Agenda Better Search Systems Web 2.0 Collaborative Filtering What to Do

Better Search Systems

Better Library Catalogs Better exposure of controlled vocabularies Better browsing opportunities Enhanced records Relevance ranking Recommendations Grouped displays Linkages to additional content/info/services

CSU San Marcos X9

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

OCLC — Curiouser

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

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

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

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

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: The response is always XML

Google Maps

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

“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
