Your OPACInhospitable

Information discovery in libraries

Information discovery on the web

Today’s presentation
Our experience with a new discovery model• Based on aggregating metadata from a variety of
sources• What happens when you actually try to use that
metadata for discovery• What other challenges emerge
![Page 5: Escape from Alcatraz Freeing the OPAC from traditional constraints Lloyd Sokvitne Senior Manager (Digital Strategies) State Library of Tasmania](https://reader035.fdocuments.us/reader035/viewer/2022062504/5a4d1b1c7f8b9ab059993bd5/html5/thumbnails/5.jpg)
Providing a single search
• Disillusioned with federated searching• Aggregating metadata as preferred
approach– NLA, OAI, and other successes– Include both Marc and Non-Marc Metadata– Its our own data anyway
• Want control over outcomes
![Page 6: Escape from Alcatraz Freeing the OPAC from traditional constraints Lloyd Sokvitne Senior Manager (Digital Strategies) State Library of Tasmania](https://reader035.fdocuments.us/reader035/viewer/2022062504/5a4d1b1c7f8b9ab059993bd5/html5/thumbnails/6.jpg)
Moving outside the ILMS
• easier web friendly deliverables• applications adaptable/flexible• client-orientated outcomes
– discovery services– interactive web2.0 developments
• We are seeing a growing need to be able to interact with the ILS in various ways, so that some functionality can be placed in another interface – Lorcan Dempsey, 20 Jan 20, 2006

A 3-tier architecture
Uncoupling the data from the applications that create itProviding client services that are not defined by data containersThe data should be usable by any or all applications above it
Client Service

Aggregated Metadata Information System (AMIS)
• Proof of concept developed– 500,000 OPAC Marc records exported
• Converted to a common XML format– Other records converted (images, etc)– XML records were indexed using Lucene
• 5 hrs on a desktop pc– Query screen written– All up – 2-3 days effort

Also able to provide facets for format, genre, location, subject, etc

Prototype results
• Proved concept– Technology part is easy– Tender process almost over, market
response good– Identified that we will need to improve the
actual data• How did we want our portal to work?
![Page 14: Escape from Alcatraz Freeing the OPAC from traditional constraints Lloyd Sokvitne Senior Manager (Digital Strategies) State Library of Tasmania](https://reader035.fdocuments.us/reader035/viewer/2022062504/5a4d1b1c7f8b9ab059993bd5/html5/thumbnails/14.jpg)
To match user behaviour
• Offline behaviour– browsing• Ignored in virtually every library system• facets: open-display of content, and refining
• Online behaviour – satisficing/ranking• Ignored in virtually every library system• Ranking as the key determinant
• User interaction – ratings, reviews, etc
Now possible because we are outside the ILMS
![Page 15: Escape from Alcatraz Freeing the OPAC from traditional constraints Lloyd Sokvitne Senior Manager (Digital Strategies) State Library of Tasmania](https://reader035.fdocuments.us/reader035/viewer/2022062504/5a4d1b1c7f8b9ab059993bd5/html5/thumbnails/15.jpg)
Aggregator metadata
• Need appropriate metadata– Valid only if useful to actual searching as performed by our
clients• Data mining
– frequency of use, number of reservations, etc• Data sharing
– reviews, commentaries, tables of contents, etc• Data creation
– Libraries – adding more information, discarding unused data– Users – adding ratings, reviews, etc
![Page 16: Escape from Alcatraz Freeing the OPAC from traditional constraints Lloyd Sokvitne Senior Manager (Digital Strategies) State Library of Tasmania](https://reader035.fdocuments.us/reader035/viewer/2022062504/5a4d1b1c7f8b9ab059993bd5/html5/thumbnails/16.jpg)
Next steps
• Client interaction modules – reviews, – ratings, – wikis, – RSS, – Blogs, etc
• will be added progressively
![Page 17: Escape from Alcatraz Freeing the OPAC from traditional constraints Lloyd Sokvitne Senior Manager (Digital Strategies) State Library of Tasmania](https://reader035.fdocuments.us/reader035/viewer/2022062504/5a4d1b1c7f8b9ab059993bd5/html5/thumbnails/17.jpg)
Data is just a commodity
• ILMS integration occurred for efficiency– data storage, consistency, reuse
• efficiency now possible in other ways– moving data in large quantities is easy– accessing data in real time is easy
An OPAC no longer needs to be something provided by an ILMS
![Page 18: Escape from Alcatraz Freeing the OPAC from traditional constraints Lloyd Sokvitne Senior Manager (Digital Strategies) State Library of Tasmania](https://reader035.fdocuments.us/reader035/viewer/2022062504/5a4d1b1c7f8b9ab059993bd5/html5/thumbnails/18.jpg)
Conclusions
• AMIS – technically easy, doable• Need the right metadata to succeed• Need the right search interface
– not just a slightly modified OPAC– the design is up to us
• (there couldn’t be a better time to be a librarian)

A connected OPAC
Easy
Relevant
Busy and used
The new Alcatraz
