  endangered because of technological
  deterioration
• Registration of technical metadata --gt Which
  software and hardware is necessary to view the
  digital item in the future?

A Preservation Layer Model contains 4 abstraction
levels
Autonomous Digital Item

• The Data format identifies the structure and
  meaning of a bit-stream, like a .PDF file

• The structure and meaning of the bit-stream are
  defined within the application logic of a
  specific Viewer Application. Used for creating,
  modifying, and presenting the information in the
  specified format

• The Operating System contains the functionalities
  that all viewer applications need like access to
  a printer or scanner, and fundamental
  requirements like file structure

• Reference platform

• The Reference Platform specifies how the bits and
  bytes are transformed to a physical
  representation like for example on a screen
