Visualization of Modified Linked Objects 
Local modifications to objects are visualized with symbols. If an object is a delta link and modifications are made to this object, these modifications are visualized as a delta. Only the insertion and modification of objects is visualized, but not the deletion of objects.
The following symbols show whether objects were modified or added:

You can find out what local changes are permitted to a delta link by reading Changing Linked Objects in Roles and Worksets.

Note that
changes are only visualized for delta links. If an object is not a delta link and this object is
changed, these changes are not visualized. An object is not a delta link if it no longer
references any object in the object chain. The object is then the first object in the
object chain, called the master object, on which objects depend, but that is
itself not dependent on any other object. See also
