Scope note: This property identifies the E77 Persistent Item or items that cease to exist due to a E81 Transformation. It is replaced by the result of the Transformation, which becomes a new unit of documentation. The continuity between both items, the new and the old, is expressed by the link to the common Transformation. Examples: - the transformation of the Venetian Loggia in Heraklion into a city hall (E81) transformed the Venetian Loggia in Heraklion (E22) - the death and mummification of Tut-Ankh-Amun (E81) transformed the ruling Pharao Tut-Ankh-Amun (E21) In First Order Logic: P124(x,y) ⊃ E81(x) P124(x,y) ⊃ E77(y) P124(x,y) ⊃ P93(x,y)
