Abstract

More and more libraries, archives, and museums are creating online collections of digitized resources. Where can those charged with organizing these new collections turn for guidance on the actual practice of metadata design and creation? "Metadata for Digital Collections: A How-to-do-it Manual" is suitable for libraries, archives, and museums. This practical, hands-on volume will make it easy for readers to acquire the knowledge and skills they need, whether they use the book on the job or in a classroom. Author Steven Miller introduces readers to fundamental concepts and practices in a style accessible to beginners and LIS students, as well as experienced practitioners with little metadata training. He also takes account of the widespread use of digital collection management systems such as CONTENTdm. Rather than surveying a large number of metadata schemes, Miller covers only three of the schemes most commonly used in general digital resource description, namely, Dublin Core, MODS, and VRA. By limiting himself, Miller is able to address the chosen schemes in greater depth. He is also able to include numerous practical examples that clarify common application issues and challenges. He provides practical guidance on applying each of the Dublin Core elements, taking special care to clarify those most commonly misunderstood. The book includes a step-by-step guide on how to design and document a metadata scheme for local institutional needs and for specific digital collection projects. The text also serves well as an introduction to broader metadata topics, including XML encoding, mapping between different schemes, metadata interoperability and record sharing, OAI harvesting, and the emerging environment of Linked Data and the Semantic Web, explaining their relevance to current practitioners and students. Each chapter offers a set of exercises, with suggestions for instructors. A companion website includes additional practical and reference resources.

Abstract

Improvements in network bandwidth along with dramatic drops in digital storage and processing costs have resulted in the explosive growth of multimedia (combinations of text, image, audio, and video) resources on the Internet and in digital repositories. A suite of computer technologies delivering speech, image, and natural language understanding can automatically derive descriptive metadata for such resources. Difficulties for end users ensue, however, with the tremendous volume and varying quality of automated metadata for multimedia information systems. This lecture surveys automatic metadata creation methods for dealing with multimedia information resources, using broadcast news, documentaries, and oral histories as examples. Strategies for improving the utility of such metadata are discussed, including computationally intensive approaches, leveraging multimodal redundancy, folding in context, and leaving precision-recall tradeoffs under user control. Interfaces building from automatically generated metadata are presented, illustrating the use of video surrogates in multimedia information systems. Traditional information retrieval evaluation is discussed through the annual National Institute of Standards and Technology TRECVID forum, with experiments on exploratory search extending the discussion beyond fact-finding to broader, longer term search activities of learning, analysis, synthesis, and discovery.

