    Abstract
    This paper presents findings of a survey an the state of cataloging and metadata education. in ALA-accredited library and information science progranis in North America. The survey was conducted in response to Action Item 5.1 of the "Bibliographic Control of Web Resources: A Library of Congress Action Plan," which focuses an providing metadata education to new LIS professionals. The study found LIS programs increased their reliance an introductory courses to cover cataloging and metadata, but fewer programs than before had a cataloging course requirement. The knowledge of cataloging delivered in introductory courses was basic, and the coverage of metadata was limited to an overview. Cataloging courses showed similarity in coverage and practice and focused an print mater!als. Few cataloging educators provided exercises in metadata record creation using non-AACR standards. Advanced cataloging courses provided in-depth coverage of subject cataloging and the cataloging of nonbook resources, but offered very limited coverage of metadata. Few programs offered full courses an metadata, and even fewer offered advanced metadata courses. Metadata topics were well integrated into LIS curricula, but coverage of metadata courses varied from program to program, depending an the interests of instructors. Educators were forward-looking and agreed an the inclusion of specific knowledge and skills in metadata instruction. A series of actions were proposed to assist educators in providing students with competencies in cataloging and metadata.

    Abstract
    Information subject gateways provide targeted discovery services for their users, giving access to Web resources selected according to quality and subject coverage criteria. Information gateways recognise that they must collaborate on a wide range of issues relating to content to ensure continued success. This report is informed by discussion of content activities at the 1999 Imesh Workshop. The author considers the implications for subject based gateways of co-operation regarding coverage policy, creation of metadata, and provision of searching and browsing across services. Other possibilities for co-operation include working more closely with information providers, and diclosure of information in joint metadata registries

    Abstract
    Metadata is used to organize and control a wide range of different types of information object collections, most of which are accessed via the World Wide Web. This chapter presents a brief introduction to the purpose of metadata and how it has developed, and an overview of the steps to be taken and the functional expertise required in planning for and implementing the creation, storage, and use of metadata for resource discovery in a local repository of information objects.

    Abstract
    Das »Semantic Web« bildet einen der wichtigsten, aktuellen Trends in der Weiterentwicklung des World Wide Web. Ehrgeizige Vision dieser nächsten Generation des WWW ist es, durch semantische Anreicherung von Information eine neue Qualität in der Bereitstellung von Inhalten und Diensten zu erreichen und vollständig neue Anwendungsmöglichkeiten für das Web zu eröffnen. Wichtige Ziele der Entwicklung des Semantic Web sind dabei die verbesserte Unterstützung von Kooperation zwischen Menschen und Computern und die intelligente Assistenz bei der Durchführung von Aufgaben in kooperativen verteilten Informationsumgebungen. Schlüssel zur Erreichung dieser Ziele sind die Anreicherung von Daten im Web mit Metadaten, welche diese Daten in einen semantischen Kontext einbetten. Diese Kontextinformation wird durch Software-Anwendungen interpretiert und zur Informationsfilterung, Verfeinerung von Anfragen und zur Bereitstellung intelligenter Assistenten verwendet. Eine große Herausforderung stellt dabei die geeignete Modellierung und Beschreibung des Kontexts dar. Diese muss eine automatische, globale Interpretation ermöglichen, ohne dass auf ein allgemeingültiges semantisches Beschreibungsschema zurückgegriffen werden kann. Die Vereinbarung eines solchen allgemeingültigen Schemas ist in einem derart umfangreichen, heterogenen und autonomen Rahmen, wie ihn das WWW darstellt, nicht möglich.

    Abstract
    The Dublin Core is an international standard for describing and cataloging all kinds of information resources: books, articles, videos, and World Wide Web (web) resources. Sixteen Dublin Core (DC) elements and the steps for cataloging web resources using these elements and minimal controlled values are discussed, general guidelines for metadata creation are highlighted, a worksheet is provided to create the DC metadata records for the library catalog, and sample resource descriptions in DC are included.

    Abstract
    Metadata is of paramount importance for persons, organizations, and endeavors of every dimension that are increasingly turning to the World Wide Web (hereafter referred to as the Web) as a chief conduit for accessing and disseminating information. This is evidenced by the development and implementation of metadata schemas supporting projects ranging from restricted corporate intranets, data warehouses, and consumer-oriented electronic commerce enterprises to freely accessible digital libraries, educational initiatives, virtual museums, and other public Web sites. Today's metadata activities are unprecedented because they extend beyond the traditional library environment in an effort to deal with the Web's exponential growth. This article considers metadata in today's Web environment. The article defines metadata, examines the relationship between metadata and cataloging, provides definitions for key metadata vocabulary terms, and explores the topic of metadata generation. Metadata is an extensive and expanding subject that is prevalent in many environments. For practical reasons, this article has elected to concentrate an the information resource domain, which is defined by electronic textual documents, graphical images, archival materials, museum artifacts, and other objects found in both digital and physical information centers (e.g., libraries, museums, record centers, and archives). To show the extent and larger application of metadata, several examples are also drawn from the data warehouse, electronic commerce, open source, and medical communities.

