File formats
-
Device obsolescence
-
File format obsolescence
Software supporting the
format fails in the marketplace or is
bought by a competitor and
withdrawn.
-
File format obsolescence
Software upgrades fail to support legacy files
The format itself is superseded by
another or evolves in complexity
The format "take up" is low or
industry fails to create compatible
software
The format fails, stagnates, or is no longer compatible with the current
environment

If you don't have the software,even a perfectly preserved document is of no use.

As a componentof how we manageour digital assets
-
Why digital asset management?
● We are a knowledge organization● Knowledge workers spend 30-40%
of their time on document related tasks● This increases significantly when
other digital assets are taken into consideration● Digital assets are increasing and increasingly
easy to lose● Digital assets form the basis of much of our
research
-
Digital archiving and preservation● Institutional papers and documents
Other digital assets
● Historical papers● Library collections● Various history projects● Rockart collections ● Video and audio collections
● e.g. Wits TV● Donations of significant collections
from industry● History of human evolution research● Research output and theses● Research data

Workflow
-
WeWe Basics● Rules-driven workflow engine● Rules represented in XML● Sequential event support● Conditional Return support● Written in Perl● Uses PostgreSQL Database● Open Source ● Originally developed for The University of the
Witwatersrand, Johannesburg● Multiple Management interfaces
-
WeWe Designer● Web-based design tool for designing
workflows● Supports multiple events with multiple return
types/states● Drag and drop interface● Written in JQuery● Open Source Interface● Adapt from Design “Template” support
-
WeWe Developer● Developers create Rules Modules● Modules can be written in Perl or any other
language that can be executed from the Linux commandline
● API● Commandline Interface

The real challengeis getting the documentscanned and into aPDF and sent off to somewhere meaningful.
Thats why we needexpensive documentimaging software.
Right?
-
Let's have one digital asset management project for Wits and let us create the synergy
that leads to innovation.
