3 DL Definition What: information and services comprehensive rich forms and kinds read-and-expand-only Why: learning and research When: value at depth of time 3

4 Information Space for DLs High Databases/IR Structure of Behavior Digital Libraries Web Low Structure of Data High 4

5 Conceptual Framework Usage Management Contents Digital Library System 5

6 Current Methodology 6

7 Current Methodology Content-centric Targeted for static storage Environment-specific Isolated and repeated efforts Isolated systems 7

8 Current Myths Digital Libraries are for things in Libraries only Digital Libraries are for Cultural Heritage only 8

9 Grand 10-Year Vision #1 Digital libraries should enable any citizen to access all human knowledge anytime and anywhere, in a friendly, multi-modal, efficient, and effective way, by overcoming barriers of distance, language, and culture and by using multiple Internet-connected devices 9

10 Grand 10-Year Vision #2 The potential exists for digital libraries to become the universal knowledge repositories and communication conduits for the future, a common vehicle by which everyone will access, discuss, evaluate, and enhance information of all forms 10

11 Future Digital Libraries Content-centric Person-centric Targeted for static storage Targeted for active communication/collaboration Environment-specific Isolated and repeated efforts Isolated systems Global distributed interacting systems All applications 11

12 Digital Library Management Systems Visualisation (specialised) Personalisation Customisation User Interface (specialised) Visualisation (generic) User Interface (generic) Management Access (generic) Preservation (generic) Access (specialised) Spoken-Word Audio Mgmt Preservation (specialised) 12

13 Future Digital Libraries Person-centric Targeted for active communication/collaboration Generic technology for DLMS Environment-specific needs on top of them Maximum reuse Global distributed interacting systems All applications 13

14 Future Digital Library Development 14

15 Conceptual Frameworks Operational Context Stakeholders Architectural Environment Information Object Abstractions Functional Power and Workflow Environment 15

16 Operational Context 'Society' Users Providers `Science 16

17 Operational Context 'Society' Users Providers Interfaces Interfaces DL Information Space (One instantiation per 'society ) 17

18 Stakeholders Past-Present: users and providers are mutually exclusive sets Future: `user and `provider are roles Same actor may play both roles at different times DLs at the center of scientific activity (collaboration & communication tool) Increases set of actors and set of applications 18

19 Stakeholders - Applications DLs as parts of larger organizations and application contexts: Health Inclusion Science Government Culture Learning... Libraries, Museums, Archives, Hospitals, 19

20 Architectural Environment END- USERS 1 terminal devices 2 distributed processing network knowledge fragments information fragments REAL WORLD 1 PROVIDERS 3 RAW DATA 4 processing tools heterogeneous elements DL sensors SOCIETY 20

21 Architectural Environment Raw data Information fragments Knowledge fragments User terminal devices Sensors Network of processing units 21

22 Information Object Abstractions Pragmatic Semantics Formal Semantics Vocabulary (Domain specific) Generic Semantics Syntax Middleware Binary Objects Bits & bytes 'Society' DL 22

23 Functional Power & Wflow Environment Acquisition Modeling Management Mediation Access Distribution Interpretation and translation User-defined task-specific activities 23

24 Future Research Directions Circles of User Experience Person-centric research Layers of System Architectures System-centric research Foundation research 24

25 Foundations Functionality specification for new objects Multi-perspective object access and tagging Integrated/unified access to digital repositories Lifecycle management Multi-modal functionality combination On-line availability and transcoding DLMS specification, design, development Application interfaces Evaluation (metrics, benchmarks...) 25

26 Foundations Architectures Grid? Peer-to-Peer? Service-oriented? All of the above? Theories Unifying paradigms DL models Digital Library Reference Model 26

27 Person-Centric Research Balancing cognitive load between user and information environment Collaboration, social context Personalized, customized, context-dependent, task-specific, knowledge-based, goal-oriented user/information interaction Harvest info across linguistic boundaries 27

28 Person-Centric Research Adding personal memory to global memory, originator notification Distributed (peer-to-peer) data creation/publication Communication via annotations Tools for building communities Accessibility, usability 28

29 System-Centric Research Interoperability, system integration Security, privacy, authorization Mobile environments Lossless workflow management Information transformations across media types Multi-perspective functionality (multi-level features) 29

30 System-Centric Research Optimization of search processes (distributed, multi-feature, multi-object optimization) Transactional processes, service composition, process verification/check Perceptual object manipulation and transformation, doc recombination Information trading in DL federations 30

31 Vision Danger Antidotes Dealing with the avalanche of information available Protection of individuals privacy from sensors Balance between privacy and personalization 31

32 Research Methodology 'Society' Content Users Content Producers Generic Work Work involving Information Space and Content Communities Work done autonomously within DL-IS DL Information Space 32

33 DELOS Brainstorming Workshop Corvara, 7/2004 About 25 participants Most from Europe, two from the US Initial plenary session Results of DELOS FP5 activities (brainstorming workshops, working groups, etc.) Participants visions of future Parallel sessions of three competing groups Plenary session of groups results Plenary session of integrated outcome 33

34 Name (Adjective) (bit abstraction) (created entity) Digital Libraries Adjective = digital Bit abstraction = <> Created entity = library 34

35 Name Digital Pervasive Dynamic Universal Ambient Collaborative Data Information Knowledge Libraries Environments Spaces Gardens Architectures Forums Factories Worlds Realms Agoras 35
