Developing Denmarks Next Generation Digital Library Work Underway
Developing Denmark's Next Generation Digital Library: Work Underway at Statsbiblioteket and DEFF Birte Christensen-Dalsgaard 1
Content • Introduction to: State and University Library and Denmark’s Electronic Research Library (DEFF) • Introduction to focus areas • Integrated search • Webservices – netmusic – infrastructure • Authentication Authorisation Infrastructure (AAI) • Open Access and Institutional Repositories (creation and preservation) • Research network/Grid/DEFF co-operation • Q&A 2
The State and University Library • National library (NL) – legal deposit library. The State & University Library receives a copy of all Danish publications, whether in printed or in digital format, – national newspaper collection, – national media archive (sound recordings, radio & tv) • National Loan Centre (OC) – Services for public libraries and small special libraries – Ethnic knowledge centre • University library (UL) – The State & University Library is the main library of the University of Aarhus. 3
Some numbers for 2004 • Stock – Books and periodicals (items) – Other materials – E-journals, titels • Meters • Bibliographic records 3. 527. 000 1. 445. 793 12. 339 109. 503 – Statsbiblioteket & departmental libraries 2. 310. 943 • Circulations/loans – Direct loans – Interlibrary loans 723. 111 441. 439 • Use of digital resources – periodicals – digital documents 938. 350 92. 400 4
DEFF: Denmark’s Electronic Research Library • DEFF is an organisational and technological partnership between research libraries • Co-financed by – The Ministry of Science, Technology and Innovation – The Ministry of Culture – The Ministry of Education • Annual budget of ~ 2, 3 mio. €
Organisation
History of Technological Change • First stage: New technologies are applied to existing processes (Do more of the same faster/cheaper) • Second stage: New technologies are integrated into existing process (Improving existing systems) • Third stage: New technologies are infused and diffused to create new processes and systems Apply Integrate Infuse & diffuse from: Mark Lawrence Kornbluh 7
Components towards the third stage • Presence in user environment – Availability (pervasive information) – Relevant services (e. g. user satisfaction) • New paradigms for search and presentation – Structured (SRU/SRW, OAI-PMH, Semantic web) – Unstructured (Google, …. , UIMA) • New paradigm for communication and publication • New Roles – different partnership – Service infrastructure (webservices, AAI, SOA, . . ) – Authenticity and permanent access • New economical models – Who pays for what, how 8

Libraries: Search and retrieve • Books & journals and catalogue cards • Books & journals and online catalogue • Books, journals & e-journals and online catalogue &databases with metadata – cross search Apply Integrate Infuse & diffuse 11

Background • Analysis of user behaviour and expectation: – Niels Ole Pors “Studerenden, Google og biblioteker”, July 2005 – “Perceptions of Libraries and Information Resources” OCLC, December 2005 – University og California: “Rethinking how we provide bibliographic Services”, Dec. 2005 – “Brugernes forventninger til det hybride bibliotek”, Marts 2006 13
Rethinking how we provide bibliographic Services • The University of California Libraries: Final Report Dec. 2005 • Users expectation to the Hybrid Library: Report March 2006 • The current Library Catalog is poorly designed for the tasks of finding, discovering, and selecting the growing set of available resources… it is best at locating and obtaining a known item • The library catalog plays no role in the selection process. It is used for locating known material. 14

Advantages of separating the library system from the search process: • From “precise query” to “relevance” • May use “standard” web technologies: – – Fast and efficient search algorithm Clustering analysis Introduce relevance ranking based on many parameters Advanced personalisation of query (e. g. based on history, training of “agent”) – … • Seamless service across different data resources – – structures <-> unstructures Non-library world can supply services (e. g. Amazon) Several document suppliers …… • Use the Traditional Library system to what it is good at – handling of Physical material 17
New development – short term • • • Did-You-Mean Basket Limit search (author, year) Alternative sorting (author, year, etc. ) Selected fields used for new searches 18
New development – long term • More resources (etss, e-books, DBC's netressourcer) • Include staff profiles in database • Clustering • Intelligent indeksing • Personalisation • Extra material (book covers, abstracts, …) • “SFX” 19
Information – where relevant: Portal to service 20
Legal music download from Danish Libraries. 21
Partners • Music Industry (IFPI), Danish Phonofile, Danish Copyright Organisations. • Department of Cultural Affairs. • State- and University library (Adm). • Consortium of large libraries. 22
Numbers • • Apr. 200. 000 tracks Download for 1 or 7 day(s) Microsoft DRM / 24 -7, 192 kbit files. Portal (www. netmusik. dk) and as a webservice (www. bibliotek. dk) • References for buying tracks • Administrative module for libraries • Subscription, tracks and statistics 23

Asynchronous Java. Script And XML AJAX • Possible to have constant update of information on users screen – (X)HTML & CSS – Client-side skripting (e. g. Java. Script) – Asynkronous exchange of data via XMLHttp. Request – Format of data: XML 26

AAI: The formation of a Danish In. Common: DK-AAI High level Cooperation between • Government bodies involved – Ministry of Science, Technology and Innovation – Ministry of Culture – Ministry of Education • Universities, other higher education, resarch institutions • DEFF incl. National libraries
DK-AAI - the scene Defining and organizing a common framework for identity and rights management administration within and between organizations for (higher) education, research and their e-resource providers
Institutional Repositories • OAi-based infrastructure for the Danish Research Database (DDF) • Support model to stimulate the creation of good and timely metadata to DDF • Initiative to standardise the exchange format: DDFMXD • Work on agreement on persistent identifiers • PU: RE now supports upload (Dspace, Fedora) – may extend to double upload • Steps towards preservation infrastructure
OAi. PMH
Open Access i Denmark – DEFF projects • Etss – a pilot project concerning e-migration of scientific journals – assistance to non-commercial publishers to online publishing and survival – evaluation and test of e-tool and workflow – the result is a guide to the process and the choice of tool – advocacy for Open Access – project website http: //deffetss. cvt. dk
Infuse/difuse – research infrastructure • Research Network – transmits information • Denmark’s Electronic Research Library – buys and disseminates information • Danish Centre for Grid Computing – processes information • and • Rector’s Conference project Digital Management
