Abstract

T.1: Today's thesauri are mostly electronic tools, having moved on from the paper-based era when thesaurus standards were first developed. They are built and maintained with the support of software and need to integrate with other software, such as search engines and content management systems. Whereas in the past thesauri were designed for information professionals trained in indexing and searching, today there is a demand for vocabularies that untrained users will find to be intuitive. ISO 25964 makes the transition needed for the world of electronic information management. However, part 1 retains the assumption that human intellect is usually involved in the selection of indexing terms and in the selection of search terms. If both the indexer and the searcher are guided to choose the same term for the same concept, then relevant documents will be retrieved. This is the main principle underlying thesaurus design, even though a thesaurus built for human users may also be applied in situations where computers make the choices. Efficient exchange of data is a vital component of thesaurus management and exploitation. Hence the inclusion in this standard of recommendations for exchange formats and protocols. Adoption of these will facilitate interoperability between thesaurus management systems and the other computer applications, such as indexing and retrieval systems, that will utilize the data. Thesauri are typically used in post-coordinate retrieval systems, but may also be applied to hierarchical directories, pre-coordinate indexes and classification systems. Increasingly, thesaurus applications need to mesh with others, such as automatic categorization schemes, free-text search systems, etc. Part 2 of ISO 25964 describes additional types of structured vocabulary and gives recommendations to enable interoperation of the vocabularies at all stages of the information storage and retrieval process.
T.2: The ability to identify and locate relevant information among vast collections and other resources is a major and pressing challenge today. Several different types of vocabulary are in use for this purpose. Some of the most widely used vocabularies were designed a hundred years ago and have been evolving steadily. A different generation of vocabularies is now emerging, designed to exploit the electronic media more effectively. A good understanding of the previous generation is still essential for effective access to collections indexed with them. An important object of ISO 25964 as a whole is to support data exchange and other forms of interoperability in circumstances in which more than one structured vocabulary is applied within one retrieval system or network. Sometimes one vocabulary has to be mapped to another, and it is important to understand both the potential and the limitations of such mappings. In other systems, a thesaurus is mapped to a classification scheme, or an ontology to a thesaurus. Comprehensive interoperability needs to cover the whole range of vocabulary types, whether young or old. Concepts in different vocabularies are related only in that they have the same or similar meaning. However, the meaning can be found in a number of different aspects within each particular type of structured vocabulary: - within terms or captions selected in different languages; - in the notation assigned indicating a place within a larger hierarchy; - in the definition, scope notes, history notes and other notes that explain the significance of that concept; and - in explicit relationships to other concepts or entities within the same vocabulary. In order to create mappings from one structured vocabulary to another it is first necessary to understand, within the context of each different type of structured vocabulary, the significance and relative importance of each of the different elements in defining the meaning of that particular concept. ISO 25964-1 describes the key characteristics of thesauri along with additional advice on best practice. ISO 25964-2 focuses on other types of vocabulary and does not attempt to cover all aspects of good practice. It concentrates on those aspects which need to be understood if one of the vocabularies is to work effectively alongside one or more of the others. Recognizing that a new standard cannot be applied to some existing vocabularies, this part of ISO 25964 provides informative description alongside the recommendations, the aim of which is to enable users and system developers to interpret and implement the existing vocabularies effectively. The remainder of ISO 25964-2 deals with the principles and practicalities of establishing mappings between vocabularies.

Abstract

ISO 25964-2:2013 is applicable to thesauri and other types of vocabulary that are commonly used for information retrieval. It describes, compares and contrasts the elements and features of these vocabularies that are implicated when interoperability is needed. It gives recommendations for the establishment and maintenance of mappings between multiple thesauri, or between thesauri and other types of vocabularies.

Abstract

This Standard presents guidelines and conventions for the contents, display, construction, testing, maintenance, and management of monolingual controlled vocabularies. This Standard focuses on controlled vocabularies that are used for the representation of content objects in knowledge organization systems including lists, synonym rings, taxonomies, and thesauri. This Standard should be regarded as a set of recommendations based on preferred techniques and procedures. Optional procedures are, however, sometimes described, e.g., for the display of terms in a controlled vocabulary. The primary purpose of vocabulary control is to achieve consistency in the description of content objects and to facilitate retrieval. Vocabulary control is accomplished by three principal methods: defining the scope, or meaning, of terms; using the equivalence relationship to link synonymous and nearly synonymous terms; and distinguishing among homographs.

Abstract

SKOS (Simple Knowledge Organisation System) provides a model for expressing the basic structure and content of concept schemes such as thesauri, classification schemes, subject heading lists, taxonomies, folksonomies, and other types of controlled vocabulary. As an application of the Resource Description Framework (RDF) SKOS allows concepts to be documented, linked and merged with other data, while still being composed, integrated and published on the World Wide Web. This document is an implementors guide for those who would like to represent their concept scheme using SKOS. In basic SKOS, conceptual resources (concepts) can be identified using URIs, labelled with strings in one or more natural languages, documented with various types of notes, semantically related to each other in informal hierarchies and association networks, and aggregated into distinct concept schemes. In advanced SKOS, conceptual resources can be mapped to conceptual resources in other schemes and grouped into labelled or ordered collections. Concept labels can also be related to each other. Finally, the SKOS vocabulary itself can be extended to suit the needs of particular communities of practice.

