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

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
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 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

“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

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

