The next chapter introduces resource description framework (RDF) and RDF schema (RDFS). Unlike XML, RDF provides a foundation for expressing the semantics of dada: it is a standard dada model for machine-processable semantics. Resource description framework schema offers a number of modeling primitives for organizing RDF vocabularies in typed hierarchies. In addition to RDF and RDFS, a query language for RDF, i.e. RQL. is introduced. This chapter and the next chapter are two of the most important chapters in the book. Chapter 4 presents another language called Web Ontology Language (OWL). Because RDFS is quite primitive as a modeling language for the Web, more powerful languages are needed. A richer language. DAML+OIL, is thus proposed as a joint endeavor of the United States and Europe. OWL takes DAML+OIL as the starting point, and aims to be the standardized and broadly accepted ontology language. At the beginning of the chapter, the nontrivial relation with RDF/RDFS is discussed. Then the authors describe the various language elements of OWL in some detail. Moreover, Appendix A contains an abstract OWL syntax. which compresses OWL and makes OWL much easier to read. Chapter 5 covers both monotonic and nonmonotonic rules. Whereas the previous chapter's mainly concentrate on specializations of knowledge representation, this chapter depicts the foundation of knowledge representation and inference. Two examples are also givwn to explain monotonic and non-monotonic rules, respectively. "To get the most out of the chapter. readers had better gain a thorough understanding of predicate logic first. Chapter 6 presents several realistic application scenarios to which the Semantic Web technology can be applied. including horizontal information products at Elsevier, data integration at Audi, skill finding at Swiss Life, a think tank portal at EnerSearch, e-learning. Web services, multimedia collection indexing, online procurement, raid device interoperability. These case studies give us some real feelings about the Semantic Web.

Abstract

Mit der ersten Auflage von Basiswissen RDA lag erstmals ein deutschsprachiges Lehrbuch für das neue, internationale Katalogisierungsregelwerk RDA (Resource Description and Access) vor. Seither wurde nicht nur das Regelwerk selbst an vielen Stellen verändert, sondern auch die deutschsprachigen Anwendungsrichtlinien wurden erheblich erweitert und verfeinert - nicht zuletzt aufgrund der Praxiserfahrungen seit dem Beginn der aktiven Katalogisierung mit RDA. Die überarbeitete und erweiterte Neuauflage - präsentiert die Katalogisierungsregeln auf dem aktuellen Stand von 2017 - bietet an vielen Stellen zusätzliche Details und Erläuterungen - geht besonders auf typische Fragen und Probleme ein, die beim Katalogisieren mit RDA auftreten - wurde um Beispiele und Erklärungen für verschiedene Themenbereiche erweitert (u.a. Reproduktionen, E-Books, Sprachkurse) - behandelt auch das neue theoretische Modell IFLA LRM und die geplante Weiterentwicklung von RDA Die zweite Auflage von Basiswissen RDA ist ein unverzichtbarer Begleiter für Studierende, Auszubildende und Beschäftigte in Bibliotheken, die mit RDA arbeiten. Das Lehrbuch unterstützt nicht nur beim Anfertigen von korrekten Katalogisaten, sondern auch dabei, das neue Regelwerk zu verstehen.

Footnote

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.
Essential Classification is also an exercise book. Indeed, it contains a number of practical exercises and activities in every chapter, along with suggested answers. Unfortunately, the answers are too often provided without the justifications and explanations that students would no doubt demand. The author has taken great care to explain all technical terms in her text, but formal definitions are also gathered in an extensive 172-term Glossary; appropriately, these terms appear in bold type the first time they are used in the text. A short, very short, annotated bibliography of standard classification textbooks and of manuals for the use of major classification schemes is provided. A detailed 11-page index completes the set of learning aids which will be useful to an audience of students in their effort to grasp the basic concepts of the theory and the practice of document classification in a traditional environment. Essential Classification is a fine textbook. However, this reviewer deplores the fact that it presents only a very "traditional" view of classification, without much reference to newer environments such as the Internet where classification also manifests itself in various forms. In Essential Classification, books are always used as examples, and we have to take the author's word that traditional classification practices and tools can also be applied to other types of documents and elsewhere than in the traditional library. Vanda Broughton writes, for example, that "Subject headings can't be used for physical arrangement" (p. 101), but this is not entirely true. Subject headings can be used for physical arrangement of vertical files, for example, with each folder bearing a simple or complex heading which is then used for internal organization. And if it is true that subject headings cannot be reproduced an the spine of [physical] books (p. 93), the situation is certainly different an the World Wide Web where subject headings as metadata can be most useful in ordering a collection of hot links. The emphasis is also an the traditional paperbased, rather than an the electronic version of classification schemes, with excellent justifications of course. The reality is, however, that supporting organizations (LC, OCLC, etc.) are now providing great quality services online, and that updates are now available only in an electronic format and not anymore on paper. E-based versions of classification schemes could be safely ignored in a theoretical text, but they have to be described and explained in a textbook published in 2005. One last comment: Professor Broughton tends to use the same term, "classification" to represent the process (as in classification is grouping) and the tool (as in constructing a classification, using a classification, etc.). Even in the Glossary where classification is first well-defined as a process, and classification scheme as "a set of classes ...", the definition of classification scheme continues: "the classification consists of a vocabulary (...) and syntax..." (p. 296-297). Such an ambiguous use of the term classification seems unfortunate and unnecessarily confusing in an otherwise very good basic textbook an categorization of concepts and subjects, document organization and subject representation."
