Todays talk
  • The DCC
  • Background Context
  • What We Do
  • Digital Preservation Archiving
  • Preservation Curation Issues challenges
  • Specific challenges for repositories receiving
    digital deposits

3
UK Digital Curation Centre
  • JISC Circular 6/03 called for bids in digital
    curation
  • JISC and the e-Science Core Programme funding
  • for development, services and outreach in digital
    curation
  • for a research programme
  • Impetus to action
  • Growth in e-Science activity and data creation
  • Recognition that continuing access to digital
    information is needed

8
Development
  • DCC Approach to Digital Curation (white paper)
    sets out the path for development activities
  • Monitoring international standards
  • Development of a Representation Information
    Registry/Repository (DCC RIR)
  • Development of recommendations for tools and
    methods for generating Representation Information
  • Creating testbeds for digital curation tools
  • Creating auditing and certification processes for
    trusted repositories

9
Services
  • Information Services
  • Community-developed Digital Curation Manual
  • Briefing Papers FAQs
  • Technology Watch
  • Case Studies
  • Best Practice Checklists
  • Advisory Services
  • Events information days, workshops, training,
    conferences
  • Helpdesk
  • Audit and Certification Services

10
Out of scope
  • We dont
  • Accept digital archival materials for curation,
    storage, or preservation
  • Maintain a computer hardware museum
  • Offer file migration or conversion
  • Repair damaged data resources
  • Carry out digital archaeology

11
Summary
  • Support and promote continuing improvement in the
    quality of data curation and preservation
    activity
  • Nurture strong community relationships between
    practitioners, researchers, and curators
  • Address digital curation from all aspects of the
    records life-cycle
  • Develop and promote curation knowledge, tools and
    techniques
  • Identify and research new organisational,
    technical, and supporting curation challenges

12
Digital Curation
  • Digital curation is all about maintaining and
    adding value to a trusted body of digital
    information for current and future use
    specifically, we mean the active management and
    appraisal of data over the life-cycle of
    scholarly and scientific materials.
  • Digital Curation brings a whole host of
    challenges
  • The range of stakeholders that affect the
    survival of digital material cuts across the
    whole life-cycle
  • Everyone plays an important role

13
Preserving Digital Archives I
  • The main problems
  • Technology obsolescence
  • Hardware and software dependencies
  • Leading to authenticity and integrity issues
  • Fragility of digital media
  • Bit deterioration
  • Media breakage
  • Lack of good practice examples for
  • Data creation
  • Data documentation

14
Preserving Digital Archives II
  • Some other problems
  • Cultural
  • Creators dont (want to) understand the technical
    issues
  • Contextual
  • Metadata identifying resources is often
    insufficient
  • Financial
  • Difficult to anticipate costs of different
    activities
  • Organisational
  • Need for collaboration between parties is often
    overlooked
  • Infrastructure and existing procedures often
    inadequate
  • Legal
  • Largely an unknown quantity

15
Receiving Digital Archives I
  • Specific challenges for organisations receiving
    externally originating digital deposits
  • Possible lack of control/influence over
  • resource creation
  • resource collection documentation
  • transfer metadata
  • technical metadata
  • file storage format
  • media storage format

16
Receiving Digital Archives II
  • Further challenges
  • Lack of required hardware to read discs
  • Lack of required software to read file formats
  • Lack of in-house knowledge about digital deposits
  • May be a hybrid collection paper digital
  • This causes further challenges
  • Final archive may only accept limited formats
  • You might have to convert the material for
    archiving
  • Solving all of these issues may cause you money

17
Digital archaeology for digital archiving
  • Digital archaeology
  • A form of data recovery
  • Exploring what is buried below the surface
  • Rescuing neglected and damaged data resources
  • May reveal a lot of unwanted material, but
  • may also reveals some valuable treasures
  • May be necessary if repositories receiving
    digital deposits are to ascertain
  • What material has been deposited
  • Whether the material is valuable
  • How to access and store the material for the
    longer-term

18
Digital Archaeology - Examples
  • NCUACS
  • Received Old BBC Discs obsolete storage format
  • National Archives/CAMiLEON project
  • Domesday Project rescuing data from obsolete
    media and data formats
  • NARA
  • Hurricane Marilyn resulted in weather damaged
    diskettes and 12 inch WORM discs
  • German Unification
  • West German Archivists recovering obsolete East
    German data

19
What can you do?
  • Find a reliable way to explore deposits and
    ascertain the value of the records
  • Some records may be damaged or fragmented
  • Rescue records where possible
  • Store those that are not
  • You never know what we will be capable of in the
    future
  • Most data can be rescued given enough time and
    money

20
How can you do it?
  • Learn from experience
  • What you have done in the past
  • What others have done in the past
  • Collaborate and share knowledge
  • Be prepared
  • To change processes
  • To embark on a learning curve
  • To communicate issues to potential depositors
  • Develop in-house knowledge
  • Cuts costs
  • But be prepared to combine it with specialised
    external knowledge when necessary

21
What can help you?
  • Identify and use tools developed by others
  • DCC tools such as the RIR
  • Erpanet tools on Ingest, Costing, Selecting
    Technologies, Developing a Policy
  • Tools from the NAA
  • Tools from the NLA
  • Tools from the Digital Preservation Testbed
  • Identify and use valuable case studies
  • Ross Gow Digital Archaeology Rescuing
    Neglected and Damaged Data Resources
  • Jeremy John, British Library Digital Manuscripts
    Project
  • Studies presented at this workshop
