Digital dark age - Are we doing enough to preserve our website heritage?


Published on

While creating web sites we often see their lifespan only for up to 3 to 5 years. With every relaunch
and overhaul we are confronted with content migration and short term motives to delete maybe
valuable content. On the other hand what is the value of our content? Can we assess it
meaningfully? Do we really know in which context it is used?
Scientist stated that where as we are producing more and more digital artifacts we fail to see that
we are not keeping an eye on preserving it in a manner that will enable us to find and use it in more
that a few years in the future.
This talk will introduce you the aspects of digital preservation with a special look on how TYPO3 is
preparing to help it users to create a digital heritage.
This Talk is part of the "Concise Preservation by combining Managed Forgetting and
Contextualized Remembering" Project ForgetIT. The ForgetIT project is funded by the EC within the
7th Framework Programme under the objective "Digital Preservation" (GA 600826).

  28. 28. 3 Concepts of ForgetITManaged ForgettingContextualized RememberingSynergetic PreservationFreitag, 31. Mai 13
  29. 29. Managed ForgettingManaged Forgetting models resource selection asa function of attention and significancedynamics.It is inspired by the important role of forgetting inhuman memory and focuses on characteristicsignals of reduction in salience. For this purpose itrelies on multi-faceted information assessmentand offers customizable preservation optionssuch as full preservation, removing ofredundancy, resource condensation, and alsocomplete digital forgetting.Freitag, 31. Mai 13
  30. 30. Contextualized RememberingContextualized Remembering targets keepingpreserved content meaningful and useful.It will be based on a process of dynamicevolution-aware contextualization, whichcombines context extraction and packaging withevolution detection and intelligentrecontextualization.Freitag, 31. Mai 13
  31. 31. Synergetic PreservationSynergetic Preservation crosses the chasm thatexists between active information use andpreservation management by making intelligentpreservation processes an integral part of thecontent lifecycle in information management andby developing solutions for smooth bi-directionaltransitions.Freitag, 31.
