- 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
- Examines international efforts to promote metadata as a common, interactive resource description tool for the Internet. These efforts centre on the Dublin Core Element Set, but include qualifiers such as those promoted by the Canberra Qualifiers. The LoC Network Development and MARC Standards Office maintains the Dublin Core / MARC / GILS (Government Information Location Standards) crosswalk which maps the common and correlative elements of each system. Describes current international initiatives and issues. Describes the Nordic metadata project which is aiming to create the basic elements of a metadata production and utilization system based on the Dublin Core Metadata Element Set. Describes the WWW consortium efforts in this area

- Abstract
- The Dublin Core is a 15 element set intended to facilitate discovery of electronic resources. Its characteristics are: simplicity, semantic interoperability, international consensus, flexibility, metadata modularity on the Web and a metadata architecture for the Web. The WWW Consortium is developing the Resource Description Framework to support different metadata needs. It will support 3 resource description models: embedded metadata, third party metadata, and view filter. Development continues into: refinement of elements, user education and application guides, metadata registries, tools and standardization. Includes a list of related Web sites and details of the core elements

- Abstract
- Discusses the goals and outcome of the OCLC/NCSA Metadata Workshop, held in Dublin, Ohio, 1-3 Mar 95, which resulted in the proposed 'Dublin Core' Metadata Elements. Describes an attempt to map the Dublin Core data elements to the USMARC format (with particular reference to USMARC field 856 for electronic locations), noting problems and outstanding questions. The USMARC format elements considered include: subject, title, author, other-agent, publisher, publication date, identifier, object-type, form, relation, language, source, coverage, and other issues

- Abstract
- We propose an extension of a mediator architecture. This extension is oriented to ontology-driven data integration. In our architecture ontologies are not managed by an extemal component or service, but are integrated in the mediation layer. This approach implies rethinking the mediator design, but at the same time provides advantages from a database perspective. Some of these advantages include the application of optimization and evaluation techniques that use and combine information from all abstraction levels (physical schema, logical schema and semantic information defined by ontology). 1. Introduction Although the Web is probably the richest information repository in human history, users cannot specify what they want from it. Two major problems that arise in current search engines (Heflin, 2001) are: a) polysemy, when the same word is used with different meanings; b) synonymy, when two different words have the same meaning. Polysemy causes irrelevant information retrieval. On the other hand, synonymy produces lost of useful documents. The lack of a capability to understand the context of the words and the relationships among required terms, explains many of the lost and false results produced by search engines. The Semantic Web will bring structure to the meaningful content of Web pages, giving semantic relationships among terms and possibly avoiding the previous problems. Various proposals have appeared for meta-data representation and communication standards, and other services and tools that may eventually merge into the global Semantic Web (Berners-lee, 2001). Hopefully, in the next few years we will see the universal adoption of open standards for representation and sharing of meta-information. In this environment, software agents roaming from page to page can readily carry out sophisticated tasks for users (Berners-Lee, 2001). In this context, ontologies can be seen as metadata that represent semantic of data; providing a knowledge domain standard vocabulary, like DTDs and XML Schema do. If its pages were so structured, the Web could be seen as a heterogeneous collection of autonomous databases. This suggests that techniques developed in the Database area could be useful. Database research mainly deals with efficient storage and retrieval and with powerful query languages.

- Abstract
- Notes the heightened awareness among information professionals, caused by the increasing use of the Internet, of the need to provide user freindly searching and navigation tools and the potential role of metadata in achieving this end. Concentrates on the specific formats of metadata, reviews a number of metadata formats (IAFA/WHOIS++, MARC, TEI, Dublin Core, URCs) and compares them according to the criteria of: constituency; ease of creation; content; associated Internet protocols; and progress towards international standard status

- Abstract
- The Day was held in Oct 96 to inform about developments in dexcription of electronic documents. Metadata are necessary to aid handling of electronic network resources. A workshop in Dublin Mar 95 compiled 13 elements needed to identify a document-like object, while the Warwick workshop Apr 96 proposed a framework for electronic entries with more metadata types than the Dublin Core. The Nordic Metadata Project aims to evaluate existing metadata format; develop the Dublic Core; make conversion of the Core to the Nordic MARC format possible; and set up a metadata search service for Nordic Internet documents. At the 2nd International Conference on Conceptions of Library and Information Science, Copenhagen Oct 96 a metadata structure for research profiles on Internet homepages was proposed

- Abstract
- A 5th metadata workshop was held in Helsinki in Oct 1997, cosponsored by the National Library of Finland and OCLC, and 75 experts continued work begun in 1995 to try and reach consensus on conventions for describing resources on the Internet. Representatives of the W3C Metadata Project presented the 1st draft of a new specification for extended Web metadata: the Resource Description Framework (RDF), and demonstrated how this meets the infrastructure and encoding arrangements identified at the series of international Dublin Core workshops. W3C is an industry consortium run jointly by institutions in the USA, France and Japan, and currently has 210 members

- Abstract
- Defines metadata, which for librarians means catalogue records for printed publications, and the need for them in document retrieval. The existence of many different sources of metadata had led to a need for simpler metadata schemes and a stadardised exchange format. The 1st Metadata Workshop, held in Dublin, Ohio, reached consensus on a simple resource description record, known as the Dublin core set, with 13 elements, which can serve to unify various models. Lists institutions intending to use it. The 2nd workshop resulted in a proposal for a container record architecture comprising more and different types of metadata than a Dublin core record. The Nordic Metadata project, outlined here, aims to improve the knowledge transfer to the Nordic countries and allow them to paricipate actively in international developments
