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
• From the standards: – 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. – we expect to work with hardware and software manufacturers to
certify hardware and software components
