The selection conditions to be applied are: InstanceOfName extracts instances and values by name, InstancesOfClass and InstancesOfDirectClass extract the instances/values by their defining classes/datatypes, InstanceWithPropertyValue extracts the instances by the values they assume possibly on some properties, and InstanceOfPropertyValue extracts the object of the indicated property values. 32
