Abstract

The UNIMARC format has become more widely used as a method of facilitating the international exchange of bibliographic data; due, in part, to a namber of projects funded by the European Union. Reviews the state of these projects as a report to a workshop on the UNIMARC format, Luxembourg, Sep 96. Projects described briefly include: UseMARCON; CoBRA UNIMARC; CoBRA AUTHOR; ONE; CHASE; DELICAT; and BIBLINK. Describes other initiatives related to to UNIMARC by IFLA and OCLC. Presents the main conclusions arising from the workshop addressing the areas of formats, authority control, character sets and electronic publications

Abstract

Secondary information, e.g. MARC based bibliographic records, comprises structured data for identifying, tagging, retrieving and management of primary documents. SGML, the standard format for coding content and structure of primary documents, was introduced in 1986 as a publishing tool but is now being applied to bibliographic records. SGML now comprises standard definitions (DTD) for books, serials, articles and mathematical formulae. A simplified version (HTML) is used for Web pages. Pilot projects to develop SGML as a standard for bibliographic exchange include the Dublin Core, listing 13 descriptive elements for Internet documents; the French GRISELI programme using SGML for exchanging grey literature and US experiments on reformatting USMARC for use with SGML-based records

Abstract

Authority records complement bibliographic records, providing cataloguers with essential subject heading and related information. At present there is no international format standard comparable to ISBD for bibliographic records, though IFLA and the International Archives Council have set up working groups. The essential data form comprises of subject heading, structure, homonyms, with supplementary supporting information. In France MARC formats are most widely used, e.g. UNIMARC(A) for authority records and (B) for bibliographic. The National Library (BNF) is introducing new cataloguing software based on the reorganisation of its authotity files, using integrated INTERMARC. As an experiments, readers will for the first time have access to authority files, thus enriching, completing and clarifying the bibliographic records

Abstract

The French National Library (NBF) has developed 2 new versions of INTERMARC, (A) and (B), to standardise cataloguing procedures and enrich bibliographic description and access. The bibliographic description format (B) accords with existing ISBD and can be used for all types of documents, allowing inclusion of specific characteristics and addition of new links. The format for editing records (A) eliminates redundancies and enriches links between fields. Both will be used as reference formats in the new Information System

Abstract

The Bayerische Staatsbibliothek acting on behalf of the Consortium of European Research Libraries (CERL) was responsible for the preparation of this report under a contract agreed with the Commission of the European Communities Directorate General XIII as part of their Libraries Programme. The report considers the feasibility of the application of UNIMARC to multinational databases, and was based on a comparison of machine-readable bibliographic records in the UNIMARC format from 6 different national sources. Some are conversions from other formats, while others are 'native' UNIMARC records. The records are of books of the hand press period, that is, from the time of Gutenberg to about 1830

Abstract

This article explores recent discussions about appropriate mark-up conventions for library information intended for use on the World Wide Web. In particular, the question of whether the MARC 21 format will continue to be useful and whether the time is right for a full-fledged conversion effort to XML is explored. The author concludes that the MARC format will be relevant well into the future, and its use will not hamper access to bibliographic information via the web. Early XML exploratory efforts carried out at the Stanford University's Lane Medical Library are reported on. Although these efforts are a promising start, much more consultation and investigation is needed to arrive at broadly acceptable standards for XML library information encoding and retrieval.

Abstract

Evaluates current research into bibliographic relationships sparked off by B.B. Tillett's taxonomy of bibliographic relationships (LRTS 35(1991) no.4, S.393-405) and R.P. Smiraglia's taxonomy of the derivative bibliographic relationship (PhD dissertation, Chicago Univ., Graduate Library School, 1992). These researches provide the context for a discussion of recent research and standards work. Reevaluates research on the sequential relationship drawn from work conducted on periodicals and the implications of that research is applied to cataloguing system design. Evaluates the conceptual designs proposed by researchers such as G.H. Leazer and M. Gorman's and uses them in a critique of the USMARC format for bibliographic description

Abstract

The MARC standard for representing catalogue records and the Z39.50 standard for locating and retrieving them have facilitated interoperability in the library domain for more than a decade. With the increasing ubiquity of XML, these standards are being superseded by MARCXML and MarcXchange for record representation and SRW/U for searching and retrieval. Service providers moving from the older standards to the newer generally need to support both old and new forms during the transition period. YAZ Proxy uses a novel approach to provide SRW/MARCXML access to the Library of Congress catalogue, by translating requests into Z39.50 and querying the older system directly. As a fringe benefit, it also greatly accelerates Z39.50 access.

Abstract

The Europeana Data Model (EDM) is a new approach towards structuring and representing data delivered to Europeana by the various contributing cultural heritage institutions. The model aims at greater expressivity and flexibility in comparison to the current Europeana Semantic Elements (ESE), which it is destined to replace. The design principles underlying the EDM are based on the core principles and best practices of the Semantic Web and Linked Data efforts to which Europeana wants to contribute. The model itself builds upon established standards like RDF(S), OAI-ORE, SKOS, and Dublin Core. It acts as a common top-level ontology which retains original data models and information perspectives while at the same time enabling interoperability. The paper elaborates on the aforementioned aspects and the design principles which drove the development of the EDM.

Abstract

SKOS Core provides a model for expressing the basic structure and content of concept schemes such as thesauri, classification schemes, subject heading lists, taxonomies, 'folksonomies', other types of controlled vocabulary, and also concept schemes embedded in glossaries and terminologies. The SKOS Core Vocabulary is an application of the Resource Description Framework (RDF), that can be used to express a concept scheme as an RDF graph. Using RDF allows data to be linked to and/or merged with other data, enabling data sources to be distributed across the web, but still be meaningfully composed and integrated. This document is a guide using the SKOS Core Vocabulary, for readers who already have a basic understanding of RDF concepts. This edition of the SKOS Core Guide [SKOS Core Guide] is a W3C Public Working Draft. It is the authoritative guide to recommended usage of the SKOS Core Vocabulary at the time of publication.
