'
},
'handler': {
'type': 'object'
},
'dependencies': {
'type': 'array',
'items': {
'type': 'string'
}
}
}
}
}
}
}


What I'm trying to express in the children property is that it's an array of objects with the same exact schema. Is this the correct way to describe it?

Use the id of the schema you need to reference

'$ref': 'tp_node'
