Interoperability and Standards for Bibliographic Applications Poul Henrik Jørgensen phj@dbc.dk Danish Library Centre www.dbc.dk Telematics for Libraries Nov. 1999
Overview • Bibliographic IT Standards • Standardisation Activities • Profiling for Interoperability • Implementation Clusters • Common Toolkits • Current Issues • Future Developments • Achievements with European perspectives Poul Henrik Jørgensen, phj@dbc.dk
Bibliographic IT Standards • Z39.50 Search and Retrieval • ISO ILL Interlibrary Loans • EDI Electronic Data Interchange • ISO 8459 Data Elements • Z39.70 (or Z39.81?) Circulation & ILL • GEDI Electronic Document Delivery • Metadata, Dublin Core & RDF Poul Henrik Jørgensen, phj@dbc.dk
Standardisation Activities • ISO TC 46 SC4 • ZIG. Z39.50 Implementers Group • IPIG. ILL Protocol Implementers Group • EDItEUR. European Book trade EDI Group • IFLA • Dublin Core • W3C Web Standards Poul Henrik Jørgensen, phj@dbc.dk
Z39.50v3-1995 = ISO 23950 • Standard for on-line communication between systems – no user-interface aspects • Defines transmission methods, abstract services and transaction formats • Independent of implementation details in associated systems • Services includes Search and Retrieval, Update, Item Ordering and others Poul Henrik Jørgensen, phj@dbc.dk
Standard Profiles • Agreements about how to implement a communications standard in practice • Which of the available services and transactions to support – and how? • Z39.50 Profiles specify Search attributes, Record formats, Character sets and Extended services etc. Poul Henrik Jørgensen, phj@dbc.dk
Common Z39.50 Profiles • ATS-1: Author Title Subject • GILS: US Government Information • CIMI & Aquarelle: Museums & Archives • CoBRA & EFILA: Common European National Library (CENL) • Bath: Search, Holdings, Cross-domain • ONE-2: Bath + Update, ILL, EDD Poul Henrik Jørgensen, phj@dbc.dk
Z39.50 Systems Architecture Z39.50 Client System Z39.50 Server System SR Services Database Explain Services Database Extended Services Database Z39.50 Client User Interface Z39.50 Origin Services Search-Retrieve Services Explain Services Extended Services Z39.50 Target Protocol Machine Z39.50 Origin Protocol Machine Poul Henrik Jørgensen, phj@dbc.dk
Z39.50 Implementation Clusters • SOCKER: Origin Protocol Machine (PM) & different Client architectures • ARCA: Server Toolkit and Client • ONE: General PM, Utilities, Client, Gateway and Servers • UNIVERSE: Virtual Union Catalogues • MALVINE: Servers & Clients Poul Henrik Jørgensen, phj@dbc.dk
Dublin Core Metadata Initiative • Elise II: Image Databases • Euler: Mathematical Materials • Malvine: Letters & Manuscripts • Biblink: Information about Electronic Materials • IndoReg: Internet Documents as part of Danish National Bibliography Poul Henrik Jørgensen, phj@dbc.dk
Current Issues • ZIG Holdings Data Schema • MARC Formats. USMarc & UniMARC? • Character Set handling • ISO ILL. Z39.50/ILL or E-mail, XML? • Circulation Standards. 3M, Z39.81? • Electronic Document Delivery. GEDI? • EDI. EDIfACT or XML? Poul Henrik Jørgensen, phj@dbc.dk
Future Developments • Integrated Services, e.g. Z39.50 & ILL • XML and related W3C standards • ZHTTP: Z39.50, HTTP and XER • Resource Definition Framework, RDF • IFLA Functional Requirements • Cross-domain access • Authentication and Control Poul Henrik Jørgensen, phj@dbc.dk
Achievements in Interoperability • Professional Networks • Impact on Standardisation • Internationally recognised Toolkits • State-of-the-art Servers and Clients • New Integrated Services • Market for Interchangeable Systems Components Poul Henrik Jørgensen, phj@dbc.dk
