Resource discovery and information sharing: reaching the 2.0 turn Resource discovery and information sharing: reaching the 2.0 turn Presentation Transcript

  • Resource discovery & information sharing: reaching the 2.0 turn Bonaria Biancu aka The Geek Librarian Biblioteca di Ateneo Università di Milano-Bicocca Trento, ITC-IRST-SRA 21-22 Agosto 2006
  • Web 2.0
    • October 2004 – Tim O’Reilly coined the term Web 2.0
      • The web as a platform
      • Harnessing collective intelligence
      • Rich user experience
      • The long tail
      • Hackability
      • Perpetual beta
      • Architecture of participation
      • Granular accessibility of content
  • Library 2.0
    • September 2005 – Michael Casey ( Library Crunch ) coined the term Library 2.0 = web 2.0 concepts and applications in the LIS realm (but there isn’t agreement on the definition)
    • and also…
    • Librarian 2.0 = Librarian + Web 2.0
    • L2 is not just technology, it is an attitude (nevertheless web 2.0 is a significant part of the equation)
  • What – How – Why (from a geek lib perspective)
    • What: ILS disaggregation, recombination and integration [see Talis ]
    • How: (open code/standards +) API, Mashups [see Programmable Web ], AJAX [see OJAX ], Greasemonkey [see LibraryThing Thing ], Firefox Plugins [see Del.icio.us search plugins ]…
    • Why: Putting libraries out of the walled gardens (breaking information silos)
    • => remix content – foster user participation
    • Early adopters: WPOPAC , Penn Tags
  • How L2 works in libraries
    • OPAC 2.0 : records tagging, RSS for search results, acquisitions and alerts, user agents, openurl, federated search, user reviews, open search, recommendations, communities (Googlezon model)
    • Subject based wikis
    • Bloglines trusted feeds
    • Library blogs
    • IM reference
    • RSS alerts for library news
    • Pod-video-casting guides to library services
    • Personal search engines for reference (Swiki, Gigablast)
    • Collaborative web (MySpace, Protopage, NetVibes…) for communicating with users
    • OPML [see L2 ALA blog ], social bookmarking [see Del.icio.us ], and social tagging [ CiteULike , Flickr …] for integration with VLEs
  • Scout Portal Toolkit : a Resource Description, Organization and Discovery Tool
    • A project funded by Mellon Foundation, builded by University of Wisconsin-Madison’s Internet Scout Project in 2000
    • Now (2006) fully tested – vers. 1.4.x (1.3.1 adopted by UNIMIB)
    • In Italy 4 instances: VL Cilea , AIB-DFP , FORMEZ , UNIMIB ; others coming
    • Abroad: lots… (National Finnish Library Science Link House is a very good model)
  • Scout @ UNIMIB = LINX – Link e strumenti X la ricerca
    • System Configuration: layout, search options, users rights…
    • Metadata Field Editor: DCMES - ANSI/NISO Z39.85-2001, some DC qualifiers , some fields (overlapping) IEEE LOM
