Automatically Batch Loading Metadata from MARC into a Work-Based Metadata Model for Music

This article describes work done at Indiana University to “batch load” data from MARC bibliographic and authority records into the Work-based and FRBR-like Variations system. A series of experiments to iteratively refine our batch loading algorithm is described, along with details of how the algorithm identifies Works, creates relationships between entities, and maps a large amount of data from MARC into Variations records. The article closes with a discussion of the potential impact of this work on Variations project workflow and community FRBRization activities.     

Linked Data Metadata for Digital Clothing Collections

ABSTRACT

The historical clothing collections held by academic and other institutions serve as an important resource for scholars in fields ranging from fashion design to sociology. While metadata schemes have been created for individual clothing collections, no standard metadata scheme for clothing had been developed. This case study describes the creation of a linked data metadata scheme for clothing designed for the Oregon State University's College of Business Design Programs' Historical and Cultural Textile and Apparel Collection housed within the ScholarsArchive digital repository. In addition, the scheme can be used as a standard clothing metadata scheme which may be implemented by other organizations, or extended as needed.

Metadata Practices in Academic and Non-Academic Libraries for Digital Projects: A Survey

This article presents the results of a survey examining and comparing the metadata practices of academic and non-academic libraries regarding digital projects. It explores the types of metadata and vocabularies utilized, issues of interoperability, end-user-created metadata, and staffing for metadata planning and creation. Participants from 87 academic libraries and 40 non-academic libraries responded to the survey. The survey found that, despite their different environments, academic and non-academic libraries engage in similar metadata practices. The majority of the participating libraries have metadata librarians, who are the primary staff members responsible for all metadata activities. Academic libraries tend to use more metadata schemes, plan for metadata interoperability more frequently, and are more likely to have created new positions responsible for metadata for digital projects.

Assessing Metadata and Controlling Quality in Scholarly Ebooks

This article explores the development and automation of quality assurance procedures for locally loading electronic books (ebooks) on the Ontario Council of University Libraries’ Scholars Portal Platform. The authors conducted a two-phase study of MARC record fields indexed on the platform to detect errors and implement workflow changes to the quality control process. The authors report on this process and the costs involved and suggest that the challenges of ebook metadata are not met by MARC and a new metadata standard should be considered in the near future.     

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.

Assessment of Metadata Quality of the Swedish National Bibliography through Mapping User Awareness

This article is examining if the metadata quality of the Swedish National Bibliography could be measured through mapping the level of user awareness regarding the characteristics of the data. A qualitative meta-synthesis was carried out and results from two previous studies conducted at the National Library of Sweden were interpreted and conceptualized through an integrated analyze. The results of the meta-synthesis showed a need for an action plan for increasing user awareness to efficiently reach target groups of national bibliographic data at its fullest potential, i.e. user awareness on the usability and the quality of the metadata.
