Solutions to problems related to digital
preservation
• Based on experience and expertise of the “pioneers” of
digital preservation
• All kinds of digital objects
– But
 Audio visual – perhaps better done by PrestoCentre
 Documents and images – perhaps better done by OPF
• Need to:
– Define the solution :

CHALLENGES
• Different types of digital objects e.g.
–
–
–
–
•
•
•
•
Rendered – simple images, sound, video, documents
Data – needs meaning of numbers etc
Software
Time dependent
Many different tools and services – many lists
Many sources – APARSEN members and others
Many terminologies, many glossaries

Integrated vision
• If the payback is not immediate then the resources need to
be justified
• Since the resources have to be found somehow, the
question “who pays and why?” if often heard
• To justify the resources needed for preservation one needs
to identify the potential value.
• To maintain, for even increase, the likely value, the
techniques chosen for preservation plays a key role.

Basic preservation activities
•
Can repeat what has been
done before
BUT
• Cannot use new applications
Libraries say:
•“Emulate or migrate”
•
Convert to format which new
software can use
BUT
• What if there are many
software systems?
–Works well with data only in special cases
 Can repeat what was done before instead of new things
–Does not help with building cross-disciplinary communities

Preservation techniques
For each technique
• look for evidence
– what evidence?
• must at least make sure
we consider different types
of data
–rendered
–composite
–dynamic
–active
vs non-rendered
vs simple
vs static
vs passive
• must look at all types of
threats

Evidence
• APA/APARSEN list of tools:
http://www.alliancepermanentaccess.org/index.php/tools/tool
s-for-preservation/
– details of preservation related software, examples of data
and the evidence of preservation linking software to types of
data. Some of this evidence comes from specific testbeds but
much comes from user scenarios.

Other evidence and tools
• CASPAR project large amount collected evidence about the
effectiveness of tools and services for many different types
of data:
– Scientific
– Cultural heritage
– Contemporary performing arts
• Prototyped the tools and services
• These have been developed in SCIDIP-ES
http://www.scidip-es.eu and http://intplatform.digitalpreserve.info
• Also massive collection of information about views of
thousands of researchers, data managers and publishers
across disciplines and around the world – PARSE.Insight

• We need to:
– Know something has changed

– Identify the implications of that change
Gap
Identification
Service
– Decide on the best course of action for preservation
– What RepInfo we need to fill the gaps

Registry

 Created by someone else or creating a new one
– If transformed: how to maintain data authenticity
– Alternatively: hand it over to another repository

APARSEN test audit findings
• Lack of definition of Designated Community
– SCIDIP-ES Gap Identification Services helps
• Lack of adequate Representation Information
– SCIDIP-ES Registry or RepInfo, Preservation Strategy and
RepInfo Toolkit help to create/share RepInfo
– Orchestration service and Gap Identification Services help
repository manager
• Inadequate Archival Information Packages
– SCIDIP-ES Packaging tools help create AIPs – several flavours
• Lack of hand-over plans

Terminologies – APARSEN DP Glossary
Why another?
• Provides relationships between different terms from the
various glossaries OAIS, APARSEN, DPC, ANZ, SNIA,
INTERPARES, TDR (ISO 16363)
– Uses SKOS to organise the terms – tells us whether a term is
 Broader / narrower / related
to another term
 See
http://www.alliancepermanentaccess.org/index.php/consultancy/d
pglossary/
 Each term has a URI e.g. Representation Information:

Representation_Information
In scheme:
OAIS
Co-funded by the European Union under FP7-ICT-2009-6
Definition:
The information that maps a Data Object into more meaningful concepts. An example of
Representation Information for a bit sequence which is a FITS file might consist of the FITS
standard which defines the format plus a dictionary which defines the meaning in the file of
keywords which are not part of the standard. Another example is JPEG software which is used
to render a JPEG file; rendering the JPEG file as bits is not very meaningful to humans but the
software, which embodies an understanding of the JPEG standard, maps the bits into pixels
which can then be rendered as an image for human viewing.
