Expiration Rules are used to determine the objects life time.

After the desired time all the objects referencing an expiration rule will get the specified spikeCode or an expiration workflow will be applied to them.

An expiration rule can be referenced only by a partition. All the objects referencing that partition will reference also the expiration rule.

You may want to create expiration rules for the folders with the content that has to be deleted automatically, e.g. wires etc.
