    Abstract
    Mit elektronischem Publizieren werden folgende Eigenschaften verbunden: »schnell, kostengünstig, weltweit«. Aber ist das aus Nutzersicht bzw. aus der Perspektive der Autoren ausreichend, um eine Online-Veröffentlichung dauerhaft zu nutzen und zuverlässig zu zitieren? Ein Mechanismus, mit dem netzbasierte Publikationen eindeutig gekennzeichnet werden und jederzeit auffindbar sind, wird durch flüchtige Uniform Resource Locator (URLs) nicht bereitgestellt. Eine Lösung bieten Persistent Identifiers (Pls), wie z. B. Uniform Resource Names (URN)". Damit die Anwendung eines persistenten Adressierungsschemas wie den URNs langfristig gewährleistet werden kann, muss eine Infrastruktur mit einer institutionellen Unterstützung geschaffen werden. Ein wesentlicher Aspekt in diesem Kontext ist die Langzeitarchivierung der digitalen Objekte. Die Darstellung und Erläuterung der Schnittstellen zwischen Langzeitarchivierung und Pls sowie der damit verbundenen Aktivitäten und Ergebnisse des EPICUR-Projektes war Gegenstand des Vortrages von Kathrin Schroeder auf dem diesjährigen z. Bibliothekskongress in Leipzig im Rahmen des Workshops »Technische Aspekte der Langzeitarchivierung«". Es besteht ein enger Zusammenhang zwischen den Bereichen Pls (standortunabhängige, eindeutige Bezeichner für digitale Objekte) und Langzeitarchivierung (Maßnahmen, die dazu dienen, digitale Objekte für die Nachwelt dauerhaft zu erhalten): Pls werden als stabiler Zugriffsmechanismus für digitale Objekte verwendet, die in einem Depotsystem archiviert werden. Ein Depotsystem ist ein »( ...) Archiv für digitale Objekte, in dem Menschen und Systeme als 'Organisation' mit der Aufgabenstellung zusammenwirken, Informationen zu erhalten und einer definierten Nutzerschaft verfügbar zu machen.« Dazu gehören im erweiterten Sinne auch eine Infrastruktur vor der Eingangsschnittstelle des Depotsystems, die zum Transfer digitaler Objekte von den Produzenten in das Archiv dient, und die Infrastruktur der Endnutzer-Umgebungen hinter der Auslieferungsschnittstelle des Depotsystems, in denen die digitalen Objekte benutzt werden sollen. In diesem Umfeld werden Pls in folgenden Bereichen angewendet: - Metadaten, - Datenaustauschformate, - Automatisierte Lieferungen von Objekten in ein Archivsystem, - Depotsystem und - Nutzung von Pls als stabiler Zugriffsmechanismus auf ein Objekt als wichtigster Aspekt für den Endnutzer (Wissenschaftler und Autoren). Im Folgenden werden zu den einzelnen Bereichen die Ergebnisse des EPICUR-Projektes und die Aktivitäten Der Deutschen Bibliothek diskutiert.

    Abstract
    Describes an approach to retrieving environmental sciences information on the Internet using metadatabases. an inf-sheet is created in a flat file system for each resource. The contents of theses sheets are structured by different fields which hold different types of information. 2 classes of information can be distinguished: information describing the content of a resource, which is searchable, and information which links to the resources (URL). A rough automated selection is performed, humans analyze the pre selected resources, and a final selection and indexing is carried out. An algorithm which controle the validity of the meta information is implemented. Describes 2 implemented examples, the Register of Ecological Models and the Metadatabase of Internet Resources

    Abstract
    Subject oriented information sources on the Internet remain relativley unstructured despite attempts at indexing them and despite the use of search engines to index sources in a collective database and to retrieve relevant information sources. Describes the rationale for developing a means to capture and structure Internet resources for scientific research use in a clearinghouse, and methods for retrieval, information filtering, and structuring subject orientated information sources from the Internet for specific user groups. Discusses the issues of design, maintenance, implementation of metadata, and obtaining use feedback. Cooperation among several institutions involved in the German national subject special collections (SSG) library support programme of the DFG have led to recommendations to expand this programme to include coordination of collective Internet subject information sites. In addition to the compilation of subject oriented information sites on the Internet by library and information staff, connection to other value added services serve to make processes of information searching, retrieval, acquisition, and evaluation more effective for researchers

    Abstract
    This paper deals with the problem of modeling Web information resources using expert knowledge and personalized user information for improved Web searching capabilities. We propose a "Web information space" model, which is composed of Web-based information resources (HTML/XML [Hypertext Markup Language/Extensible Markup Language] documents an the Web), expert advice repositories (domain-expert-specified metadata for information resources), and personalized information about users (captured as user profiles that indicate users' preferences about experts as well as users' knowledge about topics). Expert advice, the heart of the Web information space model, is specified using topics and relationships among topics (called metalinks), along the lines of the recently proposed topic maps. Topics and metalinks constitute metadata that describe the contents of the underlying HTML/XML Web resources. The metadata specification process is semiautomated, and it exploits XML DTDs (Document Type Definition) to allow domain-expert guided mapping of DTD elements to topics and metalinks. The expert advice is stored in an object-relational database management system (DBMS). To demonstrate the practicality and usability of the proposed Web information space model, we created a prototype expert advice repository of more than one million topics/metalinks for DBLP (Database and Logic Programming) Bibliography data set. We also present a query interface that provides sophisticated querying fa cilities for DBLP Bibliography resources using the expert advice repository.

