Therefore, in order to create any kind of object on the {{UBIK}} Android client, a legitimate parent is needed.
It is necessary to configure this possibility in the [[Application Context Management]] (ACM) using the [[UBIK Studio|UBIK Studio]]{{UBIKSTUDIO}}.You can find more information on publishing content on the mobile application in this [[How-To|How-To]]: [[Make an Object appear on the Mobile Client]].
More precisely, a [[Meta Class]] configured in the ACM can have so-called "possible child classes". If one of those is a document Meta Class, you can create such a document object as a child of an object which has the respective parent Meta Class. A Meta Class is a document, when it has a document classification.
