The aim of this initiative is to provide the users of online library catalogues and information gateways of cooperating libraries with a prototype for multilingual subject searching in online environment. Library collections of these libraries are large and without any doubt very valuable for researchers throughout Europe. What is needed is a standardized, authorized indexing and retrieval tool which would bring together all their catalogues and databases and enable multilingual subject searching. At the beginning of the project, a number of factors affecting subject indexing in current environment and cross-searching for subjects have been identified. These factors include - standardization of subject retrieval process and indexing and classification tools - subject retrieval methods - possibility of interoperability among different indexing and classification schemes - multilingualism issue - possibility to increase precision and recall trough Z39.50 protocol and its profiles and to apply authority control in subject retrieval process - need for cooperation

Abstract

This article focuses on the use of the German language subject headings authority file SWD (Schlagwortnormdatei) in Austria and outlines how Austrian academic libraries' employment of the SWD developed in active cooperation with their SWD partners. The Austrian subject indexing practice turned to the SWD terminology based on the newly published German subject indexing rules RSWK (Regeln für den Schlagwortkatalog) in the late 1980s. An electronic workflow was developed. Soon it became necessary to provide a data pool for new terms originally created by Austrian member libraries and to connect these data with the SWD source data (ÖSWD, 1991). Internal cooperation structures developed when local SWD editorial departments began to exist. As of 1994 a central editor was nominated to serve as direct link between active Austrian SWD users and SWD partners and the German National Library (DNB). Unfortunately the first active SWD period was followed by a long term vacancy due to the first central editor's early retirement. Nearly all functional and information structures stopped functioning while local data increased on a daily basis... In 2004 a new central ÖSWD editor was nominated, whose first task it was to rebuild structures, to motivate local editors as well as terminology experts in Austria, to create a communication network for exchanging information and to cooperate efficiently with the DNB and Austria's SWD partners. The great number of old data and term duplicates and the special role of personal names as subject authority data in the Austrian library system meant that newly created and older or reused terms had to be marked in a special way to allow for better segmentation and revision. Now, in 2008, the future of Austrian SWD use looks bright. Problems will continue to be overcome as the forthcoming new online editing process for authority files provides new challenges.

Abstract

Die Suche nach wirtschaftswissenschaftlicher Literatur im Internet führt heute zu unterschiedlich erschlossenen Informationsbeständen. Die Antwort auf diese Heterogenität sollte das Angebot einer integrierten sachlichen Suche über verteilte Datenbanken sein. Crosskonkordanzen unterstützen diese Entwicklung, indem sie Suchfragen in die Terminologie verschiedener Thesauri übersetzen. Nutzern von Bibliotheken und Fachinformationszentren wird das Navigieren erleichtert, sie ersparen sich Mehrfachrecherchen und können auf ihre vertraute Indexierungssprache zurückgreifen. Wirtschaftswissenschaftliche Literatur wird in Deutschland mit verschiedenen Thesauri indexiert. Einerseits bieten Hochschulbibliothekskataloge eine sachliche Suche mit den Schlagwörtern der Schlagwortnormdatei (SWD) an, andererseits sind wirtschaftswissenschaftliche Fachdatenbanken mit dem Standard Thesaurus Wirtschaft (STW) erschlossen. Hier setzt das Angebot der Crosskonkordanz Wirtschaft an - ein Retrieval-Instrument für sachlich heterogen erschlossene Datenbestände." Concordans bedeutet »übereinstimmend«, »zusammenhängend«, »verknüpft«, wir verknüpfen also die Deskriptoren (Sachbegriffe) der SWD im Bereich Wirtschaft mit den Deskriptoren des STW. Die SWD, getragen und entwickelt von Der Deutschen Bibliothek und den Bibliotheksverbünden des deutschen Sprachraums, ist das Instrument zur Indexierung der gesamten deutschsprachigen wirtschaftswissenschaftlichen Literatur. Auch unselbstständige Literatur wird beispielsweise von der Universitätsbibliothek Köln als Sondersammelgebiet Betriebswirtschaftslehre mithilfe der SWD erschlossen. Trotz ihres eigentlichen Charakters als Allgemeinthesaurus ist sie im Bereich Wirtschaft besonders differenziert entwickelt und enthält etwa 12.500 Deskriptoren. Der STW ist der bedeutendste Fachthesaurus für Wirtschaftswissenschaften in der Bundesrepublik Deutschland. Getragen vom Hamburgischen WeIt-Wirtschafts-Archiv (HWWA), der Deutschen Zentralbibliothek für Wirtschaftswissenschaften in Kiel (ZBW) und der Gesellschaft für Betriebswirtschaftliche Information München findet er Anwendung in verschiedenen Fachdatenbanken. Der STW enthält rund 5.000 Deskriptoren

Abstract

InterParty is a project that aims to develop a mechanism that will enable the interoperation of identifiers for "parties" or persons (authors, publishers, etc. - persons and corporate bodies in library authority files) across multiple domains. Partners represent the book industry, rights management, libraries, and identifier and technology communities, united by their perception of a common benefit from interoperation in terms of access to "common metadata" held by other members to improve the quality of their own data. The InterParty solution proposes a distributed network of members who provide access to "common metadata," defined as information in the public domain, sufficient to identify and distinguish the "public identity" of a person. At a minimum the InterParty network would provide access to multiple domains of data about persons, including multiple library authority files, author licensing data files, etc. It will also add value by providing a facility for linking records between different data files by means of a "link record." Link records will assert that an identity recorded in one database is the same as another identity recorded in another database. Linked data will be mutually enriching and therefore more reliable and supportive of accurate disambiguation of persons within and between databases. InterParty has potential to develop a common system that supports both the emerging needs of e-commerce and the traditional requirements of library authority control.

