A Service For the Nation Ari Rouvari 16. - 17.8.2004 Pedase, Vihterpalu
TOPICS Information retrieval portals Services Nelli, National Electronic Library Interface The Finnish consortia model A little demo Usability Interoperability Development projects
INFORMATION RETRIEVAL PORTALS WHY? a lot of heterogenius resources For example in Finland (FinELib) –14 500 ejournals –Over 175 databases –A lot of library catalogues Library systems - we need something more How to organize How to use
DEFINITION by Marc Carden A common interface that allows users to access library-owned resources and library- accessible resources.
DEFINITION BY ELAG A LIBRARY portal is an application which allows one-stop-shop access/searching and discovery via a unified single-point interface to organized heterogeneous resources and enabling services to a pre-defined community (users)
DEFINITION BY JISC Technically, a portal is a network service that brings together content from diverse distributed resources using technologies such as cross searching, harvesting, and alerting, and collates this into an aggregated form for presentation to the user, usually via a website
Services and characters organizing metasearching display authentication authorization tailoring personalization OpenURL linking Standard interfaces
Visions and aims one-stop-shop single-sign-on One search, all services easy to use Centralized maintaining & management One server for the entire nation Local user interfaces tailoring Local services Collaborative development of services Keep it simple stupid!
USABILITY CASE STUDIES Amsterdam university Two test groups Loughborough University, (Stubbings and Hamblin,2004). promising trend in the use of libraries’ information the use of databases rose by 609% over the previous year. Zetoc rose by 1,385% & SportDiscus by 1,207%. not cross-searchable saw an increase in usage, for example, ICEA went up by 225% and ANES by 36%.
Nelli-portal in consortia environment Centralized tasks: co-ordinating the project implementing / maintaining updating SFX/Metalib SFX activiting instructions configuration files (Metalib) descriptions of resources user interfaces (multi- languages) Development of services Local tasks: Authentication Activating SFX-targets Copying of conf. Files Copying of descriptions Local tailoring Local services training
Shibboleth authentication Nelli-portal Shibboleth target site = proxy Home campus 3. Auth. OK 1. select home campus 2. Auth. starts Shibboleth origin site login & password LDAP directory 4. Attribute request 5. Response attr: email address remote authentication CGI-hook
Shibboleth authorization (vision) Nelli-portal Home campus SFX-target: ejournal database Attribute Authority Authentication Handle service SFX Resolver Attribute query Attribute resonse / pass on attributes cross-search target dbs
”THE TRIANGLE” CONSIST OF 1. The portal (Metalib/SFX) user interface / Authentication metasearch linking resolver & access restriction 2. Library system (Voyager) description metadata 3. Document archive(Encompass) technical metadata repository Standard-base, standard interfaces openURL, Z39.50, Zing, Marc Portal library system Document archive Z39.50ZING OpenURL
one scenario: digital music collection (legal deposit copies) Search interface Nelli-portal Target database Linnea-library system Z39.50 records access control SFX-resolver digital archive digital objects special metadata restrict access by collections OpenUrl
THE RESOURCE MAP OF FINNISH ACADEMIC LIBRARIES Australian Libraries Gateway Scottish Collections Network, SCONE Describe DCCD application Evaluate Conspectus method
USER INTERFACE FETISHISM Nelli-portal: Local interfaces Regional interfaces National interfaces Library system OPACs Document archive Customer oriented way More is better?
INTEROPERABILITY WITH Institutional portals /university portals Integration with elearning systems Instructors Define reading list Define searches Define resources End users Use reading list Use pre-defined searches Goal: Anywhere, any time
Technical environment Sun Fire 4800 and Solaris-OS Software: Apache, MySQL, Oracle Technical maintenance (patches in OS, all the backups) by CSC, the Finnish IT center for science Connecting to the Funet Backbone Network
Nelli organization Nelli staff Ari, co-ordinating Tiina, technical issues mr/mrs X, services The Portal team (9) local project managers (20) local trainers (10) document archive LS- team Portal team The Triangle team
