    Abstract
    Z39.50 is an information retrieval protocol. It has generated much interest but is so far little deployed in UK systems and services. Gives a functional overview of the protocol itself and the standards background, describes some European initiatives which make use of it, and outlines various issues to do with its future use and acceptance. Z39.50 is a crucial building block of future distributed information systems but it needs to be considered alongside other protocols and services to provide useful applications

    Abstract
    Purpose - Biodiversity resources are inevitably digital and stored in a wide variety of formats by researchers or stakeholders. In Malaysia, although digitizing biodiversity data has long been stressed, the interoperability of the biodiversity data is still an issue that requires attention. This is because, when data are shared, the question of copyright occurs, creating a setback among researchers wanting to promote or share data through online presentations. To solve this, the aim is to present an approach to integrate data through wrapping of datasets stored in relational databases located on networked platforms. Design/methodology/approach - The approach uses tools such as XML, PHP, ASP and HTML to integrate distributed databases in heterogeneous formats. Five current database integration systems were reviewed and all of them have common attributes such as query-oriented, using a mediator-based approach and integrating a structured data model. These common attributes were also adopted in the proposed solution. Distributed Generic Information Retrieval (DiGIR) was used as a model in designing the proposed solution. Findings - A new database integration system was developed, which is user-friendly and simple with common attributes found in current integration systems.

    Abstract
    Federated search and distributed information retrieval systems provide a single user interface for searching multiple full-text search engines. They have been an active area of research for more than a decade, but in spite of their success as a research topic, they are still rare in operational environments. This article discusses a prototype federated search system developed for the U.S. government's FedStats Web portal, and the issues addressed in adapting research solutions to this operational environment. A series of experiments explore how well prior research results, parameter settings, and heuristics apply in the FedStats environment. The article concludes with a set of lessons learned from this technology transfer effort, including observations about search engine quality in the real world.

    Abstract
    The aims of CATRIONA were: (1) to investigate the requirements for developing procedures and applications for cataloguing and retrieval of networked resources, and (2) to explore the feasibility of a collaborative project to develop such applications and procedures and integrate them with existing library systems. The project established that a distributed catalogue of networked resources integrated with standard Z39.50 library system OPAC interfaces with information on hard-copy resources is already a practical proposition at a basic level. At least one Z39.50 OPAC client can search remote Z39.50 OPACs, retrieve USMARC records with URLs in 856$u, load a viewer like Netscape, and use it to retrieve and display the remotely held electronic resource on the local workstation. A follow-up project on related issues is being finalised.

    Abstract
    This article describes two approaches for searching heterogeneous resources, which are explained as they are used in two corresponding existing systems-RIRS (Resource Integration Retrieval System) and HRUSP (Heterogeneous Resource Union Search Platform). On analyzing the existing systems, a possible framework-the MUSP (Multimetadata-Based Union Search Platform) is presented. Libraries now face a dilemma. On one hand, libraries subscribe to many types of database retrieval systems that are produced by various providers. The libraries build their data and information systems independently. This results in highly heterogeneous and distributed systems at the technical level (e.g., different operating systems and user interfaces) and at the conceptual level (e.g., the same objects are named using different terms). On the other hand, end users want to access all these heterogeneous data via a union interface, without having to know the structure of each information system or the different retrieval methods used by the systems. Libraries must achieve a harmony between information providers and users. In order to bridge the gap between the service providers and the users, it would seem that all source databases would need to be rebuilt according to a uniform data structure and query language, but this seems impossible. Fortunately, however, libraries and information and technology providers are now making an effort to find a middle course that meets the requirements of both data providers and users. They are doing this through resource integration.

    Abstract
    In this position paper we propose a document-centric middleware component called Living Documents to support context-aware information retrieval in distributed communities. A Living Document acts as a micro server for a document which contains computational services, a semi-structured knowledge repository to uniformly store and access context-related information, and finally the document's digital content. Our initial prototype of Living Documents is based an the concept of mobile agents and implemented in Java and XML.