    Abstract
    A 1 day seminar was held in Aug 1997, in Synney, Australia, sponsored by the Information science Section of the australia Library and Information Association, on metadata. It focused on building a conceptual framework for metadata. The National Library is developing PANDORA (Preserving and Accessing Networked documentary Resources of Australia) an electronic archive designed to provide long term access to significant Australian online publications. An architecture for access to government information has been developed. The Distributed System Technology Centre's Resource Discivery Project Unit has developed an information presentation tool called HyperIndex and a meta-data searcher called HotOIL

    Abstract
    Information professions identified the need for a set of standard metadata almost as soon as the WWW became a reality. Several initiatives have already identified the types of bibliographic information that would be necessary to describe and locate an electronic publication. The descriptors identified in the OCLC/NCSA Dublin Core are combined with those assembled by the Coalition of Networked Information and the Internet Engineering Task force to produce a list of electronic citation elements. Advocates embedding these citation elements within electrinic documents through the use of HTML<META>tags and other markup techniques. There is also a call to cataloguing librarians to contribute their expertise in information resources management to document being prepared for the WWW in order to influence the quality of electronic publication from the insides

    Abstract
    Discusses how information will be found in digital libraries of the future. Suggests that a metadata approach to cataloguing will prevail, whereby the content of the data will be analysed at source, rather than on receipt by an intermediary, altering the role of the cataloguer, who will be required to evaluate as well as classify and index. Web site administrators may have to provide site metadata for use by global indexers; provides some examples of projects aimed at developing standards and assisting information providers in creating descriptive metadata

    Abstract
    We discuss the issues of resolving the information-retrieval problem in large digital collections through the identification and use of document genres. Explicit identification of genre seems particularly important for such collections because any search usually retrieves documents with a diversity of genres that are undifferentiated by obvious clues as to their identity. Also, because most genres are characterized by both form and purpose, identifying the genre of a document provides information as to the document's purpose and its fit to the user's situation, which can be otherwise difficult to assess. We begin by outlining the possible role of genre identification in the information-retrieval process. Our assumption is that genre identification would enhance searching, first because we know that topic alone is not enough to define an information problem and, second, because search results containing genre information would be more easily understandable. Next, we discuss how information professionals have traditionally tackled the issues of representing genre in settings where topical representation is the norm. Finally, we address the issues of studying the efficacy of identifying genre in large digital collections. Because genre is often an implicit notion, studying it in a systematic way presents many problems. We outline a research protocol that would provide guidance for identifying Web document genres, for observing how genre is used in searching and evaluating search results, and finally for representing and visualizing genres.

    Abstract
    The main objective of the proposed high-level 'Visual Repository Definition Language' is to anbale advanced Web presentation of large amounts of exisitng heterogeneous information. Statements of the language serve to describe the desired structure of information repositories, which are composed of metadata entities encapsulating the original data. Such approach helps to to avoid the usual relocation and restructuring of data that occurs when providing Web access to it. The language has been designed to be useful even for inexperienced programmers. Its applicability is demonstrated by a real example, creating a repository of judicial opinions from publicly available raw data

    Abstract
    Comments on the value of abstracts or summary notes to information available online via the Internet and WWW and concludes that automated abstracting techniques would be highly useful if routinely applied to cataloguing or metadata for Internet documents and documents in other databases. Information seekers need external summary information to assess content and value of retrieved documents. Examines traditional models for writers, in library audiovisual cataloguing, periodical databases and archival work, along with innovative new model databases featuring robust cataloguing summaries. Notes recent developments in automated techniques, computational research, and machine summarization of digital images. Recommendations are made for future designers of cataloguing and metadata standards

    Abstract
    Describes the structure of metadata formats with particular reference to the taxonomy of data formats set out by the BIBLINK report of the UK Office for Library and Information Networking and based on their underlying complexity. Referes to 3 main types of metadata: Dublin Core; MARC and Federal Geographic Data Committee (FGDC). Provides practical examples of the actual codings used, illustrated with reference to the Dublin Core, Marc and FGDC elements in selected Web sites. Ends with a glossary and a list of Web sites containing background information on metadata, such as the IAMSLIC metadata homepage

    Abstract
    The relationship between library catalogues and electronic resources differs from that between catalogues and physical materials, particularly with regard to cataloguing rules, which were originally designed to help users of card catalogues to find physical works on library shelves. However, these rules apply awkwardly to electronic resources because functionally different electronic works raise special cataloguinf issues. Discusses the problems of describing remote electronic resources in online catalogues with particular reference to the InterCat project: a nationwide experiment to create a database of Internet resources in MARC format, containing description, location and access information (including PURLs = Persitent URLs)). Concludes that descriptive information helps the user identify the works needed, but that it is practical to provide only minimal desriptive information for remote electronic resources in the catalogue record. To a limited extent, the access lost from reduced description can be replaced with new cataloguing techniques designed to stabilize the catalogue record

    Abstract
    Reports results of a study of 4 WWW search engines: AltaVista; Lycos; Excite and WebCrawler to collect data on Web objects on polymer chemistry. 1.037 Web objects were examined for data in 4 categories: document information; use of meta fields; use of images and use of chemical names. Issues raised included: whether to provide metadata elements for parts of entities or whole entities only, the use of metasyntax, problems in representation of special types of objects, and whether links should be considered when encoding metadata. Use of metafields was not widespread in the sample and knowledge of metafields in HTML varied greatly among Web object creators. The study formed part of a metadata project funded by the OCLC Library and Information Science Research Grant Program
