ABSTRACTThe 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. 相似文献

[目的/意义]关联数据的研究对于数据资源的描述、组织、发布、检索、利用等具有重要意义。医学相关领域拥有庞大的数据规模和发达的数据共享实践,对该领域开放关联数据集进行系统的调查研究,对关联数据集的共享、管理、应用而言有重要的参考价值。[方法/过程]从平台分布、主题、格式、链入链出关系、所用词表等维度就医学相关领域的85个开放关联数据集进行调查及统计分析;从药物知识发现、语义关联搜索、智慧医疗建设等方面研究关联数据集的实际应用问题。[结果/结论]归纳医学相关领域开放关联数据集在科学研究和实践应用中的特点,以及在推动语义网发展和支持智慧医疗等方面的欠缺之处,以期促进对语义网、关联数据网络等关联数据发展与应用相关问题的进一步思考、探索和解决。 相似文献

The authors review how access to historical aerial photograph collections has evolved in response to technological developments and addresses areas for further advancement, with a particular emphasis on developing, preserving, and sustaining online collections. The authors focus specifically on the areas of metadata, the Semantic Web and linked data, and sustainability through collaboration. The article includes brief case studies, highlighting various projects involving the aerial photography collections at the University of Minnesota. The conclusion asserts the critical role played by geographic information librarians in effectively carrying out the strategies described in the article as they relate to the long-term sustainability of digital geospatial collections. 相似文献

关联数据是语义网的一种实现方式,描述了通过可链接的URI方式来发布、分享、链接Web中各类资源的方法,通过链接网上的分布式异构数据使得不同领域的数据相互关联,自提出以来被企业、政府等各界重视应用和研究,美国国会图书馆、瑞典国家图书馆等图书馆也加入其中,并在为图书馆提供语义服务、扩展服务资源等方面提供了选择和帮助,但关联数据在图书馆的进一步应用也还面临着用户交互、数据整合、链接维护、隐私保护等方面的挑战。 相似文献

语义关联数据网中,可互操作溯源是建立语义信任的关键手段,这在国际学术研究组织中一直是热点研究问题,W3C溯源工作小组也推出了PROV模型,以解决统一的溯源信息发布和访问问题。通过从溯源粒度、溯源状态性、溯源之溯源、自动化发布、可互操作溯源与隐私等方面的分析研究,深入阐述构建语义关联数据网可互操作溯源中的规划和技术问题,提出实践准则,为后续应用实践打下基础。 相似文献

ABSTRACTThe University of South Florida Libraries house and provide access to a collection of cultural heritage and 3D digital models. In an effort to provide greater access to these collections, a linked data project has been implemented. A metadata schema for the 3D cultural heritage objects which uses linked data is an excellent way to share these collections with other repositories, thus gaining global exposure and access to these valuable resources. This article will share the process of building the 3D cultural heritage metadata model as well as an assessment of the model and recommendations for future linked data projects. 相似文献

ABSTRACT Digital collections of full-text e-books are proliferating on the Web and provide a wealth of open content for students. To examine whether academic libraries are providing a digital gateway to these resources, ten e-book titles from open digital collections were searched in the online catalogs and Web pages of ten academic libraries serving distance learners. Only three of the digital collection e-books were available from any of the library catalogs, and none were found on library Web pages. Availability of the ten e-book titles through Google and other digital discovery tools also had mixed results. Continued projects for improved delivery of open online content are necessary. In order to fulfill their role as digital gateways for their academic communities, libraries must pursue metadata standards to support cross-searching, collaborative projects, and development of e-resource search software, which integrates with the library catalog. 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
