# Removing Components

There are two options for removing newly added components: Deletion or Inactivation.

* **Deletion** will permanently delete the component from the repository.  When you delete a concept, all of its descriptions, source, and destination relationships, children, and associated Reference Set members are deleted as well. You can review the list of components to be deleted in a dialog before confirming the operation. 

{% hint style="danger" %}
This operation cannot be undone.
{% endhint %}

{% hint style="info" %}
Once you create a version of a component it has an associated effective time and is considered published. Hence, it can not be deleted anymore, only inactivated.
{% endhint %}

* **Inactivation** will keep the component in the repository, with its status set to inactive.

## 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, and the optional `goal` query parameter:

```
GET https://docs.b2ihealthcare.com/snow-owl-authoring-platform/editing-and-authoring/snomed-ct-editing/removing-components.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

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.
