# Automata

`Automata` shares many fields with `AtomicState`. It differs by:

* the lack of `properties.is_chat_allowed` and `tasks` fields.
* the different special event it can handle
* `initial` , `states` and `context` fields.

`Automata` (only difference)

| Field's Name             | Type (Required/Optional) | Description                                                                                                                                    | Example                              |
| ------------------------ | ------------------------ | ---------------------------------------------------------------------------------------------------------------------------------------------- | ------------------------------------ |
| type                     | "automata" (Optional)    | Indicates the type of structure, which here would be 'automata'.                                                                               | 'automata'                           |
| context                  | Object (Optional)        | These are variables that are shared among all child states. These can be of type Variable. The key should be in lowercase, snake\_case format. | { "prompt": { "type": "text" } }     |
| context\[variable\_name] | Variable (Required)      | Variable can have an initial value or just a specified type.                                                                                   | { "type": "text", value: "Welcome" } |
| initial                  | string (Required)        | This is the name of the initial state that the automata should start in.                                                                       | 'initial\_state'                     |
| states                   | Object (Required)        | This holds all available states in the automata. Each state could be an AtomicState or Automata                                                |                                      |
| transitions              | Object (Optional)        | Automata can trigger special events, including DONE.                                                                                           |                                      |
