Named a 2017 Choice Outstanding Academic Title

Featuring new developments driven by semantic technologies and digital data and information, with an accompanying website and supplementary learning materials, this remains the definitive primer on metadata for students, instructors, faculty, and professionals at all levels of experience.

This benchmark text is back in a new edition thoroughly updated to incorporate developments and changes in metadata and related domains. Zeng and Qin provide a solid grounding in the variety and interrelationships among different metadata types, offering a comprehensive look at the metadata schemas that exist in the world of library and information science and beyond. Readers will gain knowledge and an understanding of key topics such as

  • the fundamentals of metadata, including principles of metadata, structures of metadata vocabularies, and metadata descriptions;
  • metadata building blocks, from modeling to defining properties, from designing application profiles to implementing value vocabularies, and from specification generating to schema encoding, illustrated with new examples;
  • best practices for metadata as linked data, the new functionality brought by implementing the linked data principles, and the importance of knowledge organization systems;
  • resource metadata services, quality measurement, and interoperability approaches; 
  • research data management concepts like the FAIR principles, metadata publishing on the web and the recommendations by the W3C in 2017, related Open Science metadata standards such as Data Catalog Vocabulary (DCAT) version 2, and metadata-enabled reproducibility and replicability of research data;
  • standards used in libraries, archives, museums, and other information institutions, plus existing metadata standards’ new versions, such as the EAD 3, LIDO 1.1, MODS 3.7, DC Terms 2020 release coordinating its ISO 15396-2:2019, and Schema.org’s update in responding to the pandemic; and
  • newer, trending forces that are impacting the metadata domain, including entity management, semantic enrichment for the existing metadata, mashup culture such as enhanced Wikimedia contents, knowledge graphs and related processes, semantic annotations and analysis for unstructured data, and supporting digital humanities (DH) through smart data.

A supplementary website provides additional resources, including examples, exercises, main takeaways, and editable files for educators and trainers. Examination copies are available for instructors who are interested in adopting this title for course use. An e-book edition of the text will be available shortly after the print edition is published.

Praise for the second edition

"The second edition of this book represents much more than a serviceable update to the first edition, published in 2008. Zeng (Kent State Univ.) and Qin (Syracuse Univ.) have significantly revised their thinking about metadata construction, application, usability, and sustainability. As a result, the current edition of this seminal resource represents a radical and necessary shift to a richer, more comprehensive analysis of metadata and its uses ... A core reference work for all professionals and advanced students interested in the subject of metadata."
— Choice

"This is an impressive, well-written textbook for readers studying metadata. In a field that is steadily growing and changing, readers must keep abreast of the new material that appears in this edition, and not rely solely on the previous edition to inform their thinking. It is by no means an easy transition, though the authors have tried hard to include the relevant background that puts today's ideas in context. They have succeeded in making a complex subject understandable as well as anticipating future developments."
