+==========================
+Automated Tagging Of Files
+==========================
+
+Nextcloud's Files Automated Tagging app allows to assign collaborative tags
+to files and folders based on rules, similar to :doc:`access_control`.
+
+Assigning restricted and invisible tags
+---------------------------------------
+
+The main functionality of this app is to allow users to indirectly assign
+restricted and invisible tags to files they upload.
+
+This is especially useful for retention and :doc:`access_control`, so people
+that got the files shared can not remove the tag to stop the retention or
+allow access against the owners will.
+
+
+    .. figure:: images/automated_tagging_sample_rule.png
+       :alt: Sample rule to assign a restricted tag.
+
+In the sample you can see a simple rule with only one condition.
+It will tag all files with the restricted tag ``Protected file`` that are
+uploaded into a folder that is tagged with ``Protect content``. No user can
+remove the tag ``Protected file`` and therefor access control and retention
+both work fine without users being able to work around them.
+
+Available rules
+---------------
+
+The available rules can be seen in the access control section: :ref:`available-rules-label`.

+==================
+Retention Of Files
+==================
+
+Nextcloud's Files Retention app allows to automatically delete files that
+are tagged with a collaborative tag and have a certain age.
+
+Sample
+------
+
+    .. figure:: images/retention_sample.png
+       :alt: Sample rule to delete files after 14 days.
+
+The rule from the sample will delete all files tagged with ``Temporary file`` after 14 days.
+
+Common misconfigurations
+------------------------
+
+Public collaborative tag
+========================
+
+Similar to :doc:`access_control` retention should use ``restricted`` or ``invisible``
+tags. Otherwise any user can remove the tag and the file is not removed after the given
+period. Use :doc:`automated_tagging` to assign such tags to newly uploaded files.
+
+File age
+========
+
+Currently retention is based on the creation date of the file. The sync client sends
+the original creation date to the server, while uploading through the web interface
+will create a new file with a new creation date.
+We hope to be able to add a ``upload date`` to the filesystem soon, which would make more
+sense. Until then this potentially unexpected behaviour has to be taken into account.
