Persona-based development of a new discovery system using open-source components

  1. 1. Persona-based development of a new discovery system using open-source components Karin Clavel, TU Delft Library, the Netherlands
  2. 2. 1. “ Replace the OPAC with a more user-friendly system”
  3. 3. Key features <ul><li>Google-like search box </li></ul><ul><li>searches multiple sources at the same time </li></ul><ul><li>accommodates students, scholars and corporate customers </li></ul><ul><li>facetted search </li></ul><ul><li>Web2.0 elements: RSS, tags, comments </li></ul><ul><li>nice looking, intuitive user interface </li></ul>
  4. 4. 2. Are we in touch with our users’ needs? Tamara Adlin on http://www.adlininc.com/
  5. 5. Design for just one person <ul><li>Alan Cooper, 2004: </li></ul><ul><li>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. </li></ul><ul><li>Logic is wrong. </li></ul><ul><li>You will have far greater success by designing for a single person. </li></ul>
  6. 6. We design for Sophie! <ul><li>Who is Sophie? </li></ul><ul><ul><li>Architecture student </li></ul></ul><ul><ul><li>Main goal: inspiration </li></ul></ul><ul><ul><li>Books with photos and stories </li></ul></ul><ul><ul><li>Articles about building technology </li></ul></ul><ul><ul><li>Images, maps, photos </li></ul></ul><ul><ul><li>Searches by cover </li></ul></ul><ul><ul><li>Wants to consult peers or teacher when searching </li></ul></ul><ul><ul><li>A persona… </li></ul></ul><ul><li>Our new integrated search system is built for Sophie… </li></ul>Picture by Dr. Hemmert on Flickr.com
  7. 7. … and for Roger, Bert, Hans, Koen and Lily Pictures by ddamredhead, badjonni, Baked Beans, deansouglass, kryptos86 on Flickr.com
  8. 8. Eye-opener <ul><li>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. </li></ul><ul><li>Libraries tend to focus on more hits, better hits, not on the process. </li></ul>Using your system, I want to become a better searcher …
  9. 9. 3. Discover!
  10. 11. 4. MERESCO open-source components
  11. 12. MERESCO component library <ul><li>MERESCO is an open-source library of components for (meta)data management. </li></ul><ul><li>It supports creating flexible, scalable and open (meta)data management systems such as repositories, search engines and archives. </li></ul><ul><li>Source: meresco.com </li></ul>
  12. 13. Meresco components standardise & normalise store index SRU UI & services harvest metadata sources Harvest: - Meresco OAI-PMH harvester - Aleph harvester
  13. 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
  14. 15. Meresco components standardise & normalise store index SRU UI & services harvest metadata sources <ul><li>Store one “document” as many parts: </li></ul><ul><li>original metadata and MODS </li></ul><ul><li>ratings, reviews, full text … </li></ul>
  15. 16. Meresco components standardise & normalise store index SRU UI & services harvest metadata sources <ul><li>Index </li></ul><ul><li>Lucene full text index </li></ul><ul><li>Facet index </li></ul><ul><li>N-gram index </li></ul>
  16. 17. Meresco components standardise & normalise store index SRU UI & services harvest metadata sources Query parser: - Google-like to SRU - Boolean to SRU SRU interface
  17. 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
  18. 19. Going open source: <ul><li>reuse </li></ul><ul><li>experiment and learn </li></ul><ul><li>sharing knowledge </li></ul><ul><li>complete control </li></ul><ul><li>independence </li></ul><ul><li>a little cheaper… </li></ul><ul><li>no strong community (yet) </li></ul><ul><li>dependence </li></ul><ul><li>more work and money than you think… </li></ul>YES NO
  19. 20. Going open source… <ul><li>… was worth it! </li></ul><ul><li>Please visit http://discover.tudelft.nl/ and let us know what you think! </li></ul>
