Metadata Quality Control in Digital Repositories and Collections: Criteria,Semantics, and Mechanisms
This article evaluates practices on metadata quality control in digital repositories and collections using an online survey of cataloging and metadata professionals in the United States. The study examines (1) the perceived importance of metadata quality, (2) metadata quality evaluation criteria and issues, and (3) mechanisms for building quality assurance into the metadata creation process. The survey finds wide recognition of the essential role of metadata quality assurance. Accuracy and consistency are prioritized as the main criteria for metadata quality evaluation. Metadata semantics greatly affects consistent and accurate metadata application. Strong awareness of metadata quality correlates with the widespread adoption of various quality control mechanisms, such as staff training, manual review, metadata guidelines, and metadata generation tools. And yet, metadata guidelines are used less frequently as a quality assurance mechanism in digital collections involving multiple institutions. 相似文献

AbstractIn response to the impact of emerging technologies, this article examines the relationship between strategic planning and the assessment methodologies of cataloging and metadata services and explores (or “suggests” if appropriate) how to assess cataloging and metadata activities more effectively and relevantly. Besides literature review, the author conducted surveys for more than seventy librarians and follow-up interviews with three library administrators. The results indicate the gap between strategic planning and assessment for cataloging and metadata services, and identify the significance of impact and users’ needs in strategic planning for the assessment of cataloging and metadata services. These elements are critical in transforming the broken links in the current cataloging assessment into a purpose-driven assessment corresponding to users’ needs and evolving technologies. 相似文献

Discussions of cataloging and metadata education are popular in social media outlets, scholarly literature, conference meetings, and so on. This article, the third installment of a longitudinal study on the state of information organization (IO) education, analyzes the recent literature to identify new and continuing themes related to IO education. It provides an overview of the curricula of the 58 library and information science graduate programs in the United States and Canada accredited by the American Library Association (ALA). It examines the current conditions in 2012–2013 and compares them to data from earlier studies. It provides an overview of the types of IO courses available, program requirements, the number of schools offering IO courses, and the number of schools teaching those courses. 相似文献

The German National Library of Science and Technology (TIB) developed a Web-based platform for audiovisual media. The audiovisual portal optimizes access to scientific videos such as computer animations and lecture and conference recordings. TIB's AV-Portal combines traditional cataloging and automatic indexing of audiovisual media. The article describes metadata standards for audiovisual media and introduces the TIB's metadata schema in comparison to other metadata standards for non-textual materials. Additionally, we give an overview of multimedia retrieval technologies used for the Portal and present the AV-Portal in detail as well as the additional value for libraries and their users. 相似文献

AbstractTo determine the state of the cataloging job market, this study compares job advertisements from August 2016-August 2018 advertising for jobs with cataloging in the title, metadata in the title, and cataloging and metadata in the title. Given ongoing concerns about the impact of metadata jobs on the cataloging job market, this study asks the questions: Are cataloging jobs in fact “disappearing” and becoming metadata jobs? Are entry-level jobs disappearing, perhaps contributing to the idea that there is a lack of qualified catalogers? Is there a difference in position level between cataloging and metadata job advertisements that can account for a lack or perceived lack of available cataloging jobs? Are there more entry-level or mid/supervisory positions advertised? Are cataloging and metadata jobs really separate, or should they be considered one position called cataloging and metadata? 相似文献

Kent State University Libraries’ electronic thesis and dissertation (ETD) cataloging process features contributions by authors, by the ETDcat application, and by catalogers. Who is doing what, and how much of it is findable in the library catalog? An empirical analysis is performed featuring simple frequencies within the KentLINK catalog, articulated by the use of a newly devised rubric. The researchers sought the degree to which the ETD authors, the applications, and the catalogers can supply accurate, findable metadata. Further development of combinatory cataloging processes is suggested. The method of examining the data and the rubric are provided as a framework for other metadata analysis. 相似文献

Cataloging has seen substantial change since 2000, and the cataloging of maps, geospatial data, and other cartographic resources is no exception. The pace and scale of change, tied to the evolution of technology and cataloging/metadata standards, have been swift and broad. This paper highlights the most important changes and trends in the cataloging of cartographic resources during the first thirteen years of the twenty-first century through a review of the published literature and summarizes the state of map cataloging today. The author concludes by proposing future directions for research and practice. 相似文献

