1. 1 New Roles in Digital Libraries... José Borbinha National Library of Portugal Direction of Services for Innovation and Development

2. 2 “Digital Libraries”??? Issues and cases in digital libraries: –the main cases New content genres, metadata,... –about interoperability Projects LEAF and TEL... –about actors The DELOS/NSF Working Group... –...one global vision, BND... The National Digital Library (Portugal)

3. 3 An historical perspective Libraries and technology among the times...

4. 4 A Computer Science’s perspective ACM Computing Classification System (January 1998)... H. Information Systems –... –H.3 Information Storage and Retrieval... H.3.7 Digital Libraries –Collection –Dissemination –Standards –System issues –User issues

5. 5 A perspective of a traditional library User Registered Anonymous Librarian Actor CreatorEditor Distributor Preservation Publication LicensingAcquisition RegistrationDissemination Search Digital Library Access

6. 6 Use Cases (from the model)... Publication –Availability of a manifestation of a work (resource)... Licensing –Rules for the usage of an item of a resource... Acquisition –Ownership of a resource... Registration –Create metadata to describe the resource... Dissemination –Making aware the existence of a resource... Search –Searching of information about a work (resource discovery). Access –Visualization of a resource, duplication,... Preservation –To keep the resource in good shape for access...

7. 7 Another view of the cases... AcquisitionDelivery by the publisher Capture by the library Harvesting by the library VerificationMedium integrity Content integrity Logical integrity Authentication Registration Metadata Bibliographic and content description Installation and de-installation Preservation Access Preservation Physical preservationMedium refreshing Medium migration Logical preservationFormat conversion Emulation Intellectual preservation Access Conditions of use Local access Remote access

8. 8 Genres (what?) –Information resource’s media, formats, type, characteristics (on-line/off-line, dynamic resources, interactive resources,...) Actors (who?) –Need to review concepts and roles (editor, creator, contributor, translator, illustrator, distributor, owner, user, librarian, host, mediator,...) Identifiers (where?) –Names, uniform names and identifiers, contextual names and identifiers, persistency,... Metadata (how?) –Bibliographic description, administration, structural description,..., creation versus reutilization,... Emerging issues...

9. 9 Bibliographic description of the resources Bibliographic description and identification of the resources, such as titles, authors, indexing terms, classification, abstracts, surrogates, etc. Administration of the resources Administrative information about the resource, such as information about acquisition process and costs, rights, etc. Preservation of the resources Technical or management requirements for long term preservation. Technical and structural description of the resources Technical requirements to manipulate the resource (systems and tools), etc. Access, usage and reproduction of the resources Information about terms and conditions for access and reproduction, etc. Administration of the metadata Information about the other metadata classes, such as data of creation, origin, authenticity, terms and conditions for its usage, etc. Classes of metadata

19. 19 WG Members DELOS (Europe) José Borbinha, National Library of Portugal (DELOS coordinator) Michel Mabe, Elsevier Science, UK (Publishing industry) Peter Mutschke, Social Science Information Centre, Germany (Software agents, Information Retrieval) Hans-Jörg Lieder, Berlin State Library, Germany (LEAF project) NSF (USA) John Kunze, University of California, USA (NSF coordinator) Barbara Tillett, Library of Congress, USA (Libraries) Becky Dean, OCLC, USA (Libraries services) Angela Spinazze, USA (Museums) Howard Besser, University of California, USA (Multimedia and digital art production) DCMI - Dublin Core Metadata Initiative Warwick Cathro, National Library of Australia

20. 20 Purpose of Actors Working Group “… to develop a reference model describing the different classes of actors related to the problem of the Digital Library, including their roles and implications.” - traditional entities (authors, editors, publishers) - non-traditional (users, catalogers, ref. librarians) - emerging (software agents, mediators, special rights holders)

21. 21 Actors in Digital Libraries???... are persons, organizations, and automata that play roles in the production, dissemination, management and use of digital information.

22. 22 Results White paper: –Definition and introduction to the problem. –Description and analysis of the requirements. –Proposal to the community for a reference model. –Proposals for an international agenda for further technical and collaborative developments.
