# Data Model Rules editor views

Navigate the Cortex XSIAM Data Model Rules editor.

{% hint style="warning" %}
Data Model Rules requires **View/Edit** RBAC permissions for **Data Management** (under **Configurations** → **Data Management**), which are the same permissions required for Dataset Management, Parsing Rules, and Event Forwarding.
{% endhint %}

The Data Model Rules editor contains the following views.

* **User Defined Rules** (default): Displays an editor for writing your own custom Data Model Rules that override the default rules. Once you edit a default Data Model mapping, you will no longer receive Marketplace updates.
* **Default Rules** (read-only): Displays the data model rules that are provided by default.
* **Both**: Side-by-side view of both the **Default Rules** and **User Defined Rules**, so that you can easily view both sets of rules on the same screen.

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

Perform an HTTP GET request on the following URL with the `ask` and `goal` query parameters:

```
GET https://cortex-docs.paloaltonetworks.com/cortex-xsiam/configure-cortex-xsiam/data-management/data-model-rules/data-model-rules-editor-views.md?ask=<question>&goal=<user_goal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is what the user is ultimately trying to achieve, the reason they need the answer. Sharing it helps GitBook give you a better, more relevant answer. A goal is most helpful when it describes the outcome the user wants rather than restating the question. For example, with `ask=how do I create an API token`, a goal like `automate deployments from our CI pipeline` lets GitBook tailor the answer to that use case.

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.
