DESCRIPTION

In this presentation Olaf Janssen - Project Manager at The European Library - introduces the national libraries of Europe. He outlines the history, organisational and technical foundations of The European Library, the collaborative platform and website of the 48 national libraries of Europe. He outlines the benefits of collaboration between these institutions and explains how The European Library has established technical and metadata interoperability across Europe. He discusses the ingredients for a successful European Digital Library (to be called Europeana) and assess the current state of play and the remaining challenges. The conclusions are: * Common and open standards for access and interoperability are essential for a European Digital Library * The European Library is the forerunner * Building a European Digital Library is a much a political & social game as it is a technological * The willingness to collaborate is key!! I held this talk at the Library of Congress, Washington DC, USA, on 03-04-2007

TheEuropeanLibrary.org = - service of all 47 European national libraries - to provide access to their - catalogues & digital collections - via 1 central multi-lingual web interface - (= portal) What is The European Library? 2.1 Introduction to The European Library 8. www.TheEuropeanLibrary.org 9. Background Origin in 2001: TELproject: 2.5y feasibility study funded by EU and led by The British Library Intended to create operational service from start, so business plan was part of TELproject The European Library is live since 17 March 2005 (beta) Currently owned by CENL, funded by the national libraries (NOT EU) Development + maintenance by The European Library Office (Netherlands 9 FTE) 2.1 Introduction to The European Library 10. Two types of participants Full Participants : libraries whose catalogues and digital collections are included in The European Library portal (23) Basic Participants : catalogues and digital collections not yet included (24) 2.1 Introduction to The European Library 11. Current + future Full Participants Now : 250+ collections from 23 national libraries: Austria, UK, Croatia, Denmark, Estonia, Finland, France, Germany, Italy(2x), Latvia, Netherlands, Portugal, Serbia, Slovenia, Switzerland, Poland, Cyprus, Malta, Lithuania, Hungary, Czech Republic, Slovakia End 2007 : 330 collections from 34 libraries Spain, Liechtenstein, Luxembourg, Norway, Sweden, Greece, Iceland, Ireland, Belgium, Bulgaria & Roumenia Mid 2009 : 400 collections from 44 libraries Russia (2x), former Sovjet republics, Albania, Bosnia.. 2.1 Introduction to The European Library 12. Whats Good about The European Library For end-users Have integrated access to catalogues & digital collections of national libraries of Europe Quality-controlled deep web resources 250+ collections, 2.0M digital objects and 50M metadata records For the national libraries International showcase for collections Wider access to their collections & content Combined political mass greater marketing and negotiation power. Platform for collaboration 2.1 Introduction to The European Library 13. 2.1 Introduction 2.2 The European Library relies on common standards A. Access protocols B. Metadata C. Collection descriptions D. Multi-linguality 2. The European Library 14. The European Library = hybrid portal = federated search tool Overall goal of The European Library = COLLABORATION Low implementation barrier for libraries is key!! Different libraries demand different access protocols to access their collections TEL infrastructure uses 4 protocols : OAI-PMH, Z39.50, SRU, OpenURL The European Library portal queries 1 central index (90 harvested collections, OAI-PMH) 160 remote databases (Z39.50 & SRU) 2.2.A Access protocols in The European Library 15. Techniques / protocols used (I) 1. OAI-PMH (Open Archives Initiative Protocol for Metadata Harvesting) OAI enabled collections have their metadata harvested, indexed and stored in TEL central index Queries in these collections are queries in TEL central index 2.2.A Access protocols in The European Library 16. Harvesting via OAI-PMH TEL server(s) OAI-PMH collection TEL central index (90 coll.) OAI-PMH harvester OAI-PMH collection OAI-PMH collection 17. TEL server(s) TEL central index OAI-PMH OAI-PMH collection OAI-PMH collection OAI-PMH collection Harvesting via OAI-PMH 18. 2. SRU (Search Retrieve via Url) SRU enabled collections are queried on-the-fly using this protocol Direct communication with TEL-portal 3. Z39.50 Z39.50 enabled collections are queried on-the-fly via a Z39.50/SRU gateway Z39.50/SRU gateway = translator (housed on TEL server) Translates SRU requests to Z39.50 session vv. Translates TEL portal search language (CQL) into search language of Z39.50 target. Converts record format of Z39.50 target into TEL metadata format Does character set conversions (Unicode) 2.2.A Access protocols in The European Library Techniques / protocols used (II) 19. 4. OpenURL for linking to external webservices 2.2.A Access protocols in The European Library Techniques / protocols used (III) 20. Loading the TEL-portal TEL server(s) central index web server http://www.theeuropeanlibrary.org TEL portal only speaks & understands SRU 21. Loading translations and collections (I) TEL server(s) central index web server http://www.theeuropeanlibrary.org 22. Loading translations and collections (II) translations.xml : all translations needed to display the interface in the chosen language (20) collections.xml : all collection descriptions needed to execute searches across the different collections translations.xml collections.xml SRU Z39.50 23. A. Search/retrieve in TEL central index via SRU TEL server(s) web server query OAI-harvested metadata = TEL central index SRUSRU TEL portal only speaks & understands SRU 24. B. Search/retrieve in SRU enabled remote collection TEL server(s) web server query central index SRU SRU TEL portal only speaks & understands SRU 25. TEL server(s) web server query central index SRU Z39.50/SRU gateway SRU Z39.50 TEL portal only speaks & understands SRU C. Search/retrieve in Z39.50 enabled remote collection 26. Search/retrieve all at once! TEL server(s) web server query central index SRU SRU Z39.50/SRU gateway SRU Z39.50 SRU 27. 2.1 Introduction 2.2 The European Library relies on common standards A.
