4. 4 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

5. 5 Information Space for DLs Structure of Data Structure of Behavior Digital Libraries Databases/IR Web Low High

6. 6 Conceptual Framework Contents Management Usage Digital Library System

7. 7 Current Methodology

8. 8 Content-centric Targeted for static storage Environment-specific Isolated and repeated efforts Isolated systems

9. 9 Current Myths Digital Libraries are for things in Libraries only Digital Libraries are for Cultural Heritage only

10. 10 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

11. 11 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 Grand 10-Year Vision #2

12. 12 Future Digital Libraries Person-centric Targeted for active communication/collaboration Global distributed interacting systems “All” applications Content-centric Targeted for static storage Environment-specific Isolated and repeated efforts Isolated systems

13. 13 Digital Library Management Systems Management Visualisation (generic) User Interface (generic) Access (generic) Preservation (generic) Visualisation (specialised) User Interface (specialised) Access (specialised) Preservation (specialised) Spoken-Word Audio Mgmt Personalisation Customisation

14. 14 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

15. 15 Future Digital Library Development

16. 16 Conceptual Frameworks Operational Context Stakeholders Architectural Environment Information Object Abstractions Functional Power and Workflow Environment

17. 17 Operational Context 'Society' UsersProviders ` Science ’

18. 18 Operational Context 'Society' DL Information Space (One instantiation per 'society‘) UsersProviders Interfaces

19. 19 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

20. 20 Stakeholders - Applications DLs as parts of larger organizations and application contexts:  Health  Inclusion  Science  Government  Culture  Learning...  Libraries, Museums, Archives, Hospitals, …

21. 21 Architectural Environment END- USERS RAW DATA sensors terminal devices distributed processing network processing tools knowledge fragments information fragments PROVIDERS DL SOCIETY 1 2 3 1 4 heterogeneous elements REAL WORLD

22. 22 Architectural Environment Raw data Information fragments Knowledge fragments User terminal devices Sensors Network of processing units

23. 23 Information Object Abstractions 'Society' Vocabulary (Domain specific) Pragmatic Semantics Formal Semantics Generic Semantics Syntax Middleware Binary Objects Bits & bytes DL

24. 24 Functional Power & Wflow Environment Acquisition Modeling Management Mediation Access Distribution Interpretation and translation User-defined task-specific activities

25. 25 Future Research Directions Circles of User Experience Layers of System Architectures Person-centric research System-centric research Foundation research

26. 26 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....)

27. 27 Foundations Architectures  Grid?  Peer-to-Peer?  Service-oriented?  All of the above? Theories Unifying paradigms DL models Digital Library Reference Model

28. 28 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

29. 29 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

30. 30 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)

31. 31 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

32. 32 Vision Danger Antidotes Dealing with the avalanche of information available Protection of individuals’ privacy from sensors Balance between privacy and personalization

33. 33 Research Methodology DL Information Space Content UsersContent Producers 'Society' Work involving Information Space and Content Communities Work done autonomously within DL-IS Generic Work

34. 34 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

35. 35 Name (Adjective) (bit abstraction) (created entity) Digital Libraries  Adjective = digital  Bit abstraction = <>  Created entity = library

36. 36 Name Collaborative Ambient Universal Dynamic Pervasive Digital Knowledge Information Data Libraries Environments Spaces Gardens Architectures Forums Factories Worlds Realms Agoras
