# 6. Archiver un champ
Lorsqu’un champ ne doit plus être utilisé, il peut être **archivé**.
L’archivage permet de retirer un champ de l’usage courant sans le supprimer définitivement de la base.
Un champ archivé :
* n’apparaît plus dans la liste active du socle de base,
* n’est plus proposé dans les nouveaux usages ou formulaires,
* mais reste conservé dans le système.
L’archivage n’efface pas les données déjà associées à ce champ.\
Les informations existantes restent donc disponibles dans les dossiers ou formulaires où ce champ a déjà été utilisé.
Cette logique permet de préserver la cohérence des données historiques tout en retirant le champ des usages futurs.\

## 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://guides.data.gouv.fr/passe-marche/socle-de-base/6.-archiver-un-champ.md?ask=&goal=
```
`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.