Rez. in: JASIST. 58(2007) no.6., S.909-910 (A.D. Petrou): "A division in metadata definitions for physical objects vs. those for digital resources offered in Chapter 1 is punctuated by the use of broader, more inclusive metadata definitions, such as data about data as well as with the inclusion of more specific metadata definitions intended for networked resources. Intertwined with the book's subject matter, which is to "distinguish traditional cataloguing from metadata activity" (5), the authors' chosen metadata definition is also detailed on page 5 as follows: Thus while granting the validity of the inclusive definition, we concentrate primarily on metadata as it is most commonly thought of both inside and outside of the library community, as "structured information used to find, access, use and manage information resources primarily in a digital environment." (International Encyclopedia of Information and Library Science, 2003) Metadata principles discussed by the authors include modularity, extensibility, refinement and multilingualism. The latter set is followed by seven misconceptions about metadata. Two types of metadata discussed are automatically generated indexes and manually created records. In terms of categories of metadata, the authors present three sets of them as follows: descriptive, structural, and administrative metadata. Chapter 2 focuses on metadata for communities of practice, and is a prelude to content in Chapter 3 where metadata applications, use, and development are presented from the perspective of libraries. Chapter 2 discusses the emergence and impact of metadata on organization and access of online resources from the perspective of communities for which such standards exist and for the need for mapping one standard to another. Discussion focuses on metalanguages, such as Standard Generalized Markup Language (SGML) and eXtensible Markup Language (XML), "capable of embedding descriptive elements within the document markup itself' (25). This discussion falls under syntactic interoperability. For semantic interoperability, HTML and other mark-up languages, such as Text Encoding Initiative (TEI) and Computer Interchange of Museum Information (CIMI), are covered. For structural interoperability, Dublin Core's 15 metadata elements are grouped into three areas: content (title, subject, description, type, source, relation, and coverage), intellectual property (creator, publisher, contributor and rights), and instantiation (date, format, identifier, and language) for discussion.
Other selected specialized metadata element sets or schemas, such as Government Information Locator Service (GILS), are presented. Attention is brought to the different sets of elements and the need for linking up these elements across metadata schemes from a semantic point of view. It is no surprise, then, that after the presentation of additional specialized sets of metadata from the educational community and the arts sector, attention is turned to the discussion of Crosswalks between metadata element sets or the mapping of one metadata standard to another. Finally, the five appendices detailing elements found in Dublin Core, GILS, ARIADNE versions 3 and 3. 1, and Categories for the Description of Works of Art are an excellent addition to this chapter's focus on metadata and communities of practice. Chapters 3-6 provide an up-to-date account of the use of metadata standards in Libraries from the point of view of a community of practice. Some of the content standards included in these four chapters are AACR2, Dewey Decimal Classification (DDC), and Library of Congress Subject Classification. In addition, uses of MARC along with planned implementations of the archival community's encoding scheme, EAD, are covered in detail. In a way, content in these chapters can be considered as a refresher course on the history, current state, importance, and usefulness of the above-mentioned standards in Libraries. Application of the standards is offered for various types of materials, such as monographic materials, continuing resources, and integrating library metadata into local catalogs and databases. A review of current digital library projects takes place in Chapter 7. While details about these projects tend to become out of date fast, the sections on issues and problems encountered in digital projects and successes and failures deserve any reader's close inspection. A suggested model is important enough to merit a specific mention below, in a short list format, as it encapsulates lessons learned from issues, problems, successes, and failures in digital projects. Before detailing the model, however, the various projects included in Chapter 7 should be mentioned. The projects are: Colorado Digitization Project, Cooperative Online Resource Catalog (an Office of Research project by OCLC, Inc.), California Digital Library, JSTOR, LC's National Digital Library Program and VARIATIONS.
Chapter 8 discusses issues of archiving and preserving digital materials. The chapter reiterates, "What is the point of all of this if the resources identified and catalogued are not preserved?" (Gorman, 2003, p. 16). Discussion about preservation and related issues is organized in five sections that successively ask why, what, who, how, and how much of the plethora of digital materials should be archived and preserved. These are not easy questions because of media instability and technological obsolescence. Stakeholders in communities with diverse interests compete in terms of which community or representative of a community has an authoritative say in what and how much get archived and preserved. In discussing the above-mentioned questions, the authors once again provide valuable information and lessons from a number of initiatives in Europe, Australia, and from other global initiatives. The Draft Charter on the Preservation of the Digital Heritage and the Guidelines for the Preservation of Digital Heritage, both published by UNESCO, are discussed and some of the preservation principles from the Guidelines are listed. The existing diversity in administrative arrangements for these new projects and resources notwithstanding, the impact on content produced for online reserves through work done in digital projects and from the use of metadata and the impact on levels of reference services and the ensuing need for different models to train users and staff is undeniable. In terms of education and training, formal coursework, continuing education, and informal and on-the-job training are just some of the available options. The intensity in resources required for cataloguing digital materials, the questions over the quality of digital resources, and the threat of the new digital environment to the survival of the traditional library are all issues quoted by critics and others, however, who are concerned about a balance for planning and resources allocated for traditional or print-based resources and newer digital resources. A number of questions are asked as part of the book's conclusions in Chapter 10. Of these questions, one that touches on all of the rest and upon much of the book's content is the question: What does the future hold for metadata in libraries? Metadata standards are alive and well in many communities of practice, as Chapters 2-6 have demonstrated. The usefulness of metadata continues to be high and innovation in various elements should keep information professionals engaged for decades to come. There is no doubt that metadata have had a tremendous impact in how we organize information for access and in terms of who, how, when, and where contact is made with library services and collections online. Planning and commitment to a diversity of metadata to serve the plethora of needs in communities of practice are paramount for the continued success of many digital projects and for online preservation of our digital heritage."

