Introduction to DLTP

Digital Long Term Preservation (DLTP)

Where to begin?

Imagine you find a digital copy of a media file that you want to use…

Step by step

You want to use/open it:

  • What is it stored on?
  • What do you do?
  • What do you expect?
  • What do you think is necessary for that to be possible?

Components to deal with?

  • Which carrier?
  • Which format?
  • Which properties?
  • Which player/tools?
  • Which storage?
  • Which catalog/database?
  • For whom?

Layers / Components

Onions.

Layers / Components

  • Physical carrier (+drive?)
  • Hardware interface (controller, cables, schematics, …)
  • Software interface (driver, protocols, …)
  • Filesystem
  • The File
  • Container format
  • Content format(s) (codecs, MD formats, etc)
  • The actual content.

The other direction

You were looking for something specific in a collection…

Okay, Digital:

Layers / Components

  • A Collection
  • A tool to search & find
  • Retrieve data from storage
  • Access a copy
  • The File

The Challenge Begins
