  10. FRBR • Functional Requirements for Bibliographic Records (from IFLA) • A conceptual framework: • Work (Hamlet: Prince of Denmark) • Expression (a Russian translation) • Manifestation (third printing) • Item (copy 2) • Records for manifestations (presently separate) can be collapsed into one item at the work or expression level

  11. OCLC — Curiouser

  12. Metasearching • Searching two or more separate sources simultaneously • Often includes: • Merged and deduplicated search results • Ability to save/email/download citations • Can include: • Relevance ranking

  13. Why Metasearching? • Only librarians like to search, everyone else prefers to find • Libraries increasingly offer a staggering array of resources • Google has increased user expectations and their impatience • New technologies are offering a possible solution

  14. Benefits • For users: one place to search, no need to learn multiple interfaces, other services more easily integrated • For staff: decreased need to lead users to individual databases and teach multiple interfaces • What this replaces: possibly a subject guide to databases, but does not replace any software component libraries currently have

  15. Web 2.0

  16. Web 2.0 • Web 1.0: client sends request, server sends HTML page, connection dropped, client renders page • Web 2.0: a set of technologies that enables grabbing information dynamically from various sources and presenting it in a highly interactive way • Technologies involved: • HTTP, HTML, etc. • Web Services • AJAX

  17. Web Services: SOAP or REST • A method to exchange structured information (i.e., XML) between applications: • SOAP: request is packaged up as an XML file; or, • REST: request is packaged up as a URL with parameters: http://oai.cdlib.org/?verb=Identify • The response is always XML

  18. Google Maps

  19. Ajax • A particular flavor of Web Services that uses Javascript, XHTML, and CSS in addition to XML • Provides highly interactive interfaces without web page reloads • Google Maps prime example, but rapid uptake

  20. OCLC — Live Search Demo at http://phoenix.orhost.org/

  21. “Mashups” • Using other people’s data in a presentation you control • Uses Ajax technologies • The opposite of silo systems: systems that can mix and match data from multiple sources you do not control

  22. Collaborative Filtering

  23. Collaborative Filtering • Links • Del.icio.us • Unalog • Music • Last.fm (Audioscrobbler) • Books • Amazon’s lists • Movies • MovieLens • Photos • Flickr
