# Concept Reactivation

The reactivation of concepts is supported in Snow Owl via the status menu of the Concept Editor's Overview Page.

![Context Menu for Concept Reactivation](/files/sIKDdTNqbharKOV1QZnf)

During the concept reactivation process:

* the concept will become active;
* the following components will be removed/inactivated automatically:
  * Concept inactivation indicator Reference Set member;
  * Description inactivation indicator Reference Set member; and
  * Association Reference Set (SAME AS, REPLACED BY, etc.) member.

**Descriptions**: When a concept is inactivated, its descriptions remain active and receive the description non-current indicator. Those references in the Description inactivation indicator Reference Set are automatically removed/retired during the concept re-activation process.

**Relationships**: The reactivated concept must be rewired into the SNOMED hierarchy, users may add new relationships on the concept Overview Page or reactive existing inactive relationships.

Reactivating relationships is available via the Source relationships Page by clicking on the status field and selecting from the drop-down menu:

To reactivate a destination relationship, go to the Destination relationship Page, open the origin concept by double-clicking on it, and then proceed to reactivate it on the Source Relationship Page of the origin concept.

## 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/concept-editing/concept-reactivation.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.