Abstract

During the retrospective conversion of its printed and card catalogues, the Bibliothèque nationale de France was confronted with the existence of old bibliographic records without corporate body headings, because this concept was unknown when the books were catalogued. The Library launched two programs aimed at creating authority records for specific fields important for the access to the national bibliographic heritage, respectively named COFAR -- for the official corporate bodies, mainly national and preceding the French Revolution - and CORELI - for the religious corporate bodies (parishes, dioceses, confraternities, orders and congregations, etc.). The 2550 records created by the COFAR and CORELI programs have been included in the authority file of BNOPALE PLUS; so they are visible either via the online catalogue or separately with other authority records. They give librarians an extra tool for identifying entities. They represent also a valuable source of information accessible to anyone who takes an interest in the history of French government institutions or religious entities.

Abstract

Die Deutsche Bibliothek, the Library of Congress, and OCLC Online Computer Library Center are jointly developing a virtual international authority file (VIAF) for personal names which links authority records from the world's national bibliographic agencies and will be made freely available on the Web. The goals of the project are to prove the viability of automatically linking authority records from different national authority files and to demonstrate its benefits. The authority and bibliographic files from the Library of Congress and Die Deutsche Bibliothek were used to create the initial VIAF which contains over six million names with over a half million links. A key aspect of the project was the development of automated name matching algorithms which use information from both authority records and the corresponding bibliographic records. The practicality of algorithmically linking the personal names between national authority files was demonstrated; seventy percent of the authority records for personal names common to both files were automatically linked with an error rate of less than one percent. The long-term goal of the VIAF project is to combine the authoritative names from many national libraries and other significant sources into a shared global authority service.

Abstract

This article presents an overview of the LEAF project (Linking and Exploring Authority Files)1, which has set out to provide a framework for international, collaborative work in the sector of authority data with respect to authority control. Elaborating the virtues of authority control in today's Web environment is an almost futile exercise, since so much has been said and written about it in the last few years.2 The World Wide Web is generally understood to be poorly structured-both with regard to content and to locating required information. Highly structured databases might be viewed as small islands of precision within this chaotic environment. Though the Web in general or any particular structured database would greatly benefit from increased authority control, it should be noted that our following considerations only refer to authority control with regard to databases of "memory institutions" (i.e., libraries, archives, and museums). Moreover, when talking about authority records, we exclusively refer to personal name authority records that describe a specific person. Although different types of authority records could indeed be used in similar ways to the ones presented in this article, discussing those different types is outside the scope of both the LEAF project and this article. Personal name authority records-as are all other "authorities"-are maintained as separate records and linked to various kinds of descriptive records. Name authority records are usually either kept in independent databases or in separate tables in the database containing the descriptive records. This practice points at a crucial benefit: by linking any number of descriptive records to an authorized name record, the records related to this entity are collocated in the database. Variant forms of the authorized name are referenced in the authority records and thus ensure the consistency of the database while enabling search and retrieval operations that produce accurate results. On one hand, authority control may be viewed as a positive prerequisite of a consistent catalogue; on the other, the creation of new authority records is a very time consuming and expensive undertaking. As a consequence, various models of providing access to existing authority records have emerged: the Library of Congress and the French National Library (Bibliothèque nationale de France), for example, make their authority records available to all via a web-based search service.3 In Germany, the Personal Name Authority File (PND, Personennamendatei4) maintained by the German National Library (Die Deutsche Bibliothek, Frankfurt/Main) offers a different approach to shared access: within a closed network, participating institutions have online access to their pooled data. The number of recent projects and initiatives that have addressed the issue of authority control in one way or another is considerable.5 Two important current initiatives should be mentioned here: The Name Authority Cooperative (NACO) and Virtual International Authority File (VIAF).
NACO was established in 1976 and is hosted by the Library of Congress. At the beginning of 2003, nearly 400 institutions were involved in this undertaking, including 43 institutions from outside the United States.6 Despite the enormous success of NACO and the impressive annual growth of the initiative, there are requirements for participation that form an obstacle for many institutions: they have to follow the Anglo-American Cataloguing Rules (AACR2) and employ the MARC217 data format. Participating institutions also have to belong to either OCLC (Online Computer Library Center) or RLG (Research Libraries Group) in order to be able to contribute records, and they have to provide a specified minimum number of authority records per year. A recent proof of concept project of the Library of Congress, OCLC and the German National Library-Virtual International Authority File (VIAF)8-will, in its first phase, test automatic linking of the records of the Library of Congress Name Authority File (LCNAF) and the German Personal Name Authority File by using matching algorithms and software developed by OCLC. The results are expected to form the basis of a "Virtual International Authority File". The project will then test the maintenance of the virtual authority file by employing the Open Archives Initiative Protocol for Metadata Harvesting (OAI-PMH)9 to harvest the metadata for new, updated, and deleted records. When using the "Virtual International Authority File" a cataloguer will be able to check the system to see whether the authority record he wants to establish already exists. The final phase of the project will test possibilities for displaying records in the preferred language and script of the end user. Currently, there are still some clear limitations associated with the ways in which authority records are used by memory institutions. One of the main problems has to do with limited access: generally only large institutions or those that are part of a library network have unlimited online access to permanently updated authority records. Smaller institutions outside these networks usually have to fall back on less efficient ways of obtaining authority data, or have no access at all. Cross-domain sharing of authority data between libraries, archives, museums and other memory institutions simply does not happen at present. Public users are, by and large, not even aware that such things as name authority records exist and are excluded from access to these information resources.