    Abstract
    Die seit ca. 1996 rasche Entwicklung des Internet bzw. des World Wide Web (WWW) hat die Praxis der Veröffentlichung, Verbreitung und Nutzung wissenschaftlicher Informationen grundlegend verändert. Um diese Informationen suchbar und retrievalfähig zu gestalten, ist in den letzten Jahren international viel diskutiert worden. Ein vielversprechender Ansatz, diesen neuen Herausforderungen zu begegnen, liegt in der Entwicklung von Metadatenprofilen. Da durch das Internet verschiedene Datenbestände, die von unterschiedlichen Bereichen wie Museen, Bibliotheken, Archiven etc. vorgehalten werden, unter einer Oberfläche durchsucht werden können, können Metadaten auch in diesem Bereich dazu beitragen, ein einheitliches Konzept zur Beschreibung und zum Retrieval von Online-Ressourcen zu entwickeln. Um die verteilt liegenden Dokumente unter einer Oberfläche für eine qualitativ hochwertige Recherche ("Cross-Search`) anbieten zu können, ist die Verständigung auf ein Core-Set an Metadaten und daran anschließend verschiedene Mappingprozesse ("Cross-walk`) von den lokalen Metadatenformaten zu dem Format des Core-Set an Metadaten notwendig. Ziel des Artikels' ist es, die einzelnen Schritte, die für die Entwicklung eines Metadatenprofils für die gemeinsame Suche über verteilte Metadatensammlungen notwendig sind, aufzuzeigen.

    Abstract
    User demands to have access to complete and actual information about research may require integration of data from different CRISs. CRISs are rarely homogenous systems and problems of CRISs integration must be addressed from technological point of view. Implementation of CRIS providing access to heterogeneous data distributed among a number of CRISs is described. A few technologies - distributed databases, web services, semantic web are used for distributed CRIS to address different user requirements. Distributed databases serve to implement very efficient integration of homogenous systems, web services - to provide open access to research information, semantic web - to solve problems of integration semantically and structurally heterogeneous data sources and provide intelligent data retrieval interfaces. The problems of data completeness in distributed systems are addressed and CRIS-adequate solution for data completeness is suggested.

    Abstract
    Nowadays, users of information services are faced with highly decentralised, heterogeneous document sources with different content analysis. Semantic heterogeneity occurs e.g. when resources using different systems for content description are searched using a simple query system. This report describes several approaches of handling semantic heterogeneity used in projects of the German Social Science Information Centre

    Abstract
    Das steigende Angebot an Datenbanken und weiteren Systeme im Bereich bibliografischer Informationen führt dazu, dass es für Benutzer sehr mühsam und mit einem enormen Zeitaufwand verbunden ist, in allen einzelnen Systemen zu recherchieren, da diese unterschiedliche Benutzeroberflächen und Recherchemöglichkeiten anbieten. Verteilte bibliografische Informationssysteme ermöglichen einen einheitlichen Einstiegspunkt zu heterogenen Systemen. Sie bündeln verschiedene Angebote. In diesem Text wird ein Überblick über diese verteilten Informationssysteme gegeben. Es wird dargestellt, wie eine Suche in einem solchen System abläuft, welche weiteren Funktionen angeboten werden können. Darüber hinaus wird betrachtet, wie verteilte Informationssysteme aufgebaut und vernetzt sind. Die Darstellungen werden verdeutlicht durch praktische Beispiele aus dem Bibliotheks- und Informationswesen. Insbesondere wird auf den KVK, ZACK, die KOBVSuchmaschine, die Digitale Bibliothek NRW, das DIMDI, vascoda und Renardus eingegangen.

    Abstract
    The State Library of Iowa, USA, received a Higher Education Act title II grant from the US Dept. of Education in 1994 to create a demonstration project of new library information technologies. Describes 2 interlinked components of the project: Web-based union catalogue development and statewide deployment of the ANSI/NISO Z39.50 standard for database search and retrieval. Z39.50 was chosen because of its ability to searching multiple remote databases in a single session and its common interface across a variety of implementations. Use of a distributed Z39.50 search makes the need for maintaining large union catalogues unnecessary

