Transcript

  • 1. Persona-based development of a new discovery system using open-source components Karin Clavel, TU Delft Library, the Netherlands
  • 2. 1. “ Replace the OPAC with a more user-friendly system”
  • 3. Key features
    • Google-like search box
    • searches multiple sources at the same time
    • accommodates students, scholars and corporate customers
    • facetted search
    • Web2.0 elements: RSS, tags, comments
    • nice looking, intuitive user interface
  • 4. 2. Are we in touch with our users’ needs? Tamara Adlin on http://www.adlininc.com/
  • 5. Design for just one person
    • Alan Cooper, 2004:
    • If you want to create a product that satisfies a broad audience of users, logic will tell you to make it as broad in functionality as possible to accommodate the most people.
    • Logic is wrong.
    • You will have far greater success by designing for a single person.
  • 6. We design for Sophie!
    • Who is Sophie?
      • Architecture student
      • Main goal: inspiration
      • Books with photos and stories
      • Articles about building technology
      • Images, maps, photos
      • Searches by cover
      • Wants to consult peers or teacher when searching
      • A persona…
    • Our new integrated search system is built for Sophie…

  • 8. Eye-opener
    • Both students and business customers would like a system that is more focused on the search process. They want to be able to resume the process at a different time, maybe with different people helping them.
    • Libraries tend to focus on more hits, better hits, not on the process.
    Using your system, I want to become a better searcher …
  • 9. 3. Discover!
  • 10.  
  • 11. 4. MERESCO open-source components
  • 12. MERESCO component library
    • MERESCO is an open-source library of components for (meta)data management.
    • It supports creating flexible, scalable and open (meta)data management systems such as repositories, search engines and archives.
    • Source: meresco.com
  • 13. Meresco components standardise & normalise store index SRU UI & services harvest metadata sources Harvest: - Meresco OAI-PMH harvester - Aleph harvester
  • 14. Meresco components standardise & normalise store index SRU UI & services harvest metadata sources XSLT, XML Crosswalk - standardise to MODS - normalise author names, dates, languages, document types
  • 15. Meresco components standardise & normalise store index SRU UI & services harvest metadata sources
    • Store one “document” as many parts:
    • original metadata and MODS
    • ratings, reviews, full text …
  • 16. Meresco components standardise & normalise store index SRU UI & services harvest metadata sources
    • Index
    • Lucene full text index
    • Facet index
    • N-gram index
  • 17. Meresco components standardise & normalise store index SRU UI & services harvest metadata sources Query parser: - Google-like to SRU - Boolean to SRU SRU interface
  • 18. Meresco components standardise & normalise store index SRU UI & services harvest metadata sources Availability, link to full-text RSS LibraryThing Loan, renew, order Rate, review
  • 19. Going open source:
    • reuse
    • experiment and learn
    • sharing knowledge
    • complete control
    • independence
    • a little cheaper…
    • no strong community (yet)
    • dependence
    • more work and money than you think…
    YES NO
  • 20. Going open source…
    • … was worth it!
