Linked Open Data (LOD) is a core Semantic Web technology that makes knowledge and information spaces of different knowledge domains manageable, reusable, shareable, exchangeable, and interoperable. The LOD approach achieves this through the provision of services for describing, indexing, organizing, and retrievingknowledge artifacts and making them available for quick consumption and publication. Thisis also alignedwith the role and objective of traditional library cataloging. Owing to this link, majorlibraries of the world are transferring their bibliographic metadata to the LOD landscape. Some developments in this direction include the replacement of Anglo-American Cataloging Rules 2nd Edition by the Resource Description and Access (RDA) and the trend towards the wideradoption of BIBFRAME 2.0. An interestingand related development in this respect arethe discussions among knowledge resources managers and library community on the possibility of enriching bibliographic metadata with socially curated or user-generated content. The popularity of Linked Open Data and its benefit to librarians and knowledge management professionals warrant a comprehensive survey of the subject. Althoughseveral reviews and survey articles on the application of Linked Data principles to cataloging have appeared in literature, a generic yet holistic review of the current state of Linked and Open Data in cataloging is missing. To fill the gap, the authors have collected recent literature (2014–18) on the current state of Linked Open Data in cataloging to identify research trends, challenges, and opportunities in this area and, in addition, to understand the potential of socially curated metadata in cataloging mainlyin the realm of the Web of Data. To the best of the authors’ knowledge, this review article is the first of its kind that holistically treats the subject of cataloging in the Linked and Open Data environment. Some of the findings of the review are: Linked and Open Data is becoming the mainstream trend in library cataloging especially in the major libraries and research projects of the world; with the emergence of Linked Open Vocabularies (LOV), the bibliographic metadata is becoming more meaningful and reusable; and, finally, enriching bibliographic metadata with user-generated content is gaining momentum.Conclusions drawn from the study include the need for a focus on the quality of catalogued knowledge and the reduction of the barriers to the publication and consumption of such knowledge, and the attention on the part of library community to the learning from the successful adoption of LOD in other application domains and contributing collaboratively to the global scale activity of cataloging.

编目中链接和开放数据的当前状态概述

链接开放数据（LOD）是一种核心语义Web技术，它使不同知识域的知识和信息空间可管理，可重用，可共享，可交换和可互操作。LOD方法通过提供用于描述，索引，组织和检索知识工件并使它们可用于快速消费和发布的服务来实现此目的。这也与传统图书馆编目的作用和目标保持一致。由于这种联系，世界主要图书馆都将其书目元数据转移到LOD领域。在这个方向上的一些发展包括用资源描述和访问（RDA）代替了《英美编目规则》第二版，以及BIBFRAME 2.0广泛采用的趋势。在这方面，有趣的和相关的发展是知识资源管理者和图书馆界之间关于利用社会策划或用户生成的内容丰富书目元数据的可能性的讨论。链接开放数据的流行及其对图书馆员和知识管理专业人员的好处，值得对这一主题进行全面的调查。尽管文献中已经出现了几篇有关将链接数据原理应用于编目的评论和调查文章，但是缺少对编目中链接和开放数据的当前状态的一般而全面的评论。为了填补空白，作者收集了有关链接开放数据现状的最新文献（2014-18），并进行了分类，以查明该领域的研究趋势，挑战和机遇，此外，了解社交策划的元数据在编目中主要是在数据网络领域的潜力。就作者所知，这篇评论文章是第一篇在链接和开放数据环境中全面处理分类主题的文章。审查的一些发现是：链接和开放数据正在成为图书馆编目的主流趋势，尤其是在世界主要图书馆和研究项目中；随着链接开放词汇表（LOV）的出现，书目元数据变得越来越有意义和可重用。最后，用用户生成的内容丰富书目元数据的势头正在增强。
