    Abstract
    To improve searching, filtering and processing of information on the Web, a common effort is made in the direction of metadata, defined as machine understandable information about Web resources or other things. In particular, the eXtensible Markup Language (XML) aims at providing a common syntax to emerging metadata formats. Proposes the Structured Graph Format (SGF) an XML compliant markup language based on structured graphs, for capturing Web sites' structure. Presents SGMapper, a client-site tool, which aims to facilitate navigation in large Web sites by generating highly interactive site maps using SGF metadata

    Abstract
    Highlights 2 major problems of the WWW metadata: it will take some time before a reasonable number of people start using metadata to provide a better Web classification, and that no one can guarantee that a majority of the Web objects will be ever properly classified via metadata. Addresses the problem of how to cope with intrinsic limits of Web metadata, proposes a method to solve these problems and show evidence of its effectiveness. Examines the important problem of what is the required critical mass in the WWW for metadata in order for it to be really useful

    Abstract
    Examines techniques that discover features in sets of pre-categorized documents, such that similar documents can be found on the WWW. Examines techniques which will classifiy training examples with high accuracy, then explains why this is not necessarily useful. Describes a method for extracting word clusters from the raw document features. Results show that the clustering technique is successful in discovering word groups in personal Web pages which can be used to find similar information on the WWW

    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
    Reports results of a study to evaluate the effectiveness of using the HTML META tag to improve retrieval of World Wide Web documents through Internet search engines. 20 documents were created in 5 subject areas: agricultural trade; farm business statistics; poultry statistics; vegetable statistics; and cotton statistics. 4 pages were created in each subject area: one with no META tags, one with a META tag using the keywords attribute, one with a META tag using the description attribute, and one with META tags using both the keywords and description attributes. Searches were performed in Alta Vista and Infoseek to find terms common to all pages as well as for each keyword term contained in the META tag. Analysis of the searches suggests that use of the keywords attribute in a META tag substantially improves accessibility while use of the description attribute alone does not. Concludes that HTML document authors should consider using keywords attribute META tags and suggests that more search engines index the META tag to improve resource discovery

    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 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
    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
    Bibliografische Daten, Normdaten und Metadaten im Semantic Web - Konzepte der Bibliografischen Kontrolle im Wandel. Der Titel dieser Arbeit zielt in ein essentielles Feld der Bibliotheks- und Informationswissenschaft, die Bibliografische Kontrolle. Als zweites zentrales Konzept wird der in der Weiterentwicklung des World Wide Webs (WWW) bedeutsame Begriff des Semantic Webs genannt. Auf den ersten Blick handelt es sich hier um einen ungleichen Wettstreit. Auf der einen Seite die Bibliografische Kontrolle, welche die Methoden und Mittel zur Erschließung von bibliothekarischen Objekten umfasst und traditionell in Form von formal-inhaltlichen Surrogaten in Katalogen daherkommt. Auf der anderen Seite das Buzzword Semantic Web mit seinen hochtrabenden Konnotationen eines durch Selbstreferenzialität "bedeutungstragenden", wenn nicht sogar "intelligenten" Webs. Wie kamen also eine wissenschaftliche Bibliothekarin und ein Mitglied des World Wide Web Consortiums 2007 dazu, gemeinsam einen Aufsatz zu publizieren und darin zu behaupten, das semantische Netz würde ein "bibliothekarischeres" Netz sein? Um sich dieser Frage zu nähern, soll zunächst kurz die historische Entwicklung der beiden Informationssphären Bibliothek und WWW gemeinsam betrachtet werden. Denn so oft - und völlig zurecht - die informationelle Revolution durch das Internet beschworen wird, so taucht auch immer wieder das Analogon einer weltweiten, virtuellen Bibliothek auf. Genauer gesagt, nahmen die theoretischen Überlegungen, die später zur Entwicklung des Internets führen sollten, ihren Ausgangspunkt (neben Kybernetik und entstehender Computertechnik) beim Konzept des Informationsspeichers Bibliothek.

    Abstract
    In order to test the power of metadata on information retrieval, an experiment was designed and conducted on a group of 7 graduate students using the Dublin Core as the cataloguing metadata. Results show that, on average, the retrieval error rate is only 2.9 per cent for the MES system (http://140.136.85.194), which utilizes the Dublin Core to describe the documents on the World Wide Web, in contrast to 20.7 per cent for the 7 famous search engines including HOTBOT, GAIS, LYCOS, EXCITE, INFOSEEK, YAHOO, and OCTOPUS. The very low error rate indicates that the users can use the information of the Dublin Core to decide whether to retrieve the documents or not

    Abstract
    Four sets of Web pages previously visited in the summer of 2000 were revisited one year later. Of 707 pages containing metatag descriptions in 2000, 586 retained descriptions in 2001, and, of 1,230 pages lacking descriptions in 2000, 101 had descriptions in 2001. Home pages appeared to both lose and change descriptions more than other pages, with about 19% of descriptions changed in the two sets where home pages predominated versus about 12% in the other two sets. About two-thirds of changes involved minor revisions, and changes fell into a wide variety of categories. Some implications for software to assist in description revision are discussed

    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 PowerPoint presentations from this one-day workshop on emerging metadata practices are available at this web site. Topics include metadata quality, interoperability, linking metadata, metadata for image collections, RSS, MODS, METS, and MPEG-21. Contributors include representatives from OCLC, CrossRef, the Library of Congress, universities and the private sector. Given the wide range of presentations, if you're interested in metadata you can likely find something of interest here, but no single topic is explored in much depth, and you are sometimes left wondering what the speaker said about a particular slide if there are no accompanying notes.

    Abstract
    It is apparent that, despite the common reference to the World Wide Web as a "digital library", it lacks any of the organising features which would be expected from a library. The rate of growth of Web resources is such that they have grown, and continue to grow, beyond the ability of human intervention to catalogue them or control access to them. The software tools which have so far emerged to assist searching are inadequate for the task, but it is hoped that a development in standards will lead to documents being created with the "hooks" in place, which will facilitate their retrieval by tools yet to be developed. Dublin Core metadata appears to be the optimum such emergent standard, and its use is to be encouraged among Web authors.

    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
    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.