    Abstract
    The objective of the European Library (TEL) project [TEL] was to set up a co-operative framework and specify a system for integrated access to the major collections of the European national libraries. This has been achieved by successfully applying a new approach for search and retrieval via URLs (SRU) [ZiNG] combined with a new metadata paradigm. One aim of the TEL approach is to have a low barrier of entry into TEL, and this has driven our choice for the technical solution described here. The solution comprises portal and client functionality running completely in the browser, resulting in a low implementation barrier and maximum scalability, as well as giving users control over the search interface and what collections to search. In this article we will describe, step by step, the development of both the search and retrieval architecture and the metadata infrastructure in the European Library project. We will show that SRU is a good alternative to the Z39.50 protocol and can be implemented without losing investments in current Z39.50 implementations. The metadata model being used by TEL is a Dublin Core Application Profile, and we have taken into account that functional requirements will change over time and therefore the metadata model will need to be able to evolve in a controlled way. We make this possible by means of a central metadata registry containing all characteristics of the metadata in TEL. Finally, we provide two scenarios to show how the TEL concept can be developed and extended, with applications capable of increasing their functionality by "learning" new metadata or protocol options.

    Abstract
    The success of the World Wide Web Shows that we can access, search, and retrieve information from globally distributed databases. lf a database, such as a library catalog, has some sort of Web-based front end, we can type its URL into a Web browser and use its HTML-based forms to search for items in that database. Depending an how well the query conforms to the database content, how the search engine interprets the query, and how the server formats the results into HTML, we might actually find something usable. While the first two issues depend an ourselves and the server, an the Web the latter falls to the mercy of HTML, which we all know as a great destroyer of information because it codes for display but not for content description. When looking at an HTML-formatted display, we must depend an our own interpretation to recognize such entities as author names, titles, and subject identifiers. The Web browser can do nothing but display the information. lf we want some other view of the result, such as sorting the records by date (provided it offers such an option to begin with), the server must do it. This makes poor use of the computing power we have at the desktop (or even laptop), which, unless it involves retrieving more records, could easily do the result Set manipulation that we currently send back to the server. Despite having personal computers wich immense computational power, as far as information retrieval goes, we still essentially use them as dumb terminals.

    Rez. in: KO 31(2004) no.2, S.117-118 (D. Campbell): "This excellent volume offers 22 papers delivered at an IFLA Satellite meeting in Dublin Ohio in 2001. The conference gathered together information and computer scientists to discuss an important and difficult question: in what specific ways can the accumulated skills, theories and traditions of librarianship be mobilized to face the challenges of providing subject access to information in present and future networked information environments? The papers which grapple with this question are organized in a surprisingly deft and coherent way. Many conferences and proceedings have unhappy sessions that contain a hodge-podge of papers that didn't quite fit any other categories. As befits a good classificationist, editor I.C. McIlwaine has kept this problem to a minimum. The papers are organized into eight sessions, which split into two broad categories. The first five sessions deal with subject domains, and the last three deal with subject access tools. The five sessions and thirteen papers that discuss access in different domains appear in order of in creasing intension. The first papers deal with access in multilingual environments, followed by papers an access across multiple vocabularies and across sectors, ending up with studies of domain-specific retrieval (primarily education). Some of the papers offer predictably strong work by scholars engaged in ongoing, long-term research. Gerard Riesthuis offers a clear analysis of the complexities of negotiating non-identical thesauri, particularly in cases where hierarchical structure varies across different languages. Hope Olson and Dennis Ward use Olson's familiar and welcome method of using provocative and unconventional theory to generate meliorative approaches to blas in general subject access schemes. Many papers, an the other hand, deal with specific ongoing projects: Renardus, The High Level Thesaurus Project, The Colorado Digitization Project and The Iter Bibliography for medieval and Renaissance material. Most of these papers display a similar structure: an explanation of the theory and purpose of the project, an account of problems encountered in the implementation, and a discussion of the results, both promising and disappointing, thus far. Of these papers, the account of the Multilanguage Access to Subjects Project in Europe (MACS) deserves special mention. In describing how the project is founded an the principle of the equality of languages, with each subject heading language maintained in its own database, and with no single language used as a pivot for the others, Elisabeth Freyre and Max Naudi offer a particularly vivid example of the way the ethics of librarianship translate into pragmatic contexts and concrete procedures. The three sessions and nine papers devoted to subject access tools split into two kinds: papers that discuss the use of theory and research to generate new tools for a networked environment, and those that discuss the transformation of traditional subject access tools in this environment. In the new tool development area, Mary Burke provides a promising example of the bidirectional approach that is so often necessary: in her case study of user-driven classification of photographs, she user personal construct theory to clarify the practice of classification, while at the same time using practice to test the theory. Carol Bean and Rebecca Green offer an intriguing combination of librarianship and computer science, importing frame representation technique from artificial intelligence to standardize syntagmatic relationships to enhance recall and precision.

