Escape from Alcatraz Freeing the OPAC from traditional constraints Lloyd Sokvitne Senior Manager (Digital Strategies) State Library of Tasmania lloyd.sokvitne@education.tas.gov.au

Your OPAC Inhospitable Distant Uninviting Information discovery in libraries
3
Information discovery on the web Inviting Friendly Easy
4
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
5
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
6
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
7
A 3-tier architecture Uncoupling the data from the applications that create it Providing client services that are not defined by data containers The data should be usable by any or all applications above it Client Service Data Storage Applications MODULES 1.client interaction 2.acquisitions 3.indexing 4.searching 5.circulation 6.DOM
8
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
9
Screenshot Fast : Able to add new features : Able to participate in web environment
10
Screenshot Live query works for live data
12
Also able to provide facets for format, genre, location, subject, etc
13
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?
14
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
15
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
16
Next steps Client interaction modules –reviews, –ratings, –wikis, –RSS, –Blogs, etc will be added progressively
17
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
18
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