    Abstract
    Dublin Core is often presented as a modern form of catalog card -- a set of elements (and now qualifiers) that describe resources in a complete package. Sometimes it is proposed as an exchange format for sharing records among multiple collections. The founding principle that "every element is optional and repeatable" reinforces the notion that a Dublin Core description is to be taken as a whole. This paper, in contrast, is based on a much different premise: Dublin Core is a language. More precisely, it is a small language for making a particular class of statements about resources. Like natural languages, it has a vocabulary of word-like terms, the two classes of which -- elements and qualifiers -- function within statements like nouns and adjectives; and it has a syntax for arranging elements and qualifiers into statements according to a simple pattern. Whenever tourists order a meal or ask directions in an unfamiliar language, considerate native speakers will spontaneously limit themselves to basic words and simple sentence patterns along the lines of "I am so-and-so" or "This is such-and-such". Linguists call this pidginization. In such situations, a small phrase book or translated menu can be most helpful. By analogy, today's Web has been called an Internet Commons where users and information providers from a wide range of scientific, commercial, and social domains present their information in a variety of incompatible data models and description languages. In this context, Dublin Core presents itself as a metadata pidgin for digital tourists who must find their way in this linguistically diverse landscape. Its vocabulary is small enough to learn quickly, and its basic pattern is easily grasped. It is well-suited to serve as an auxiliary language for digital libraries. This grammar starts by defining terms. It then follows a 200-year-old tradition of English grammar teaching by focusing on the structure of single statements. It concludes by looking at the growing dictionary of Dublin Core vocabulary terms -- its registry, and at how statements can be used to build the metadata equivalent of paragraphs and compositions -- the application profile.

    Abstract
    Die seit Mitte der goer Jahre des letzten Jahrhunderts durch das Internet und vor allem durch das World Wide Web (WWW) entstandenen neuen Kommunikations- und Publikationsmöglichkeiten stellen die mit der Sammlung, Erschließung und Nutzbarmachung von Veröffentlichungen beauftragten wissenschaftlichen Bibliotheken vor neue Herausforderungen. Netzpublikationen erfordern die Überprüfung und Anpassung bestehender Methoden und Geschäftsgänge. Neben den bibliothekarischen Verfahren haben sich im WWW neue Vorgehensweisen herausgebildet. Um die Suche, die Identifikation und den Zugriff auf Netzpublikationen zu unterstützen, werden strukturierte Daten beigegeben: Metadaten. Außer den zum Auffinden der Ressourcen notwendigen Metadaten spielen weitere Arten von Metadaten für Netzpublikationen eine zunehmend wichtige Rolle.

    Abstract
    The Metadata Encoding and Transmission Standard (METS) is a data communication standard for encoding descriptive, administrative, and structural metadata regarding objects within a digital library, expressed using the XML Schema Language of the World Wide Web Consortium. An initiative of the Digital Library Federation, METS is under development by an international editorial board and is maintained in the Network Development and MARC Standards Office of the Library of Congress. Designed in conformance with the Open Archival Information System (OAIS) Reference Model, a METS document encapsulates digital objects and metadata as Information Packages for transmitting and/or exchanging digital objects to and from digital repositories, disseminating digital objects via the Web, and archiving digital objects for long-term preservation and access. This paper presents an introduction to the METS standard and through illustrated examples, demonstrates how to build a METS document.

    Abstract
    This entry is a personal remembrance of the emergence and evolution of the Dublin Core Metadata Initiative from its inception in a 1994 invitational workshop to its current state as an international open standards community. It describes the context of resource description in the early days of the World Wide Web, and discusses both social and technical engineering brought to bear on its development. Notable in this development is the international character of the workshop and conference series, and the diverse spectrum of expertise from many countries that contributed to the effort. The Dublin Core began as a consensus-driven community that elaborated a set of resource description principles that served a broad spectrum of users and applications. The result has been an architecture for metadata that informs most Web-based resource description efforts. Equally important, the Dublin Core has become the leading community of expertise, practice, and discovery that continues to explore the borders between the ideal and the practical in the description of digital information assets.

    Abstract
    First generation scholarly research on the Web lacked a firm system of authority control. Second generation Web research is beginning to model subject access with library science principles of bibliographic control and cataloguing. Harnessing the Web and organising the intellectual content with standards and controlled vocabulary provides precise search and retrieval capability, increasing relevance and efficient use of technology. Dublin Core metadata standards permit a full evaluation and cataloguing of Web resources appropriate to highly specific research needs and discovery. Current research points to a type of structure based on a system of faceted classification. This system allows the semantic and syntactic relationships to be defined. Controlled vocabulary, such as the Library of Congress Subject Headings, can be assigned, not in a hierarchical structure, but rather as descriptive facets of relating concepts. Web design features such as this are adding value to discovery and filtering out data that lack authority. The system design allows for scalability and extensibility, two technical features that are integral to future development of the digital library and resource discovery.

