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 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: http://oai.cdlib.org/?verb=Identify 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 OCLC — Live Search Demo at http://phoenix.orhost.org/ “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 Collaborative Filtering Collaborative Filtering Links Del.icio.us Unalog Music Last.fm (Audioscrobbler) Books Amazon’s lists Movies MovieLens Photos Flickr Flickr, unalog, What to Do Start and end with your clientele Learn the technologies available to you that are appropriate to your mission Imaginatively apply those technologies to serve the unique needs of your users Provide easy access to what they want, how and when they want it Market those services well Rinse and repeat
