The MARC format ushered in the age of automation for libraries. However, the standard is dated. The Library of Congress began developing BIBFRAME, a linked data ontology, five years ago to supplant this aging standard. BIBFRAME isn't merely a replacement for MARC; it is the dawn of a new age of automation. Coupled with improved search engines and the open access movement, linked data can revolutionize the way all libraries do business. This article provides an overview of linked data technologies, surveys the early results of a linked data initiative, and argues for the adoption of this technology in law libraries. 相似文献

数字化技术的广泛应用和数字档案馆工程的开展,使数字档案资源的数量迅猛增长,且数字档案资源呈现出分散、多样、异构的特点,从而形成了诸多“资源孤岛”,给档案管理者的实践工作带来巨大挑战。“关联数据作为语义网的最佳实践,是一种新兴的数据关联与集成技术”[1],其发展为解决该难题提供了新契机。基于此,本文从当前档案管理工作实践出发,分析了把语义网相关技术应用于档案管理实践工作中的必要性和可行性,并探讨如何利用关联数据及相关技术实现语义网环境下数字档案资源关联与共享模式,并提出了基于关联数据的数字档案资源关联与共享框架,推动数字档案资源建设工作向知识化、智能化方向发展。 相似文献

秦健 《现代图书情报技术》2004,20(1):16-23
语义网（Semantic Web）是当前因特网的延伸，在语义网中信息被赋予清晰的定义与含义，因而计算机和人可以更好地合作。语义网的目标是要充分发挥因特网的潜力，最终使技术能够让机器支持全球化的知识交流。实现语义网的核心是对实用分类系统（ontologies）的开发和利用。实用分类系统已经远远超出图书馆学、哲学、知识表述的范畴，图书馆、信息产业、工商业都在注视语义网技术的开发和应用。研究结果表明，实用分类系统在支持电子商务的浏览和检索与知识管理配置的可互操作性方面起着关键的作用。本文针对目前语义网的发展和实用分类系统的技术，对其应用领域、主要技术和标准、研究项目、发展动向作一综述和评论，并介绍在语义网方面的几个主要研究课题。 相似文献

Based on a set of web survey data, this study examines cataloging and metadata professionals' perspectives on issues surrounding continuing education. The results show that emerging data standards such as the Semantic Web and BIBFRAME, as well as metadata and digital library-related topics, are subject areas currently central to their professional concerns, in addition to RDA, for professional development. Topics such as ontologies, social tagging, and automatic metadata generation were rarely reported. Meaningful interactions were often found to be lacking in online education. The results provide evidence of the need to expand the pool of shared expertise to meet our collective needs for continuing education in the cataloging and metadata community. 相似文献

构建语义化知识服务系统是数字图书馆在语义Web环境下的发展方向。针对目前各种语义Web技术在数字图书馆开发应用的现状和问题,本研究融合国际基于Topic的语义知识组织技术,结合国内的需求,提出了“语义主题模型”,目标为构建可实施的语义化知识系统。文章首先对以“概念化主题、主题关联、语义标签”为内涵的“语义主题化模型”概念进行定义;其次,设计基于此模型的语义化知识系统框架;再次,对相关应用进行了探讨;最后,对未来开发工作进行了规划。 相似文献

ABSTRACTOne of the big challenges facing academic libraries today is to increase the relevance of the libraries to their user communities. If the libraries can increase the visibility of their resources on the open web, it will increase the chances of the libraries to reach to their user communities via the user's first search experience. BIBFRAME and library Linked Data will enable libraries to publish their resources in a way that the Web understands, consume Linked Data to enrich their resources relevant to the libraries' user communities, and visualize networks across collections. However, one of the important steps for transitioning to BIBFRAME and library Linked Data involves crosswalks, mapping MARC fields and subfields across data models and performing necessary data reformatting to be in compliance with the specifications of the new model, which is currently BIBFRAME 2.0. This article looks into how the Library of Congress has mapped library bibliographic data from the MARC format to the BIBFRAME 2.0 model and vocabulary published and updated since April 2016, available from http://www.loc.gov/bibframe/docs/index.html based on the recently released conversion specifications and converter, developed by the Library of Congress with input from many community members. The BIBFRAME 2.0 standard and conversion tools will enable libraries to transform bibliographic data from MARC into BIBFRAME 2.0, which introduces a Linked Data model as the improved method of bibliographic control for the future, and make bibliographic information more useful within and beyond library communities. 相似文献

The reflection provoked by RDA produced the awareness that the flat format of MARC 21 records is inadequate in expressing the relationships between bibliographic entities that the FRBR model and RDA standard consider fundamental. RIMMF and BIBFRAME indicate to software developers a way to think that is consistent with RDA. In Italy, @Cult, a software house and bibliographic agency working for Casalini Libri, has taken on the charge of following and facilitating the transition: OliSuite/WeCat provides an implementation of RDA that integrates vocabularies and ontologies already present in the Web by structuring the information in linked open data. 相似文献

Libraries are looking for a better way to encode and share their data. Christensen's disruptive technologies theory provides a framework for evaluating linked data and thinking about future uses of library technology. Because of its lack of use and technical weaknesses, linked data is not yet poised to emerge as a disruptive innovation. It has the potential, however, to become disruptive and should be explored first in spin-offs that supplement library data or provide access to other electronic content. Library systems under development should focus on remaining nimble and open to unforeseen future technologies and uses. 相似文献

AbstractThe transformation of library metadata encoded in MARC to linked data will enable libraries to participate in the Semantic Web. This transformation, however, will be an iterative development dependent upon community-based decisions. The PCC, as a community-based organization, is ideally positioned to lead this transformation. As PCC guides this transition, three broad areas must be resolved: the conversion of legacy data to linked data, the use of identifiers to support controlled headings, and the transformation of current workflows to linked-data counterparts. By embracing the Web as a community, PCC can confirm its relevance in a complex web of global data. 相似文献