Abstract

Am Anfang war das Wort. Sehr viel später erfand ein gewisser Herr Gutenberg ein Handgießinstrument zur Herstellung von Drucktypen. Und was sich daraus entwickelte, ist bekannt: Die moderne Informations- und Kommunikationsgesellschaft, deren Dynamik nicht zuletzt von der Effektivität der Daten-, Dokumenten- und Schriftgutverwaltung abhängt. Beim DIN-Taschenbuch 343 Bibliotheks- und Dokumentationswesen handelt es sich um ein Normenkompendium, das genau diese Verfahren aufgreift: Es stellt der interessierten Fachöffentlichkeit insgesamt 22 nationale und internationale Normen der Bereiche "Gestaltung und Erschließung von Dokumenten", "Bibliotheksmanagement", "Codierungs- und Nummerungssysteme" sowie "Bestandserhaltung in Archiven und Bibliotheken" vor. Die Auswahl der Normen verdeutlicht zweierlei: Zum einen den Einfluss der sich ständig weiterentwickelnden und dabei konvergierenden Technologien, der u.a. das Publizieren und die Datenrecherche beeinflusst. Zum zweiten die Notwendigkeit, neue Anforderungen zu berücksichtigen, die sich aus dem stetig zunehmenden internationalen Datenaustausch ergeben. Das DIN-Taschenbuch verschafft einen genauen Überblick über den Zusammenhang zwischen einschlägigen DIN- und ISO-Normen und klärt über Namencodes von Ländern und deren Untereinheiten auf (DIN ISO 3166-2:2001). Komplettiert wird das Werk durch den vollständigen Abdruck des DINFachberichts 13 "Bau- und Nutzungplanung von wissenschaftlichen Bibliotheken". Dort werden Bibliotheken als Servicezentren verstanden, die zunehmend digitalisierte Informationsquellen bereit stellen.

