政府信息资源元数据描述框架研究   总被引:3,自引:0,他引:3  
XML作为主流的元数据描述语言,可以在电子政务系统中,为政府信息资源提供统一的描述框架。框架主要由模式层、应用层、环境层三部分组成。模式层由政府信息资源元数据描述模式框架描述,基于XML的元数据描述应用框架支撑了元数据的具体应用,而XML应用框架生命周期和XML元数据技术的协同工作解决了元数据应用的可操作性和可持续性。图1。参考文献9。  相似文献

电子政务元数据的标准化   总被引:4,自引:0,他引:4  
信息是电子政务的核心,如何有效地利用信息、促进共享是电子政务应用体系框架的目标。在这种情况下,描述并有效利用政务信息的元数据就变得更加重要,成为管理和应用政务信息资源的有效手段。因此,我国迫切需要科学地建立一套规范化的电子政务元数据标准(E-GMS)。E-GMS是支持电子政务数据标准化的基础标准之一,主要用于描述政务信息资源特征,规范信息资源使用的标准。其目标是最大程度地实现各类政务资源在管理、发现和获取方法上的一致性,体现政务信息系统的整体性,为实现不同系统间的互操作、业务协同和信息共享建立良好的基础,从而提高整个政府部门的应用水平。  相似文献

元数据对政府公开信息的描述、发现和管理有着极其重要的作用。公共图书馆在政府公开信息元数据研究方面有着极大的优势和责任。文章以中国政府公开信息整合服务平台的信息资源为例,分析政府公开信息的元数据结构,并尝试提出12个元数据字段。然而,研究发现在元数据的语义、编目和维护等方面存在着一些问题。强化分类系统建设、提升技术,机器和人工相结合,加强合作与交流等措施,可以解决目前存在的问题,并深入对政府公开信息元数据的研究,加强对政府信息资源的描述和发现,进而完善公共图书馆的政府信息服务工作。  相似文献

This article surveys a sample of sources of the information about Romania available to British readers in nineteenth century British newspapers and periodicals. It traces first contacts between the Romanian lands and Britain after the union of the principalities of Wallachia and Moldavia in 1859, then after their independence from the Ottoman Empire. The article highlights an increased Romanian interest in British periodicals, which reported and reviewed Romanian literature and scholarship. The article concludes that nineteenth century British newspapers and periodicals offer a great variety and wealth of new material previously unavailable or unknown to researchers. It also states that only a portion of a large quantity of this material has been indexed and is therefore available via the bibliographic sources mentioned in the article. The author argues for the need of a new and updated British-Romanian bibliography, which can draw on new online resources offering access to thousands of new newspapers and periodical records.  相似文献

ABSTRACT

The paper looks at library approval plans for material published in Slavic, East European, and Eurasian countries from the selector's point of view. Reasons why a selector would or would not want one are examined. Success with approval plans requires monitoring receipts, as well as good and ongoing communication among the selector, the acquistions department, and the vendor. A preliminary list of vendors offering approval plans for the countries of the region appears in the appendix.  相似文献

ABSTRACT

The article examines the most important periodicals of ethnic minorities in Poland. After 1989, many ethnic groups (e.g., Germans and Romanies) were allowed to publish journals and newspapers for the first time since the end of World War II. The publications examined show the rich cultural life of the various ethnic groups as well as their current status in Poland. In addition to popular titles, some scholarly publications are also discussed.  相似文献

The author answers a reference question on bibliographic sources for the Ukrainian periodical press 1840–1850. Helpful publications include bibliographies, guides, and library catalogs. These potentially make mention of revolutionary developments in Hungary (such as the Twelve Points paragraph of the Demands of the Hungarian Nation in March 1848, the subsequent April Laws, and Hungary's declaration of independence in April 1949), and elsewhere in the Hapsburg Empire.  相似文献

ABSTRACT

In today's current political environment raising support for millage renewals, bond campaigns or even millage continuations for public libraries is affected by national politics, and a tendency towards tax aversion on principle across the country. The lessons we can learn from the governing boards of small and rural public libraries are worth raising up to a greater national consciousness. Board governance, community consciousness, and facilities management are clear and logical tools that elected boards of public libraries can use to politick for support of libraries.  相似文献

Chromebooks and the G Suite group of products, like Google Search, Gmail, and Google Docs, have rapidly expanded in American schools during the past 5 years. The impact of one-to-one Chromebook devices and the pervasive use of Google's software products in American education cannot be overstated. This article explores some of the influences of these products on research, based on the experiences of a librarian and technology coordinator at an elementary education level. The author has several suggestions for effective research with these products in mind.  相似文献

Library historians can learn a great deal from studying the gender of authorship and institutional affiliation of a scholarly journal. The focus of this study is to examine these two aspects of journal production in library history to see who is producing published research in this field. Twenty-three years of Libraries & Culture were chosen as the target volumes. The study reveals that more men than women published in library history as well as locating which institutions were represented. This type of information is usedful to the library historian engaged in the analysis of published scholarship, and more generally to scholars with an interest in patterns of literature production in fields closely related to the social and behavioral sciences.  相似文献

ABSTRACT

The history of the almanac in Croatia is reconstructed through primary research in bibliographic and archival sources. The almanac is a vehicle for knowledge communication in informal contexts, engaging both oral tradition and literary forms traceable to medieval literacy and ways of structuring knowledge. The history of the almanac in Croatia reflects the changing context of the book trade, literacy, and the evolution of language. Four main stages are identified: (1) the beginning of the annual almanac in the seventeenth century; astrological almanacs reflecting the sensibility of the Baroque period; (2) the Enlightenment's stimulation of almanac publishing in the spirit of contemporary secular reforms in agriculture and education; (3) nineteenth-and twentieth-century almanac trade, showing complex and overlapping networks for the production, distribution and appropriation of printed almanacs;(4) roughly the end of World War II, when the almanac slowly moved out of the role of a popular mass medium and into specialized niches represented by regional, diaspora, and religious almanacs.  相似文献