Abstract

This highly practical handbook teaches you how to unlock the value of your existing metadata through cleaning, reconciliation, enrichment and linking and how to streamline the process of new metadata creation. Libraries, archives and museums are facing up to the challenge of providing access to fast growing collections whilst managing cuts to budgets. Key to this is the creation, linking and publishing of good quality metadata as Linked Data that will allow their collections to be discovered, accessed and disseminated in a sustainable manner. This highly practical handbook teaches you how to unlock the value of your existing metadata through cleaning, reconciliation, enrichment and linking and how to streamline the process of new metadata creation. Metadata experts Seth van Hooland and Ruben Verborgh introduce the key concepts of metadata standards and Linked Data and how they can be practically applied to existing metadata, giving readers the tools and understanding to achieve maximum results with limited resources. Readers will learn how to critically assess and use (semi-)automated methods of managing metadata through hands-on exercises within the book and on the accompanying website. Each chapter is built around a case study from institutions around the world, demonstrating how freely available tools are being successfully used in different metadata contexts. This handbook delivers the necessary conceptual and practical understanding to empower practitioners to make the right decisions when making their organisations resources accessible on the Web. Key topics include, the value of metadata; metadata creation - architecture, data models and standards; metadata cleaning; metadata reconciliation; metadata enrichment through Linked Data and named-entity recognition; importing and exporting metadata; ensuring a sustainable publishing model. This will be an invaluable guide for metadata practitioners and researchers within all cultural heritage contexts, from library cataloguers and archivists to museum curatorial staff. It will also be of interest to students and academics within information science and digital humanities fields. IT managers with responsibility for information systems, as well as strategy heads and budget holders, at cultural heritage organisations, will find this a valuable decision-making aid.

Rez. in: KO 33(2006) no.1, S.58-60 (S.J. Miller): "Metadata: A Cataloger's Primer is a welcome addition to the field of introductory books about metadata intended for librarians and students. The book consists of a collection of papers co-published simultaneously as Cataloging and Classification Quarterly, Volume 40, Numbers 3/4 2005. In the Introduction, the book's editor, Richard P Smiraglia, states that "The purpose of this volume is to provide a learning resource about metadata for catalog librarians and students ... The point of the volume, overall, is that in library and information science there is an ongoing convergence of cataloging and metadata, such that the community will benefit from instructional material that demonstrates this convergence" (p. 1). The collection is divided into two major sections. Part I, "Intellectual Foundations," includes papers with an introductory and theoretical focus, while Part II, "How to Create, Apply, and Use Metadata," contains material with a relatively more practical, instructive focus. In "Understanding Metadata and Metadata Schemes," Jane Greenberg defines metadata and its functions and provides a useful framework for analyzing and comparing diverse metadata schemes based on their objectives and principles, domains, and architectural layout. In her paper "Metadata and Bibliographic Control: Soul-mates or Two Solitudes?" Lynne Howarth directly addresses the central theme of this collection by examining the historical development of, and growing convergence between, the two fields, and concludes that they are more soulmates than solitudes. In "Metadata, Metaphor, and Metonymy," D. Grant Campbell outlines the development of metadata among different stakeholder communities and employs structuralist literary theory to illuminate a perspective on metadata and information representation as special uses of human language in the form of metaphor and metonymy. Part I continues with three papers that present the results of original applied research. Leatrice Ferraioli explores the ways in which individual workers use their own personal metadata for organizing documents in the workplace in "An Exploratory Study of Metadata Creation in a Health Care Agency." In her paper "The Defining Element-A Discussion of the Creator Element within Metadata Schemas," Jennifer Cwiok analyses divergent uses of the "Creator" or equivalent elements in seven different metadata schemes and compares those with the AACR2 approach to representing authorship and intellectual responsibility. The relevance of the bibliographic concept of "the work" to metadata creation for museum artifacts is the focus of "Content Metadata-An Analysis of Etruscan Artifacts in a Museum of Archeology" by Richard P Smiraglia.
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:
- Caplan, Priscilla. 2003. Metadata fundamentals for all librarians. Chicago: ALA Editions. - Gorman, G.E. and Daniel G. Dorner, eds. 2004. Metadata applications and management. International yearbook of library and information management 2003/2004. Lanham, Md.: Scarecrow Press. - Intner, Sheila S., Susan S. Lazinger and Jean Weihs. 2006. Metadata and its impact on libraries. Westport, Conn.: Libraries Unlimited. - Haynes, David. 2004. Metadata for information management and retrieval. London: Facet. - Hillmann, Diane I. and Elaine L. Westbrooks, eds. 2004. Metadata in practice. Chicago: American Library Association. Metadata: A Cataloger's Primer compares favorably with these texts, and like them has its own special focus and contribution to make to the introductorylevel literature on metadata. Although the focus, purpose, and nature of the contents are different, this volume bears a similarity to the Hillmann and Westbrooks text insofar as it consists of a collection of papers written by various authors tied together by a general, common theme. In conclusion, this volume makes a significant contribution to the handful of books that attempt to present introductory level information about metadata to catalog librarians and students. Although it does not serve fully satisfactorily as a stand-alone textbook for an LIS course nor as a single unified and comprehensive introduction for catalogers, it, like the others mentioned above, could serve as an excellent supplementary LIS course text, and it is highly worthwhile reading for working catalogers who want to learn more about metadata, as well as librarians and instructors already well-versed in metadata topics."