    Abstract
    With the aim of building a "Semantic Web", the content of the documents must be explicitly represented through metadata in order to enable contents-guided search. Our approach is to exploit a standard language (RDF, recommended by W3C) for expressing such metadata and to interpret these metadata in conceptual graphs (CG) in order to exploit querying and inferencing capabilities enabled by CG formalism. The paper presents our mapping of RDF into CG and its interest in the context of the semantic Web

    Abstract
    The current library bibliographic infrastructure was constructed in the early days of computers - before the Web, XML, and a variety of other technological advances that now offer new opportunities. General requirements of a modern metadata infrastructure for libraries are identified, including such qualities as versatility, extensibility, granularity, and openness. A new kind of metadata infrastructure is then proposed that exhibits at least some of those qualities. Some key challenges that must be overcome to implement a change of this magnitude are identified.

    Abstract
    With the explosion of digitized resources accessible via networked information systems, and the corresponding proliferation of general purpose and domain-specific schemes, metadata have assumed a special prominence. While recent work emanating from the World Wide Web Consortium (W3C) has focused on the Resource Description Framework (RDF) to support the interoperability of metadata standards - thus converting metatags from diverse domains from merely "machine-readable" to "machine-understandable" - the next iteration, to "human-understandable," remains a challenge. This apparent gap provides a framework for three-phase research (Howarth, 1999) to develop a tool which will provide a "human-understandable" front-end search assist to any XML-compliant metadata scheme. Findings from phase one, the analyses and mapping of seven metadata schemes, identify the particular challenges of designing a common "namespace", populated with element tags which are appropriately descriptive, yet readily understood by a lay searcher, when there is little congruence within, and a high degree of variability across, the metadata schemes under study. Implications for the subsequent design and testing of both the proposed "metalevel ontology" (phase two), and the prototype search assist tool (phase three) are examined

    Abstract
    Much research has focused on the problem of knowledge accessibility, sharing and reuse. Specific languages (e.g. KIF, CG, RDF) and ontologies have been proposed. Common characteristics, conventions or ontological distinctions are beginning to emerge. Since knowledge providers (humans and software agents) must follow common conventions for the knowledge to be widely accessed and re-used, we propose lexical, structural, semantic and ontological conventions based on various knowledge representation projects and our own research. These are minimal conventions that can be followed by most and cover the most common knowledge representation cases. However, agreement and refinements are still required. We also show that a notation can be both readable and expressive by quickly presenting two new notations -- Formalized English (FE) and Frame-CG (FCG) - derived from the CG linear form [9] and Frame-Logics [4]. These notations support the above conventions, and are implemented in our Web-based knowledge representation and document indexation tool, WebKB¹ [7]

    Abstract
    This paper presents an approach for integrating multiple sources of semantics for the creating metadata. A new framework is proposed to define topics and themes with both manually and automatically generated terms. The automatically generated terms include: terms from a semantic analysis of the collections and terms from previous user's queries. An interface is developed to facilitate the creation and use of such topics and themes for metadata creation. The framework and the interface promote human-computer collaboration in metadata creation. Several principles underlying such approach are also discussed.

    Abstract
    Folksonomy is the result of describing Web resources with tags created by Web users. Although it has become a popular application for the description of resources, in general terms Folksonomies are not being conveniently integrated in metadata. However, if the appropriate metadata elements are identified, then further work may be conducted to automatically assign tags to these elements (RDF properties) and use them in Semantic Web applications. This article presents research carried out to continue the project Kinds of Tags, which intends to identify elements required for metadata originating from folksonomies and to propose an application profile for DC Social Tagging. The work provides information that may be used by software applications to assign tags to metadata elements and, therefore, means for tags to be conveniently gathered by metadata interoperability tools. Despite the unquestionably high value of DC and the significance of the already existing properties in DC Terms, the pilot study show revealed a significant number of tags for which no corresponding properties yet existed. A need for new properties, such as Action, Depth, Rate, and Utility was determined. Those potential new properties will have to be validated in a later stage by the DC Social Tagging Community.

    Abstract
    HTML has reinvented itself as an XML application. The working draft of the latest version, XHTML 2.0, is causing controversy due to its lack of backward compatibility and the deprecation - and in some cases disappearance - of some popular tags. But is this commotion distracting us from the big picture of what XHTML has to offer? Where is HTML going? And is it taking the Web community with it?

    Abstract
    This report introduces the Dublin Core Microformats (DCMF) project, a new way to use the DC element set within X/HTML. The DC microformats encode explicit semantic expressions in an X/HTML webpage, by using a specific list of terms for values of the attributes "rev" and "rel" for <a> and <link> elements, and "class" and "id" of other elements. Microformats can be easily processed by user agents and software, enabling a high level of interoperability. These characteristics are crucial for the growing number of social applications allowing users to participate in the Web 2.0 environment as information creators and consumers. This report reviews the origins of microformats; illustrates the coding of DC microformats using the Dublin Core Metadata Gen tool, and a Firefox extension for extraction and visualization; and discusses the benefits of creating Web services utilizing DC microformats.
