4 Workshop, Beijing, 22nd June 2005 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

5 Workshop, Beijing, 22nd June 2005 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

6 Workshop, Beijing, 22nd June 2005 DILIGENT Goals & Approach Service Oriented Digital Library Infrastructure 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

7 Workshop, Beijing, 22nd June 2005 DILIGENT Architecture

8 Workshop, Beijing, 22nd June 2005 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

9 Workshop, Beijing, 22nd June 2005 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

10 Workshop, Beijing, 22nd June 2005 Types of Involvement for Observers Information about project activities (www.diligentproject.org)www.diligentproject.org Involvement in workshops Possible involvement in validation Feedback for DILIGENT development Candidates for adoption of DILIGENT infrastructure

11 Workshop, Beijing, 22nd June 2005 Contact us Co-operation with other projects/communities is welcome Contact people: Donatella Castelli, Pasquale Pagano, ISTI-CNR Jessica Michael, ERCIM Peter Fankhauser, Fraunhofer IPSI
