Abstract

XML Topic Maps (XTM) represent a powerful new tool for transforming the Web from a vast, chaotic sea of data into a highly usable information resource. XML Topic Maps is the first comprehensive, authoritative guide to this new technology. Edited by Jack Park, a leader of the XTM community, with contributions from leading members of the community, it covers every aspect of XML Topic Map creation and usage. Drawing on the XTM 1.0 standard, a complete XML grammar for interchanging Web-based Topic Maps, this book shows how XML Topic Maps can be utilized as an enabling technology for the new "Semantic Web," in which information is given well-defined meaning, making it possible for computers and people to cooperate more effectively than ever before. Coverage includes: creating, using, and extending XML Topic Maps; ontological engineering; and the use of XML Topic Maps to create next-generation knowledge representation systems and search tools. Park shows how to use Topic Maps to visualize data; how Topic Maps relate to RDF and semantic networks; and finally, how Topic Maps presage a profound paradigm shift in the way information is represented, shared, and learned on the Internet -- and everywhere else. For every Web designer, developer, and content specialist concerned with delivering and sharing information in more useful and meaningful forms.

Footnote

Part II consists of five papers on specific metadata standards and applications. Anita Coleman presents an element-by-element description of how to create Dublin Core metadata for Web resources to be included in a library catalog, using principles inspired by cataloging practice, in her paper "From Cataloging to Metadata: Dublin Core Records for the Library Catalog." The next three papers provide especially excellent introductory overviews of three diverse types of metadata-related standards: "Metadata Standards for Archival Control: An Introduction to EAD and EAC" by Alexander C. Thurman, "Introduction to XML" by Patrick Yott, and "METS: the Metadata Encoding and Transmission Standard" by Linda Cantara. Finally, Michael Chopey offers a superb and most useful overview of "Planning and Implementing a Metadata-Driven Digital Repository." Although all of the articles in this book contain interesting, often illuminating, and potentially useful information, not all serve equally well as introductory material for working catalogers not already familiar with metadata. It would be difficult to consider this volume, taken as a whole, as truly a "primer" for catalog librarians, as the subtitle implies. The content of the articles is too much a mix of introductory essays and original research, some of it at a relatively more advanced level. The collection does not approach the topic in the kind of coherent, systematic, or comprehensive way that would be necessary for a true "primer" or introductory textbook. While several of the papers would be quite appropriate for a primer, such a text would need to include, among other things, coverage of other metadata schemes and protocols such as TEI, VRA, and OAI, which are missing here. That having been said, however, Dr. Smiraglia's excellent introduction to the volume itself serves as a kind of concise, well-written "mini-primer" for catalogers new to metadata. It succinctly covers definitions of metadata, basic concepts, content designation and markup languages, metadata for resource description, including short overviews of TEI, DC, EAD, and AACR2/MARC21, and introduces the papers included in the book. In the conclusion to this essay, Dr. Smiraglia says about the book: "In the end the contents go beyond the definition of primer as `introductory textbook.' But the authors have collectively compiled a thought-provoking volume about the uses of metadata" (p. 15). This is a fair assessment of the work taken as a whole. In this reviewer's opinion, there is to date no single introductory textbook on metadata that is fully satisfactory for both working catalogers and for library and information science (LIS) students who may or may not have had exposure to cataloging. But there are a handful of excellent books that serve different aspects of that function. These include the following recent publications:
