Development – initial plans
• Registries/Repositories
– offering a repository of tools and technical
information, a focal point for digital curators
– metadata standards
• Testbeds
– for testing and evaluating tools, methods,
standards and policies in realistic settings
• Certification
– standards

Development
What can we rely on in the
Long Term?
• The bits (original or migrated)
– let us for the moment put to one side the issue
of BIT PRESERVATION (but it is an issue)
• Physical documents that people can read
– e.g. ISO standards on paper
• Additional information we collect – either
held by the DCC, its collaborators or
successors

Development
Preservation “vs” Current Use
• There are already very many architectures to
support immediate use of information
– Aim to support these
• Therefore chose to be guided by
– long-term preservation aspects
• try to ensure that components of the preservation architecture
can supplement other “current use” architectures.
– to promote this we should emphasise “interoperability”
and “automated use” as far as possible.
– based initially on OAIS Reference Model – but not
limited to that

Representation Information
vs File Format
• File Format provides only limited information
– Knowing that a file is in Word 6.0 format does not allow one to
understand its contents e.g.
• File contains French text
• File has text with specialised terms
– Science data file (e.g. FITS) also has keywords and values
• What do they mean?
• Representation Information is not limited in this way
– N.B. includes File Format
• See DCC demo
– Registry/Repository of Representation Info
• Low cost of “buy-in”

Standards and Audit &
Certification
• How can people know to whom their
information can be entrusted?
• OAIS follow-on standard(s) underway
– on which a certification program can be based

Industry
• From the standards:
standards bodies
– need to establish accreditation and certification bodies in
preparation for offering audit and certification services
– audit, certification and accreditation are potential sources of
long term funding for the DCC
– Testbeds and testing procedures
• for software certification
• hardware and software systems will need to be purchased,
hired or borrowed.
12
– we expect to work with hardware and software manufacturers to
certify hardware and software components
