Research today

• Research is carried out by groups of individuals,
  belonging to different institutions, that
  dynamically aggregate to carry out projects
  together
• By sharing their resources these individuals
  create better conditions for their research
• Digital libraries that maintain the produced
  knowledge and make it accessible worldwide are
  becoming key instruments for scientific
  collaboration in many research areas

Digital library challenges

• Cost Time
• The construction and management of a DL requires
  high investments and specialized personnel
• Years are spent in designing and setting up a DL
• New functionality is computationally expensive
• Multimedia indexing, clustering e.g. LSI
• Multimedia querying e.g. Image retrieval by
  feature vectors
• Multimedia processing e.g. Satellite images
• Heterogeneity Distribution
• DLs (and underlying components) use different
  models, apis
• DLs are distributed/replicated

• Based on EGEE
• High computing and storage capabilities for
  handling a wide variety of information objects
• Controlled Sharing of Resources
• Basic Services for
• DL Creation Management
• Indexing, Search, Data Fusion
• Content Metadata Management
• Process Management
• Testbed for User Scenarios
• Earth Sciences
• Cultural Heritage

Some Methodological Challenges

• Service Oriented, Distributed Architecture
• Requires open systems for
• indexing, searching, feature extraction, metadata
  management
• Distributed Search
• Query Optimization
• Semantic Data Integration
• On Demand Service Activation
• Satellite Images
• Extraction
• Virtual Organizations
• Content Security
• Resource Security

Complementary User Scenarios

• Earth Science Domain
• Well-established tradition in exploiting new
  technologies
• Wide variety of content types (maps, satellite
  images, measurements, text)
• Very large, dynamic data sets
• Support for community events, report generation,
  disaster management.
• Cultural Heritage Domain
• IT technology exploitation still in infancy
• Multidisciplinary collaborative research
• Image based retrieval/semantic analysis of images
• Support for research and teaching
