in the face of continuing technological
obsolescence

CYBERTERRA INCOGNITA
5
What can we assume about ICT in the future ?
Everything we use will be obsolete
6
What will the future think about our ICT?
It will seem puny
7
What do we know about future ICT?

8
A Roadmap to the DPIF?
  • What Do We Know?
  • What DONT We Know?
  • Some data we want to preserve
  • Current demands
  • Current information technology
  • Technology obsolescence
  • Growing variety and complexity of formats
  • Format Obsolesence
  • How to be sure we pick the right data to preserve
  • How to preserve and sustain access to data in
    most formats being produced
  • Future technology
  • Input capabilities
  • Processing Capabilities
  • Output Capabilities
  • Interface specifications
  • Future Demands

9
The only wisdom we can hope to acquire is the
wisdom of humility Humility is endless.
  • T. S. Eliot

10
Envisioning a Digital Preservation
Interoperability Framework
11
Exterior View Digital Preservation
Interoperability Framework
  • The boundary between what will and will not be
    possible for using preserved digital data
    regardless of
  • Source
  • Location
  • Representation
  • Materialization
  • Inteterval between data production and use

12
Interior View Digital Preservation
Interoperability Framework
  • The principles, concepts, standards and methods
    for buidling and sustaining
  • A multi-channel, multi-media, multi-purpose
    network for asynchronous communication over cyber
    space and time
  • Where we dont know requirements at the receiving
    ends,
  • Other than that they change

13
Mapping the Infrastructure for Digital
Preservation Interoperability
A Cybergraphic Information System Model
14
Mapping the Infrastructure for Digital
Preservation Interoperability
Cyberspace is the locational reference base for
a Cybergraphic Information System Model of the
DPIF
15
Cyberspace
  • The Internet
  • Systems Applications that are connected
    directly or indirectly to the Internet
  • The rules, policies and standards that govern and
    enable production, persistence, communication
    consumption of digital data
  • The 5th dimension
  • Connected to physical spacetime
  • Enabling things to exist and happen that are
    impossible in 4-D
  • Chris Greer , Office of Science and Technology
    Policy
  • Executive Office of the President, USA.

16
Cybergraphic Information System Model for
Digital Preservation
  • Re-use and Re-purposing
  • Information Object Set
  • Information Object
  • Data Object
  • Data
  • Cyberspacetime

17
Preservation Objects in the DPIF
  • An Information Object Set
  • And its subsets and elements
  • Information Object
  • And the Data Objects it comprises
  • Data Object
  • And the Data it comprises

18
Cybertime
  • Enables communications that are
  • Instantaneous
  • Asynchronous
  • Polychronic
  • Elastic

DPIF Capabilities, Characteristics and Services
32
User-Centric DPIF Capabilities
  • Allow users to define collections drawing content
    from various repositories
  • Persist user-defined collections
  • Enable users to invoke services on collections
    from arbitrary providers
  • Support dynamic links between user-defined
    collections and repositories
  • Support appropriate use of data

33
Loci of Preservation Services
  • Within Individual Collection
  • Within Individual Repository
  • Over the DPIF
  • Synergistic
  • Standard across cyberspace
  • Operating between and among collections and
    repositories
  • Internal
  • Implemented within repositories or collections
  • Can be adapted or extended locally
  • Across Cybertime

34
Locus Collection Services
  • Collection Management
  • Collection Services
  • Document Services
  • Repository Services
  • R. Wilensky. Personal Libraries

35
Locus Repository Services
  • Ingest
  • Data management
  • Preservation Planning
  • Dissemination
  • Administration
  • Open Archival Information System Reference Model

36
Locus Over the DPIF

  • Assessment of performance
  • Interface specification for interoperation
  • Negotiation of interoperation contracts
  • Internal Services

    generations of data sets, data types,
    technologies and implementations exist in
    cyberspace at any given time.
  • Persistence
  • Support continued operation of preservation
    services in the face of changes in technology at
    different velocities
  • Graceful Evolution
  • Facilitate transition when changes in services
    are necessitated by changes in technology
  • Facilitate introduction of new services enabled
    by advances in technology.

Building the DPIF
43
Fundamental Characteristics of the DPIF
Users
  • Independent of Implementation
  • i.e., effective across
  • Heterogeneous platforms
  • Independent administration
  • Generations of technology
  • Semiotic domains
  • Evolvable
  • Extensible
  • Agile
  • Interstitial

Data
Ser-vices
44
Development of the DPIF Exterior View
  • The Periphery of the DPIF needs to
  • Facilitate transmission of data into and out of
    the presevation environment
  • Allow local irregularities to enable optimization
    for particular producers, repositories,
    collections, services and for re-use and
    re-purposing
  • Expand gradually

47
Incremental Development of the DPIF
  • Address Users, Data and Services in each
    increment
  • Facilitate the emergence and persistence of
    Networks of Preservation within specialized data
    domains or areas of activity
  • Including various repositories, collections and
    service providers
  • Sharing common standards, data, services,
    contracts
  • Develop Use Cases
  • Enable superposition of Networks of Practice
  • Identify and address barriers to interoperation
