  2. Interoperability from the Digital Library Perspective DonatellaCastelli CNR-ISTI donatella.castelli@isti.cnr.it

  3. DL interoperability ICT 2010: "Global Information Structures for Science & Cultural heritage: The Interoperability Challenge" Networking Session • In many domains DLs rely on resource sharing • Aggregation in larger information spaces • Composition to form richer information objects • Implementation of resource sharing requires interoperability • Interoperability is a complex, multidimensional issue

  4. Interoperability dimensions (1) • Organizational: Provider and Consumer business goals and processes • Semantic: meaning of the exchanged resource and its context • Technical: technological solution supporting the Provider and Consumer operation as well as the communication among the two ICT 2010: "Global Information Structures for Science & Cultural heritage: The Interoperability Challenge" Networking Session

  5. Interoperability dimensions (2) DELOS DL Reference Model Content– information available User – actors interacting with system Functionality –operations supported Policy – rules and conditions governing operation Quality – qualitative & quantitative characterisations of system Architecture–physical software (and hardware) constituents concretely realising the DL

  6. Interoperability dimensions (3) • Possible resources under the Content domain • Metadata • Primary Information Object • Identifier • Annotation • Provenance • Vocabularies • .....

  7. Interoperability needs until now ICT 2010: "Global Information Structures for Science & Cultural heritage: The Interoperability Challenge" Networking Session • Interoperability needs • Consumer tasks operate on a small fractions of shared DL resources • Sharing is primarily between trusted organizations • DRIVER &Europeana Search and retrieval of open access metadata from collaborating institutions • Solution: • Guidelines, protocol implementation, standard representations

  8. Emerging interoperability needs ICT 2010: "Global Information Structures for Science & Cultural heritage: The Interoperability Challenge" Networking Session • Example: Creationof a compounddocumentrequiresaccessto: • parts; • operation (toderiveparts); • rights; • provenance; • usersprofile; • qualityinformation; • ……

  9. Solutions maturity Better understood Less understood ICT 2010: "Global Information Structures for Science & Cultural heritage: The Interoperability Challenge" Networking Session Architecture Content Functionality User Quality Policy

  10. Policy interoperability ICT 2010: "Global Information Structures for Science & Cultural heritage: The Interoperability Challenge" Networking Session Very heterogeneous domain Many organizational assumptions No model (s) yet No awareness of the needs of such model yet

  11. DL.org recommendations DL reference Model Interoperability Cookbook Teaching Material ICT 2010: "Global Information Structures for Science & Cultural heritage: The Interoperability Challenge" Networking Session • Interoperability Framework • Clear interoperability problem statements • Well described and clean solutions • DL modelling • Awareness of best practices • Assessment of solutions
