    Abstract
    Metadata (structured information about an object or collection of objects) is increasingly important to libraries, archives, and museums. And although librarians are familiar with a number of issues that apply to creating and using metadata (e.g., authority control, controlled vocabularies, etc.), the world of metadata is nonetheless different than library cataloging, with its own set of challenges. Therefore, whether you are new to these concepts or quite experienced with classic cataloging, this short (20 pages) introductory paper on metadata can be helpful

    Abstract
    A system of library classification that flashed across the inquiring mind of young Melvil Louis Kossuth Dewey (known as Melvil Dewey) in 1873 is still the most popular classification scheme.. The modern library classification begins with Dewey Decimal Classification (DDC). Melvil Dewey devised DDC in 1876. DDC has is credit of 128 years of boudless success. The DDC is being taught as a practical subject throughout the world and it is being used in majority of libraries in about 150 countries. This is the result of continuous revision that 22nd Edition of DDC has been published in July 2003. No other classification scheme has published so many editions. Some welcome changes have been made in DDC 22. To reduce the Christian bias in 200 religion, the numbers 201 to 209 have been devoted to specific aspects of religion. In the previous editions these numbers were devoted to Christianity. to enhance the classifier's efficiency, Table 7 has been removed from DDC 22 and the provision of adding group of persons is made by direct use of notation already available in schedules and in notation -08 from Table 1 Standard Subdivision. The present book is an attempt to explain, with suitable examples, the salient provisions of DDC 22. The book is written in simple language so that the students may not face any difficulty in understanding what is being explained. The examples in the book are explained in a step-by-step procedure. It is hoped that this book will prove of great help and use to the library professionals in general and library and information science students in particular.

    "The contents of the book cover: This book is intended as an introduction to the Dewey Decimal Classification, edition 22. It is not a substitute for it, and I assume that you have it, all four volumes of it, by you while reading the book. I have deliberately included only a short section an WebDewey. This is partly because WebDewey is likely to change more frequently than the printed version, but also because this book is intended to help you use the scheme regardless of the manifestation in which it appears. If you have a subscription to WebDewey and not the printed volumes you may be able to manage with that, but you may then find my references to volumes and page numbers baffling. All the examples and exercises are real; what is not real is the idea that you can classify something without seeing more than the title. However, there is nothing that I can do about this, and I have therefore tried to choose examples whose titles adequately express their subject-matter. Sometimes when you look at the 'answers' you may feel that you have been cheated, but I hope that this will be seldom. Two people deserve special thanks. My colleague Vanda Broughton has read drafts of the book and made many suggestions. Ross Trotter, chair of the CILIP Dewey Decimal Classification Committee, who knows more about Dewey than anyone in Britain today, has commented extensively an it and as far as possible has saved me from error, as well as suggesting many improvements. What errors remain are due to me alone. Thanks are also owed to OCLC Online Computer Library Center, for permission to reproduce some specimen pages of DDC 22. Excerpts from the Dewey Decimal Classification are taken from the Dewey Decimal Classification and Relative Index, Edition 22 which is Copyright 2003 OCLC Online Computer Library Center, Inc.

    Rez. in: XML Magazin und Web Services 2003, H.1, S.14 (S. Meyen): "Seit dem 22. Februar 1999 ist das Resource Description Framework (RDF) als W3C-Empfehlung verfügbar. Doch was steckt hinter diesem Standard, der das Zeitalter des Semantischen Webs einläuten soll? Was RDF bedeutet, wozu man es einsetzt, welche Vorteile es gegenüber XML hat und wie man RDF anwendet, soll in diesem Artikel erläutert werden. Schlägt man das Buch auf und beginnt, im EinleitungsKapitel zu schmökern, fällt sogleich ins Auge, dass der Leser nicht mit Lektionen im Stile von "bei XML sind die spitzen Klammern ganz wichtig" belehrt wird, obgleich es sich um ein Buch für Anfänger handelt. Im Gegenteil: Es geht gleich zur Sache und eine gesunde Mischung an Vorkenntnissen wird vorausgesetzt. Wer sich heute für XML interessiert, der hat ja mit 99-prozentiger Wahrscheinlichkeit schon seine einschlägigen Erfahrungen mit HTML und dem Web gemacht und ist kein Newbie in dem Reich der spitzen Klammern und der (einigermaßen) wohlformatierten Dokumente. Und hier liegt eine deutliche Stärke des Werkes Helmut Vonhoegens, der seinen Einsteiger-Leser recht gut einzuschätzen weiß und ihn daher praxisnah und verständlich ans Thema heranführt. Das dritte Kapitel beschäftigt sich mit der Document Type Definition (DTD) und beschreibt deren Einsatzziele und Verwendungsweisen. Doch betont der Autor hier unablässig die Begrenztheit dieses Ansatzes, welche den Ruf nach einem neuen Konzept deutlich macht: XML Schema, welches er im folgenden Kapitel darstellt. Ein recht ausführliches Kapitel widmet sich dann dem relativ aktuellen XML Schema-Konzept und erläutert dessen Vorzüge gegenüber der DTD (Modellierung komplexer Datenstrukturen, Unterstützung zahlreicher Datentypen, Zeichenbegrenzungen u.v.m.). XML Schema legt, so erfährt der Leser, wie die alte DTD, das Vokabular und die zulässige Grammatik eines XML-Dokuments fest, ist aber seinerseits ebenfalls ein XML-Dokument und kann (bzw. sollte) wie jedes andere XML auf Wohlgeformtheit überprüft werden. Weitere Kapitel behandeln die Navigations-Standards XPath, XLink und XPointer, Transformationen mit XSLT und XSL und natürlich die XML-Programmierschnittstellen DOM und SAX. Dabei kommen verschiedene Implementierungen zum Einsatz und erfreulicherweise werden Microsoft-Ansätze auf der einen und Java/Apache-Projekte auf der anderen Seite in ungefähr vergleichbarem Umfang vorgestellt. Im letzten Kapitel schließlich behandelt Vonhoegen die obligatorischen Web Services ("Webdienste") als Anwendungsfall von XML und demonstriert ein kleines C#- und ASP-basiertes Beispiel (das Java-Äquivalent mit Apache Axis fehlt leider). "Einstieg in XML" präsentiert seinen Stoff in klar verständlicher Form und versteht es, seine Leser auf einem guten Niveau "abzuholen". Es bietet einen guten Überblick über die Grundlagen von XML und kann - zumindest derzeit noch - mit recht hoher Aktualität aufwarten."