As a growing number of disciplines adopt geospatial technologies in their research, the need for access to geospatial data, in a variety of formats, has grown dramatically. For librarians to meet this demand, we also need to provide preservation, curation, metadata, and discovery services. GeoHydra, our open source toolkit and set of practices, provides these services for Stanford's libraries. We incorporate a variety of geospatial content types from raster imagery to scientific vector data to georeferenced scanned maps, and provide a data model for repositories. We demonstrate the potential of a new architecture and practice for librarianship for geospatial data using the Hydra framework. The digitization and georeferencing of historic map collections, streamlining the acquisition and cataloging of vendor-supplied data, shared cataloging of geographic resources, and citation of geospatial research data are all examples of use cases that GeoHydra serves. Our metadata creation and management strategies implement the ISO (International Standards Organization) suite of geographic standards, and a specialized metadata schema for discovery. We developed XSLT transformations, auto-generation of core elements, unique URIs for place names, and cross-institutional data sharing. With these metadata we built a novel geoportal, EarthWorks, to provide end-user discovery for geospatial data layers using GeoBlacklight technology. 相似文献

Abstract Mounting digital images of art objects on a Web site is only the first step in providing patron access to such materials. Libraries and museums have a responsibility to provide not only high-quality digital reproductions but also high-quality access from an integrated library catalog with controlled vocabulary and consistent access points. While some digital collections may have excellent internal searchability and require no more than collection level cataloging in a library's OPAC, others may demand cataloging of individual components of the collection. A particular collection's significance, its potential audience, the types of access required, as well as factors such as its size and cohesiveness need to be considered before becoming locked into a specific Web designespecially when it is that of another institution. This paper examines several online library catalogs in which records for art objects as well as historical objects and natural history specimens have been merged, with varying degrees of success, and briefly addresses a modest proposal to catalog ceramic objects at the Ohio State University Libraries. The importance of consistent subject access in a merged catalog, regardless of the thesaurus or thesauri used, is stressed. Library consortia and bibliographic utilities may offer an economically appealing alternative for libraries that cannot design and construct their own digital libraries but these external organizations often have limited capability for-or interest in-modifying the design for a particular library and even less interest in cataloging the collections. Libraries, too, must be faulted for simply listing available electronic resources, either alphabetically or in broad subject categories, on a separate portion of their Web page and failing to provide full catalog records in their catalog. Finally, it is emphasized that the current debate over the viability of MARC 21 versus other metadata standards remains largely irrelevant to the importance of continuing to cultivate a monolithic online catalog, maintaining cataloging standards, and not mindlessly developing what amounts to a separate, rudimentary catalog solely for electronic resources. 相似文献

This article details the results of a 2011 study of cataloger librarians’ changing roles and responsibilities at academic Association of Research Libraries. The study participants, cataloging department heads, report that cataloger librarian roles are expanding to include cataloging more electronic resources and local hidden collections in addition to print materials. They are also creating non-MARC metadata. The increased usage of vendor products and services is also affecting the roles of cataloger librarians at some institutions. The article explores what skills cataloger librarians will need in the future and how libraries are providing training for that future. 相似文献

The purpose of this article is to describe the reasoning, methodology, and impact behind a semi-automated cataloging process for electronic theses and dissertations, and to explain the importance of the retention and addition of cataloger-created metadata. The authors explain an automated process that is initiated by ProQuest and student (author) entered data, and through the addition of metadata by catalogers, including the subject headings, classification number, and so on. The study includes a survey of the public service librarians’ perceived usefulness of the cataloger- and ProQuest-generated metadata to describe theses and dissertations. 相似文献

AbstractThe Program for Cooperative Cataloging's 2018–21 strategic plan includes as one of its goals to “expand [the] use of linked data value vocabularies to augment, and where feasible to replace, existing metadata practices”. This paper sets out the reasons for pursuing this goal and considers some of the implications for MARC cataloging practice. 相似文献

Abstract Users of geographic data may not be able to afford to purchase and implement a dataset that does not finally meet their needs. Therefore, metadata has a very important role in the information supply environment of geographic data. The development of national/local spatial data infrastructures recognizes the importance of metadata, as do the digital libraries providing spatial data. The new ISO 19115:2003 standard of metadata for geographic information is introduced briefly. In particular, geographic information can be made available as digital maps (or images) that are meant for visual use, or as datasets meant for computational use. Metadata for digital maps is closely related to the metadata elements for conventional maps and can be enhanced by providing a sample map with the data. The case of computational use of geographic data is more complex. There are several details that may appear crucial when determining the fitness of data for an intended use. Understanding the importance of the crucial factors in each use case requires professional skills from the users of metadata. 相似文献
