Combining Asset Collections
---------------------------

**Includes** is available under the *Settings* tab.
It controls what other collections are visible in (i.e. referenced, not copied into) the current collection.
The choice of collections to include is restricted to collection types that are either required or permitted for the current collection type.

.. Note:: *Includes* are technically managed by setting the standard *owl:imports* property from one collection to another.

**Included-By** is available under the *Settings* tab.
It lists the other collections that include the current collection.
The *Included By* list is derived from the inverse of the *Includes* that are set by users.
It cannot be set directly.


.. Note:: Assets that are included in the current collection cannot be modified but can be extended (i.e. a property value cannot be removed but a new property value can be added).