Rez. in: ABI-Technik 21(2002) H.3, S.294-295 (K. Weishaupt); "Im Deutschen Institut für Normung ist der Normenausschuss Bibliotheks- und Dokumentationswesen (NABD) verantwortlich für die nationale Normung für das Erstellen, Publizieren, Erschließen, Erhalten, Wiederauffinden, Vermitteln und die Nutzung von Dokumenten, Daten und Schriftgut für die Bereiche Archiv-, Bibliotheks, Dokumentations-, Museumsund Verlagswesen. Mit dem neuen DIN-Taschenbuch will er einen Überblick über die DIN-Normen geben, die in den letzten Jahren auf internationaler Ebene unter aktiver deutscher Mitarbeit veröffentlicht, dann als DIN-Normen übernommen worden sind und die den veränderten Anforderungen der Informations- und Kommunikationsgesellschaft Rechnung tragen - so die eigenen Angaben des Ausschusses im Vorwort (S. XI). Vor dem Hintergrund dieses recht offen formulierten Anspruches kommt es zu einer Zusammenstellung von 22 Normen, die auf den ersten Blick recht bunt gemischt wirkt: Abgedruckt sind Normen zur Erstellung und Weiterentwicklung von Thesauri, zu Titelangaben von Dokumenten, Kürzungs- und Transliterationsregeln, Sortierregeln, Abschnittsnummerierungen, Ländernamen, zur ISBN, ISSN sowie den Standardnummern ISMN und ISWC für Musikalien, zu Leistungsindikatoren für Bibliotheken und zu Lebensdauer-Klassen von Papier und Karton, Anforderungen an die Aufbewahrung von Archiv- und Bibliotheksgut und zur Alterungsbeständigkeit von Schriften. Der DIN-Fachbericht "Bau- und Nutzungsplanung von wissenschaftlichen Bibliotheken" rundet das Werk ab. Negativ ausgedrückt: Es wird niemanden geben, der für seinen beruflichen Alltag all diese Normen benötigt. Die positive Sicht: Das DIN-Taschenbuch deckt so viele Themen ab, dass der Kreis der Interessierten recht groß sein dürfte. Auf alle Fälle ist beeindruckend, zu wie vielen Themen aus den Bereich des Bibliotheks- und Dokumentationswesens es Normen gibt; vermutlich ist deren Existenz nicht einmal der Fachöffentlichkeit in vollem Umfang bekannt. Ein solches Beispiel ist DIN 1505, Teil 2: "Titelangaben von Dokumenten: Zitierregeln"; diese Norm wendet sich "an Autoren, Verleger und Redakteure und soll für Literaturzusammenstellungen, für Literaturverzeichnisse am Ende einer Schrift bzw. eines Beitrags, im Kontext oder in Fußnoten benutzt werden" (S. 38). Damit ist sie praktisch für alle relevant, die wissenschaftlich arbeiten und Texte schreiben - aber kaum jemand kennt diese Norm! Viele Zeitschriften und Fachgesellschaften haben ihre eigenen Regeln, nach denen zitiert werden soll. Im Institut Arbeit und Technik in Gelsenkirchen ist vor einigen Jahren mit Förderung der Deutschen Forschungsgemeinschaft die Software LibLink entwickelt worden, mit der aus MAB-Daten, die aus einem Bibliothekskatalog exportiert worden waren, automatisiert Literaturverzeichnisse für wissenschaftliche Texte erstellt werden sollten.
Das erwies sich als äußerst schwierig, da es erstens keinen allgemein anerkannten Standard fürs Zitieren gibt und zweitens zwischen Literaturverzeichnissen wissenschaftlicher Texte und Bibliotheksdaten Diskrepanzen bestehen, die nicht automatisiert bereinigt werden können. Wie sich im Laufe des Projektes gezeigt hat, gilt das auch für Literaturverzeichnisse, die nach DIN 1505 gestaltet werden, obwohl diese Norm im Zusammenarbeit mit der Deutschen Bibliothek und dokumentarischen Berufsverbänden entwickelt worden ist und eine eindeutige Nähe zu bibliothekarischen Katalogisierungsregeln aufweist Warum sich die Norm nicht durchgesetzt hat, darüber kann nur spekuliert werden. Möglich ist, dass der Text mit einem Umfang von 18 Seiten - allein für Teil 2 der Norm! - zu umfangreich ist, als dass sich jemand, der sich für Formalia des wissenschaftlichen Arbeitens nur am Rande interessiert, wirklich damit beschäftigen würde. Möglich ist ferner, dass das Zitierformat zu nah an bibliothekarische Regeln angelehnt ist und einige Gepflogenheiten wissenschaftlicher Literaturverzeichnisse, die sich bei aller Uneinheitlichkeit doch durchgesetzt haben - nicht ausreichend berücksichtigt: Die Tendenz geht zu einer recht knappen Zitierweise, außerdem steht das Erscheinungsjahr inzwischen fast immer direkt hinter der Verfasserangabe und nicht irgendwo am Ende einer langen Titelaufnahme. Wie dem auch sei: Es ist bedauerlich, dass die Regelungen der Norm so wenig bekannt sind und damit kaum als Hilfestellung bei der oft auch beklagten Unsicherheit, wie korrekt zu zitieren sei, angesehen werden können. Vielleicht wäre hier eine viel intensivere Öffentlichkeitsarbeit angesagt, der Abdruck in einem neuen DIN-Taschenbuch ist sicherlich ein Schritt in die richtige Richtung. Eine andere Maßnahme wäre eine Aktualisierung der Norm; immerhin ist sie seit Januar 1984 unverändert geblieben. Über Namensverfremdungen wie Ernst T. A. Hoffmann ist die Bibliothekswelt inzwischen hinaus; ob gerade solch eine Regelung der Abkürzung von Vornamen und die Aufführung dieses Beispiels die Akzeptanz der Norm fördern, erscheint mehr als fraglich. Es ist im Rahmen einer Rezension nicht möglich, auf jede einzelne abgedruckte Norm inhaltlich einzugehen, daher nur noch einige Bemerkungen zu besonderen Auffälligkeiten. Das Taschenbuch gibt die internationale Norm ISO 690-2 (in englischer Sprache) wieder: "Information and documentation - Bibliographic references - Part 2: Electronic documents or parts thereof". Bei solch einem Thema, bei dem noch allgemeine Unsicherheit herrscht, ist es sehr hilfreich, mit der Norm eine Richtschnur an die Hand zu bekommen, auch wenn der Text selbst realistischerweise nicht den Anspruch erhebt, das Problem abschließend zu behandeln. Auf ein ganz besonders schwieriges Gebiet haben sich die Normungsausschüsse vorgewagt, als sie die internationale Norm ISO 11620 "Leistungsindikatoren für Bibliotheken" entwickelt haben, die ins Deutsche übersetzt und unverändert als DIN-Norm übernommen worden ist. Der Zweck der Norm wird eher zurückhaltend formuliert: Es geht darum, "den Gebrauch von Leistungsindikatoren in Bibliotheken zu unterstützen und Kenntnisse über die Durchführung von Leistungsmessung zu verbreiten" (S. 171). Dabei wird ausdrücklich zugestanden, dass es auch Leistungsindikatoren geben kann, die in dieser Norm nicht aufgeführt sind. Eine sehr realistische und damit sympathische Sicht für eine Fragestellung, die eins der jüngsten Probleme der bibliothekarischen Berufspraxis berührt und vermutlich nie erschöpfend ausdiskutiert werden kann! Im Vergleich dazu wirken Abkürzungs-, Transliterations- und Ordnungsregeln geradezu trivial. Aber alle, die im Bibliotheks- und Dokumentationsbereich tätig sind, wissen, dass es ohne Sorgfalt im Kleinen nicht geht und exakte Regelungen die tägliche Arbeit eher erleichtern.
