This publication is a very accessible introduction to and exploration of the concept of metadata. The authors have extensive experience in teaching and researching metadata and generously share their expertise in metadata application design, implementation and evaluation. Metadata concepts, principles and applications, as well as trends, innovative ideas and advanced technologies are systematically considered.
The book's nine chapters are organised in four parts. Part 1, “Fundamentals of metadata”, deals with definitions, types, functions, principles and anatomy of a metadata standard. Current metadata standards, ranging from general to domain‐specific applications (such as visual resources and rights management), are also appraised. In Part 2, “Metadata building blocks”, the authors propose practical methods and techniques to be employed when faced with issues, problems and situations that might occur when applying and implementing metadata. The advice on identifying and developing suitable structures and semantics and how these impact the creation and encoding of metadata records is particularly useful. The third part, “Metadata services”, deals with current and emerging infrastructures and standards such as XML and RDF, which are utilised to ensure optimal metadata discovery by means of retrieval technologies and methods. Services' functionalities, basic components and types of models are investigated. Two chapters focus on the critical issues of measuring and evaluating metadata quality, as well as methods of ensuring and achieving interoperability. The final part, “Metadata outlook in research”, presents an overview of current metadata research, in particular research on metadata architecture, modelling and semantics. In addition, areas for further research are discussed.
Several features set this book apart from other metadata literature. Lots of figures, exhibits and tables are used to great effect to make the various technical terms and concepts easier to understand. Practical examples are used throughout to explain and illustrate theoretical concepts. Each chapter ends with a list of recommended readings and exercises. These instructional features are particularly impressive and can be utilised for self‐study or by lecturers to compile class or practical assignments. An accompanying web site (www.neal‐schuman/metadata) provides additional quizzes, sample problems and solutions, as well as hands‐on tutorials. In addition, appendices in the form of sections on metadata standards, value encoding schemes, content standards, a glossary, a comprehensive bibliography and an index enable easy navigation and reference.
In conclusion, students, lecturers and practitioners could all benefit from examining the theory, practice and helpful hints presented in this text.
