Scope note: This property identifies the E24 Physical Man-Made Thing modified in an E11 Modification. If a modification is applied to a non-man-made object, it is regarded as an E22 Man-Made Object from that time onwards. Examples: - rebuilding of the Reichstag (E11) has modified the Reichstag in Berlin (E24) In First Order Logic: P31(x,y) ⊃ E11(x) P31(x,y) ⊃ E24(y) P31(x,y) ⊃ P12(x,y)
