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

The meta-synthesis method has received increased interest in social science research, but relatively few meta-synthesis studies have been conducted in the library and information science (LIS) field. The purpose of this study was to analyze 44 LIS-related meta-synthesis studies in terms of contribution, meta-synthesis methodology, and research topics. The results revealed that there are four types of contributions of meta-synthesis research: isolated findings, non-dynamic relationships, dynamic relationships, and models. Moreover, a variety of methods have been used to search, select, analyze, and synthesize the individual studies. Finally, although meta-synthesis studies have been conducted on some LIS topics (e.g., health informatics, library user services, and information management), it has been an undervalued method for other research topics. Recommendations are offered to encourage the use of this method and to guide researchers to conduct more rigorous meta-synthesis studies on LIS topics. 相似文献

This article analyzes resource authors' use of a metadata creation application at the National Institute for Environmental Health Sciences (NIEHS). Users' behavior was observed as they created metadata, and feedback about the application was solicited. Data analysis focused on usability—specifically task structure, duration, user perceptions, and researcher observations. Developing a conceptual understanding of metadata and its use in retrieval was challenging for users. The study identifies particular interface elements (e.g., input fields) as well as element semantics and syntax that impact application usability and metadata creation. Implications for information architecture and interface design include the need to incorporate metadata creation into user-centered design processes and develop advanced applications that reduce the burden on authors. 相似文献

Metadata go through an evolutionary process from creation to archival preservation. During this process, some metadata are re-used (inheritance), other metadata are eliminated (extinction) and still others are updated or newly generated (mutation). Unlike other literature that focuses on metadata inheritance and mutation, this evolutionary view highlights the extinction of metadata. As such, it might raise awareness about the appraisal and selection of metadata in digital curation practice. 相似文献

This article presents a case study of quality management for print and electronic resource metadata, summarizing problems and solutions encountered by the Cataloging and Discovery Services Department in the George A. Smathers Libraries at the University of Florida. The authors discuss national, state, and local standards for cataloging, automated and manual record enhancements for data, user feedback, and statewide consortial factors. Findings show that adherence to standards, proactive cleanup of data via manual processes and automated tools, collaboration with vendors and stakeholders, and continual assessment of workflows are key to the management of biblio-graphic data quality in consortial academic libraries. 相似文献

在数据化的网络时代,用户需求与图书馆服务形式向深度专业的知识化和智慧化发展。面对这种新常态,第三代图书馆服务平台的元数据管理不仅需要解决图书馆集成管理系统甚或是"下一代"图书馆服务平台受困于MARC的现状,满足资源的统一管理与业务整合,更需要考虑统一的数据建模与编码方式,实现跨类型的数据流通和知识的组织与融合。这就为元数据管理提出了新的需求,包括:完整的生命周期管理,资源类型兼容,标准规范兼容,互联网环境下的书目与规范控制,知识组织与融合。这种运用平台化思维、改变图书馆运行生态的可能性可以在FOLIO项目中看到希望。FOLIO作为以微服务架构设计的图书馆服务平台,在设计之初就定义了一个核心的微服务域--Codex。一方面,Codex作为数据注册中心和数据链接中介位于FOLIO架构的顶层,通过Codex消除不同域中数据的编码、格式和存储位置的差异,以减少域之间的交互与耦合。另一方面,Codex以BIBFRAME 2模型为基础设计了"作品-实例-单件/馆藏"的抽象数据模型,并参考DC元素设计了一套最小核心元数据元素集。Codex记录不描述资源的详细信息,只起到揭示与定位的作用。专有的业务信息或更详细的记录信息都可以通过Codex链接到相应的记录层获取。Codex作为核心的元数据管理域,将被设计成为FOLIO平台的资源链接中心、规范数据中心、跨域的全媒体资源管理入口,并通过模型中的抽象实体揭示资源间的关系。虽然现阶段仅实现了不存储自身数据的Codex Search,对关联数据的支持也不够完善,但无论是其抽象的数据模型,还是最小化的元数据方案,以及"统一记录-业务记录-正式记录"的分层描述原则,Codex都有足够的灵活性支持面向实体对象的描述与组织。 相似文献

As the amount of research data management is growing, the use of identity metadata for discovering, linking, and citing research data is growing too. To support the awareness of different identifier systems and the comparison and selection of an identifier for a particular data management environment, there is need for a knowledge base. This article contributes to that goal and analyzes the data management and related literatures to develop a data identifier taxonomy. The taxonomy includes four categories (domain, entity types, activities, and quality dimensions). In addition, the article describes 14 identifiers referenced in the literature and analyzes them along the taxonomy. 相似文献

There is a current trend to make museum collections widely accessible by digitising cultural heritage collections for the Internet. The present study takes a user perspective and explores the characteristics of online museum visitors' web search behaviour. A combination of quantitative and qualitative methods was deployed in a case study at a National Museum of Military History. Quantitatively, data from a web questionnaire survey and a user study of interactive searching behaviour were collected and analysed. Qualitatively, observation protocols were coded and analysed based on inductive content analysis. It was found that metadata elements on factual object related information, provenience, and historic context was indicated to be relevant by the majority of the respondents, characterising the group of special interest museum visitors as information hungry. Further, four main characteristics of online museum visitors' searching behaviour were identified: (a) searching behaviour has a strong visual aspect, (b) topical searching is predominantly exploratory, (c) users apply broad known item searches, and (d) meaning making is central to the search process. 相似文献
