Axiomy (2)

"abstraction fn(class)" se rovná attr tehdy a jen tehdy pokud pro všechny inst platí: inst je instancí třídy class tehdy a jen tehdy pokud inst má atribut attr.

(<=>
      (equal
            (AbstractionFn ?CLASS)
            ?ATTR)
      (forall
            (?INST)
            (<=>
                  (instance ?INST ?CLASS)
                  (property ?INST ?ATTR))))

"extension fn(attribute)" se rovná class tehdy a jen tehdy pokud "abstraction fn(class)" se rovná attribute.

(<=>
      (equal
            (ExtensionFn ?ATTRIBUTE)
            ?CLASS)
      (equal
            (AbstractionFn ?CLASS)
            ?ATTRIBUTE))