    Abstract
    During the 1990s statewide cooperative use of networks in the USA has moved towards providing mainly access to bibliographic and full-text resources not held locally and usually provided by commercial vendors for use by libraries. Describes 3 academic library networks: the University System of Maryland's Library Information Management System serving the information needs of users throughout the state; Georgia's GALILEO (Georgia Library Learning On-Line) which provides a set of electronic resources and services for the 34 colleges and universities of the University System of Georgia; and TexShare in which all 52 libraries from the public educational institutions in Texas participate. Although the development of funding sources, the technical implementations and support, and the management organization differ from state to state, all three reflect an incremental shift towards the electronic library

    Abstract
    Das Projekt CARMEN startete als Sonderfördermaßnahme im Rahmen von Global lnfo im Oktober 1999 mit einer geplanten Laufzeit von 29 Monaten. Der Schwerpunkt des Projekts liegt in der Weiterentwicklung von Konzepten und Verfahren der Dokumenterschließung, die den Zugriff auf heterogene, dezentral verteilte Informationsbestände und deren Verwaltung nach gemeinsamen Prinzipien ermöglichen sollen. Dabei geht CARMEN gezielt einen anderen Weg als die meisten bisherigen Ansätze in diesem Bereich, die versuchen, Homogenität und Konsistenz in einer dezentralen Informationslandschaft technikorientiert herzustellen, indem Verfahren entwickelt werden, durch die physikalisch auf verschiedene Dokumentenräume gleichzeitig zugegriffen werden kann. Eine rein technische Parallelisierung von Zugriffsmöglichkeiten reicht jedoch nicht aus, denn das Hauptproblem der inhaltlichen, strukturellen und konzeptionellen Differenz der einzelnen Datenbestände wird damit nicht gelöst. Um diese Differenzen zu kompensieren, werden Problemlösungen und Weiterentwicklungen innerhalb des Projekts CARMEN in drei Bereichen erarbeitet: (1) Metadaten (Dokumentbeschreibung, Retrieval, Verwaltung, Archivierung) (2) Methoden des Umgangs mit der verbleibenden Heterogenität der Datenbestände (3) Retrieval für strukturierte Dokumente mit Metadaten und heterogenen Datentypen. Diese drei Aufgabenbereiche hängen eng zusammen. Durch die Entwicklungen im Bereich der Metadaten soll einerseits die verlorengegangene Konsistenz partiell wiederhergestellt und auf eine den neuen Medien gerechte Basis gestellt werden. Andererseits sollen durch Verfahren zur Heterogenitätsbehandlung Dokumente mit unterschiedlicher Datenrelevanz und Inhaltserschließung aufeinander bezogen und retrievalseitig durch ein Rechercheverfahren erganzt werden, das den unterschiedlichen Datentypen gerecht wird Innerhalb des Gesamtprojekts CARMEN werden diese Aspekte arbeitsteilig behandelt. Acht Arbeitspakete (APs) befassen sich in Abstimmung miteinander mit je verschiedenen Schwerpunkten. Um die Koordination der Arbeiten der verschiedenen APs untereinander zu unterstützen, trafen sich die ca. 40 Projektbearbeiter am 1. und 2. Februar 2001 zum "CARMEN middle OfTheRoad Workshop" in Bonn. Anlässlich dieses Workshops wurden die inhaltlichen und technischen Ergebnisse, die in der ersten Hälfte der Projektlaufzeit von den einzelnen APs erzielt worden sind, in insgesamt 17 Präsentationen vorgestellt
