关联数据发布技术及其实现——以Drupal为例 总被引：4，自引：1，他引：3
关联数据是一种轻量级的语义网实现技术,其重要价值在于通过RDF数据模型,将网络上的非结构化数据和采用不同标准的结构化数据转换成遵循统一标准的结构化数据,以便机器理解。文章梳理了关联数据的实现方式,目前关联数据的发布模式有:静态发布、批量存储、调用时生成、事后转换(D2R),发布关联数据的工具包括:VoID词表、前端转换工具、OWL及SKOS相关工具、Web services、Web应用框架、CMS及RDFa。并详细介绍了开源CMS平台Drupal。Drupal作为一直关注语义网技术的开源CMS平台,其高度模块化的架构为实现关联数据的发布打下了良好的基础,RDF、SPARQL、SPARQL_Endpoint及其周边模块构成了一套较为成熟的关联数据发布与消费的框架,最后利用该框架实现将"中国历史纪年和公元纪年对照表"发布成关联数据。 相似文献

关联数据开放应用协议 总被引：2，自引：1，他引：1
关联数据的应用正迅速发展并涉及到商业、媒体、出版、政府等领域。在关联数据发布、消费和再创造的过程中,必然涉及参与者的利益问题,需明确不同类型和归属的数据(或数据集)的所有权、发布权、使用权、收益权等。关联数据的发展迫切需要相关的许可协议。目前关联数据用到的协议主要有CC(知识共享)家族的CCBY-SA、CC0、CC BY、CC BY-NC和ODC(开放数据共用组织)的PDDL(公共领域奉献和许可),ODbL(开放数据许可)、ODC-By(开放数据共享署名许可),以及OGL(Open Government License,开放政府许可协议)等。对开放数据相关许可协议在国内的应用提出建议。 相似文献

关联数据的消费技术及实现 总被引：1，自引：0，他引：1
从关联数据技术实现的角度看,发布和消费是构建关联数据平台和实施关联数据应用应该考虑到的两个重要方面.关联数据的消费技术涉及到数据的访问、获取、发现、查询、交换、传输、处理和利用.而消费的方式和效果取决于关联数据源所提供的消费接口.通过梳理和总结关联数据消费技术的各个方面,调研DBPedia、Freebase、VIAF等大型的关联数据集和＜sameAs.org＞、SWSE、Sindice、Swoogle、Falcons等流行的语义搜索引擎所提供的数据消费接口,总结目前关联数据消费接口的类型以及相应的使用方式,分析其适用范围、优缺点等,以期为关联数据发布方和消费方提供技术参考. 相似文献

AbstractThe Program for Cooperative Cataloging (PCC) has formal relationships with the Library of Congress (LC), Share-VDE, and Linked Data for Production Phase 2 (LD4P2) for work on Bibliographic Framework (BIBFRAME), and PCC institutions have been very active in the exploration of MARC to BIBFRAME conversion processes. This article will review the involvement of PCC in the development of BIBFRAME and examine the work of LC, Share-VDE, and LD4P2 on MARC to BIBFRAME conversion. It will conclude with a discussion of areas for further exploration by the PCC leading up to the creation of PCC conversion specifications and PCC BIBFRAME data. 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

ABSTRACTWhile some Canadian universities have a long history in the provision of data services, that was not the norm in Canada, especially in small universities and colleges. To maximize the use of data by students and researchers in academia, it was evident that increased education, resources, and tools were required to support those delivering data services on their campuses. To this end, the Data Liberation Initiative (DLI) Survival Guide was designed as a comprehensive reference tool, which complements an established regional training curriculum, whereby enabling librarians to effectively fulfill their role as a DLI Contact in their academic institutions. This case study will examine the history, current state, and recommended future direction of the Survival Guide. This article will also examine the challenges in understanding the drivers shaping academic service delivery and the ways in which the guide has evolved to remain current to the needs of the Canadian data community. 相似文献

ABSTRACT. Data curation is one way that libraries are extending traditional services to meet the changing needs of patrons. Requirements from research funders have placed increased pressure on grant recipients to create Data Management Plans and to securely store raw data. Research universities have stepped up to provide comprehensive data support services. Despite discrepancies in funding and staff, smaller institutions can similarly provide robust services by focusing on their strengths, such as interdepartmental collaboration, flexibility, and rapid turnaround time. This article details how librarians at Trinity University adapted the larger practice of curation to meet local data management needs. 相似文献

互联网的发展产生了大量的各种类型的信息,但由于传统网络数据的发布格式缺乏结构和语义,造成了网络上大多数文档和数据的孤立。关联数据作为一种新的网络数据发布方式,通过RDF(资源描述框架)构建数据模型,通过URI(统一资源标识符)命名数据实体,发布有关联的互联网信息,使用HTTP协议获取这些相互关联的信息,实现互联网信息的语义整合,实现关联数据浏览器和搜索引擎的应用,使计算机能够更加智能化地帮助人们组织和管理信息。 相似文献

Institutional repositories have positioned themselves as an essential service for many libraries. Content-enriched metadata in library records is reported as being helpful to library users in identifying and selecting information objects for their needs. The presence of this extra-enriched content helps users to decide on the relevance of the item without the need to access the full text. Through this paper, we report content enrichment of records in an Institutional Repository using Linked Open Data datasets. In particular, this is done by application of a linked dataset in an institutional repository. The design, implementation, configuration, and workflow of the application is discussed along with implications and potential future work. 相似文献
