# Export & Import Decision Trees

## File Structure of JSON format

Imported & Exported files need to have some mandatory structural information:

* **name:** name of the decision tree
* **description:** description of the decision tree
* **type:** type of the decision tree
* **status:** [status of the decision tree](/doc/v1/other/rule-state.md)
* **inputSchema:** input schema of the decision tree
* **outputSchema:** output schema of the decision tree
* **nodes:** rules of the decision tree

{% hint style="warning" %}
Type: there are two types:

* "**decision-table**" - for decision tables
* **"decision-tree"** - for decision trees
* "**complex-rule**" - for scripting rules
  {% endhint %}

#### Minimal File Structure Example:

```json
{
    "name": "",
    "description": "",
    "type": "",
    "status": "",
    "inputSchema": {
    },
    "outputSchema": {
    },
    "nodes": []
}
```

#### File Structure Example:

```json

    "type": "decision-tree",
    "name": "Sample Tree",
    "description": "Sample Decision Tree description",
    "inputSchema": {

# Agent Instructions: Querying This Documentation

If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter:

```
GET https://docs.decisionrules.io/doc/v1/decision-trees/import-and-export-rule.md?ask=<question>
```

The question should be specific, self-contained, and written in natural language.
The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
