{
    "allOf": [
        {
            "$schema": "https://json-schema.org/draft-07/schema",
            "type": "object",
            "properties": {
                "newproperty": {
                    "type": "string"
                }
            }
        },
        {
            "$ref": "https://json.schemastore.org/package"
        }
    ]
}
