# Centralizing UN/EDIFACT metadata

The UN/EDIFACT wizard helps you create a schema to be used for the tExtractEDIField component to read and extract data from UN/EDIFACT message files.

This feature is not shipped with Talend Studio by default. You need to install it using the Feature Manager. For more information, see [Installing features using the Feature Manager](https://help.qlik.com/talend/r/en-US/8.0/studio-user-guide/install-features-to-talend-studio).