    In Chapter 10, "Controlled indexing languages," Professor Broughton states that a classification scheme is truly a language "since it permits communication and the exchange of information" (p. 89), a Statement with which this reviewer wholly agrees. Chapter 11, however, "Word-based approaches to retrieval," moves us to a different field altogether, offering only a narrow view of the whole world of controlled indexing languages such as thesauri, and presenting disconnected discussions of alphabetical filing, form and structure of subject headings, modern developments in alphabetical subject indexing, etc. Chapters 12 and 13 focus an the Library of Congress Subject Headings (LCSH), without even a passing reference to existing subject headings lists in other languages (French RAMEAU, German SWK, etc.). If it is not surprising to see a section on subject headings in a book on classification, the two subjects being taught together in most library schools, the location of this section in the middle of this particular book is more difficult to understand. Chapter 14 brings the reader back to classification, for a discussion of essentials of classification scheme application. The following five chapters present in turn each one of the three major and currently used bibliographic classification schemes, in order of increasing complexity and difficulty of application. The Library of Congress Classification (LCC), the easiest to use, is covered in chapters 15 and 16. The Dewey Decimal Classification (DDC) deserves only a one-chapter treatment (Chapter 17), while the functionalities of the Universal Decimal Classification (UDC), which Professor Broughton knows extremely well, are described in chapters 18 and 19. Chapter 20 is a general discussion of faceted classification, on par with the first seven chapters for its theoretical content. Chapter 21, an interesting last chapter on managing classification, addresses down-to-earth matters such as the cost of classification, the need for re-classification, advantages and disadvantages of using print versions or e-versions of classification schemes, choice of classification scheme, general versus special scheme. But although the questions are interesting, the chapter provides only a very general overview of what appropriate answers might be. To facilitate reading and learning, summaries are strategically located at various places in the text, and always before switching to a related subject. Professor Broughton's choice of examples is always interesting, and sometimes even entertaining (see for example "Inside out: A brief history of underwear" (p. 71)). With many examples, however, and particularly those that appear in the five chapters an classification scheme applications, the novice reader would have benefited from more detailed explanations. On page 221, for example, "The history and social influence of the potato" results in this analysis of concepts: Potato - Sociology, and in the UDC class number: 635.21:316. What happened to the "history" aspect? Some examples are not very convincing: in Animals RT Reproduction and Art RT Reproduction (p. 102), the associative relationship is not appropriate as it is used to distinguish homographs and would do nothing to help either the indexer or the user at the retrieval stage.

    Chapter 2 examines the variety and breadth of DL implementations and collections through a well-balanced selection of 20 DLs. The authors make a useful classification of the various types of DLs into seven categories and give a brief synopsis of two or three examples from each category. These categories include historical, national, and university DLs, as well as DLs for special materials and research. Chapter 3 examines research efforts in digital libraries, concentrating an the three eLib initiatives in the UK and the two Digital Libraries Initiatives in the United States. The chapter also offers some details an joint research between the UK and the United States (the NSF/JISC jointly funded programs), Europe, Canada, Australia, and New Zealand. While both of these chapters do an admirable job of surveying the DL landscape, the breadth and variety of materials need to be encapsulated in a coherent summary that illustrates the commonality of their approaches and their key differences that have been driven by aspects of their collections and audience. Unfortunately, this summary aspect is lacking here and elsewhere in the book. Chapter 2 does an admirable job of DL selection that showcases the variety of existing DLs, but 1 feel that Chapter 3's selection of research projects could be improved. The chapter's emphasis is clearly an UK-based research, devoting nine pages to it compared to six for EU-funded projects. While this emphasis could be favorable for UK courses, it hampers the chances of the text's adoption in other courses internationally. Chapter 4 begins the core part of the book by examining the DL from a design perspective. As a well-designed DL encompasses various practical and theoretical considerations, the chapter introduces much of the concepts that are elaborated an in later chapters. The Kahn/Wilensky and Lagoze/Fielding architectures are summarized in bullet points, and specific aspects of these frameworks are elaborated on. These include the choice between a federated or centralized search architecture (referencing Virginia Tech's NDLTD and Waikato's Greenstone) and level of interoperability (discussing UNIMARC and metadata harvesting). Special attention is paid to hybrid library design, with references to UK projects. A useful summary of recommended standards for DL design concludes the chapter.