"Standardisierung - Auch 2007 ist die Arbeitsstelle für Standardisierung (AfS) auf dem Weg zur Internationalisierung der deutschen Regelwerke, Formate und Normdateien entscheidende Schritte vorangekommen. Im Mittelpunkt der Vorbereitungen für den Format-umstieg standen eine Konkordanz von MAB2 nach MARC 21 und die Festlegung neuer Felder, die für den Umstieg auf nationaler Ebene notwendig sind. Neben einer Vielzahl anderer Aktivitäten hat die DNB zwei Veranstaltungen zum Format-umstieg durchgeführt. In Zusammenarbeit mit den Expertengruppen des Standardisierungsausschusses wurden drei Stellungnahmen zu Entwürfen des Regelwerkes »Resource Description and Access (RDA)« erarbeitet; es fand eine Beteiligung an der internationalen Diskussion zu wichtigen Grundlagen statt. Der Erfüllung des Wunsches nach Einführung der Onlinekommunikation mit Normdateien ist die DNB im vergangenen Jahr deutlich nähergekommen: Änderungen an Normdaten sollen gleichzeitig in die zentral bei der DNB gehaltenen Dateien und in der Verbunddatenbank vollzogen werden. Seit Anfang September ist die erste Stufe der Onlinekommunikation im produktiven Einsatz: Die PND-Redaktionen in den Aleph-Verbünden arbeiten online zusammen. Das neue Verfahren wird sich auf alle bei der DNB geführten Normdaten erstrecken und in einem gestuften Verfahren eingeführt werden. Die DNB war in zahlreichen Standardisierungsgremien zur Weiterentwicklung von Metadatenstandards wie z.B. Dublin Core und ONIX (Online Information eXchange) sowie bei den Entwicklungsarbeiten für The European Library beteiligt. Die Projektarbeiten im Projekt KIM - Kompetenzzentrum Interoperable Metadaten wurden maßgeblich unterstützt. Im Rahmen der Arbeiten zum Gesetz über die Deutsche Nationalbibliothek wurde ein Metadatenkernset für die Übermittlung von Metadaten an die DNB entwickelt und in einer ersten Stufe mit einem ONIX-Mapping versehen. Innerhalb des Projektes »Virtual International Authority File - VIAF« entwickelten die Library of Congress (LoC), die DNB und OCLC - zunächst für Personennamen - gemeinsam eine virtuelle, internationale Normdatei, in der die Normdatensätze der nationalen Normdateien im Web frei zugänglich miteinander verbunden werden sollen. Die bisherigen Projektergebnisse haben die Machbarkeit einer internationalen Normdatei eindrucksvoll unter Beweis gestellt. Darum haben die Projektpartner in einem neuen Abkommen, das auch die Bibliothèque Nationale de France einschließt, im Oktober 2007 ihr Engagement für den VIAF nochmals bekräftigt und damit eine Konsolidierungs- und Erweiterungsphase eingeleitet."
"DDC-vascoda - Das Projekt DDC-vascoda wurde 2007 abgeschlossen. Für den Sucheinstieg bei vascoda wurde bislang nur eine Freitextsuche über alle Felder oder eine Expertensuche, bei der die Freitextsuche mit den formalen Kriterien Autor, Titel und (Erscheinungs-)Jahr kombiniert werden kann, angeboten. Die Suche konnte zwar auf einzelne Fächer oder Fachzugänge beschränkt werden, ein sachlicher Zugang zu der Information fehlt jedoch. Vascoda verwendete die Dewey Decimal Classification (DDC) als einheitliches Klassifikationsinstrument. Ziel des Projektes DDC-vascoda war es, über diese Klassifikation einen komfortablen und einheitlichen sachlichen Zugang als Einstieg in das Gesamtangebot einzurichten. Weiterhin wurde ein HTML-Dienst entwickelt, der es Fachportalen und anderen Datenanbietern ermöglicht, ohne großen Programmieraufwand ein DDC-Browsing über die eigenen Daten bereitzustellen."