Abstract

Cultural heritage professionals have high levels of training in metadata. However, the institutions in which they practice often depend on support staff, volunteers, and students in order to function. With limited time and funding for training in metadata creation for digital collections, there are often many questions about metadata without a reliable, direct source for answers. The Metadata Manual provides such a resource, answering basic questions that may appear, and explores metadata from a beginner's perspective. This title covers metadata basics, XML basics, Dublin Core, VRA Core, and CDWA schemes and provides exercise in the creation of metadata

Abstract

This book shows you how to harness the power of linked data and web-scale discovery systems to manage and link widely varied content across your library collection. Libraries are increasingly using web-scale discovery systems to help clients find a wide assortment of library materials, including books, journal articles, special collections, archival collections, videos, music and open access collections. Depending on the library material catalogued, the discovery system might need to negotiate different metadata standards, such as AACR, RDA, RAD, FOAF, VRA Core, METS, MODS, RDF and more. In Managing Metadata in Web-Scale Discovery Systems, editor Louise Spiteri and a range of international experts show you how to: * maximize the effectiveness of web-scale discovery systems * provide a smooth and seamless discovery experience to your users * help users conduct searches that yield relevant results * manage the sheer volume of items to which you can provide access, so your users can actually find what they need * maintain shared records that reflect the needs, languages, and identities of culturally and ethnically varied communities * manage metadata both within, across, and outside, library discovery tools by converting your library metadata to linked open data that all systems can access * manage user generated metadata from external services such as Goodreads and LibraryThing * mine user generated metadata to better serve your users in areas such as collection development or readers' advisory. The book will be essential reading for cataloguers, technical services and systems librarians and library and information science students studying modules on metadata, cataloguing, systems design, data management, and digital libraries. The book will also be of interest to those managing metadata in archives, museums and other cultural heritage institutions.

Abstract

Social tagging, hashtags, and geotags are used across a variety of platforms (Twitter, Facebook, Tumblr, WordPress, Instagram) in different countries and cultures. This book, representing researchers and practitioners across different information professions, explores how social tags can link content across a variety of environments. Most studies of social tagging have tended to focus on applications like library catalogs, blogs, and social bookmarking sites. This book, in setting out a theoretical background and the use of a series of case studies, explores the role of hashtags as a form of linked data?without the complex implementation of RDF and other Semantic Web technologies.

Abstract

This book offers a comprehensive guide to the world of metadata, from its origins in the ancient cities of the Middle East, to the Semantic Web of today. The author takes us on a journey through the centuries-old history of metadata up to the modern world of crowdsourcing and Google, showing how metadata works and what it is made of. The author explores how it has been used ideologically and how it can never be objective. He argues how central it is to human cultures and the way they develop. Metadata: Shaping Knowledge from Antiquity to the Semantic Web is for all readers with an interest in how we humans organize our knowledge and why this is important. It is suitable for those new to the subject as well as those know its basics. It also makes an excellent introduction for students of information science and librarianship.

Abstract

Metadata research has emerged as a discipline cross-cutting many domains, focused on the provision of distributed descriptions (often called annotations) to Web resources or applications. Such associated descriptions are supposed to serve as a foundation for advanced services in many application areas, including search and location, personalization, federation of repositories and automated delivery of information. Indeed, the Semantic Web is in itself a concrete technological framework for ontology-based metadata. For example, Web-based social networking requires metadata describing people and their interrelations, and large databases with biological information use complex and detailed metadata schemas for more precise and informed search strategies. There is a wide diversity in the languages and idioms used for providing meta-descriptions, from simple structured text in metadata schemas to formal annotations using ontologies, and the technologies for storing, sharing and exploiting meta-descriptions are also diverse and evolve rapidly. In addition, there is a proliferation of schemas and standards related to metadata, resulting in a complex and moving technological landscape - hence, the need for specialized knowledge and skills in this area. The Handbook of Metadata, Semantics and Ontologies is intended as an authoritative reference for students, practitioners and researchers, serving as a roadmap for the variety of metadata schemas and ontologies available in a number of key domain areas, including culture, biology, education, healthcare, engineering and library science.
