2. Outline
1. Background on digital preservation
1. Threats and strategies
2. OAIS-reference model
3. APARSEN Network of Excellence on Digital Preservation
2. Reporting on “HisTel” project
3. Digital Preservation
• Threats to future access to digital information
– Format obsolescence
– Not possible to render object
– Operating system obsolescence
– Hardware failure
– What is it?
• Strategies
– Technology preservation strategy
– Technology emulation strategy
– Digital information migration strategy
4. Reference Model for an Open archival
Information System (OAIS)
• ISO 14721: 2012
• OAIS = Archive that accepted responsibility to
preserve information and make it available for a
Designated Community
• Open = Developed in open forums
• Framework for Long Term Preservation Strategies
• Framework for describing and comparig architectures
• Expands consensus on elements and processes for LT
preservation and access
5.
6. Designated Community
• An identified group of potential Consumers who
should be able to understand a particular set of
information. The Designated Community may be
composed of multiple user communities. A
Designated Community is defined by the Archive
and this definition may change over time.

14. State of art HisTel
• Goal: to create a durable infrastructure to provide
access to historical statistics
• DANS-EASY = Back-office
• High priority for:
– Persistent identifiers for tables
– Automatic log-in / Single sign-on
– License update
• Front-office?
– Not decided yet
– www.volkstellingen.nl is outdated
15. Issues:
• How to cope with new versions / adjustments of
datasets?
• Which services should developed on top of the
digital archive? (e.g. Image viewer? GIS-tool?)
• Which digital objects should be archived?
(TabLinker, TabExtractor, Bedford’s Law Script?,
Open Annotation Ontology, etc.)
• Which Representation Information is required?
• Designated Community?
