Basic usage. The OPPL engine takes the target ontology and OPPL script as inputs, and generates a new ontology changed according to the OPPL script. The OPPL script queries the reasoner for a class with a certain restriction (SELECT... WHERE clause, blue) and adds another restriction to the retrieved class (ADD clause, red).
