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

  6. Conceptual Framework Usage Management Contents Digital Library System

  7. Current Methodology

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

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

  10. Grand 10-Year Vision #1 Digital librariesshould 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. Grand 10-Year Vision #2 The potential exists for digital libraries to become theuniversalknowledgerepositoriesandcommunication conduitsforthefuture,acommonvehiclebywhicheveryonewillaccess,discuss, evaluate, and enhanceinformationofallforms

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

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

  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. Future Digital Library Development

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

  17. 'Society' Operational Context Users Providers `Science’

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

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

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

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

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

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

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

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

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

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

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

  36. Digital Data Pervasive Information Dynamic Knowledge Universal Ambient Collaborative Name

  37. Rebirth of the Field DIGITAL LIBRARIES DYNAMIC UNIVERSAL KNOWLEDGE ENVIRONMENTS

  38. Rebirth of the Field DIGITAL LIBRARIES DYNAMIC UNIVERSAL COMMONS of KNOWLEDGE
