The author, a professor at Simmons College in Boston, Massachusetts, discusses the use of selected archival literature to nurture an appraisal mindset, particularly within the American context. She then addresses in some detail types of appraisal case studies and the variety of ways that they may be used as teaching tools.  相似文献

Digital repositories require good metadata, created according to community-based principles that include provisions for interoperability. When metadata is of high quality, digital objects become sharable and metadata can be harvested and reused outside of the local system. A sample of U.S.-based repository administrators from the OpenDOAR initiative were surveyed to understand aspects of the quality and creation of their metadata, and how their metadata could improve. Most respondents (65%) thought their metadata was of average quality; none thought their metadata was high quality or poor quality. The discussion argues that increased strategic staffing will alleviate many perceived issues with metadata quality.  相似文献

As the University of Minnesota's Archives and Special Collections began the daunting task of migrating into ArchivesSpace over 5,000 finding aids from fifteen different units, a clearly defined workflow provided clarity and success. This article outlines how staff developed an implementation timeline and workflow, harnessed support from partners in IT, provided training, and what the benchmarks to success were. By sharing this well-documented and thought-out implementation workflow, it can provide guidance as others try to navigate the many moving parts of implementing new collection management technology.  相似文献

As the archival profession has adapted to new challenges and adopted modern practices like More Product, Less Process, the University of Minnesota has embraced these changes. Even so, implementing new practices can take time and effort. With the adoption of ArchivesSpace in 2016, the University found itself being fast-tracked to even more efficient methods for establishing physical and intellectual control over collections. This article will examine the case studies of two large collections that were in the midst of being processed when ArchivesSpace was implemented at the University of Minnesota. How did the switch to ArchivesSpace impact the processing of these collections, and how will these experiences impact the future of archival processing at the University?  相似文献

This survey of official U.S. tribal websites examined sites for documentary materials of importance to each tribe that have been archived online, including such materials as historical essays, photos, videos, maps, newspapers, legal and historical documents, historical images, books, pamphlets, bibliographies, cultural and language materials. The materials found on those websites appear to be intended for the use of both tribal members and the general public. The result of the survey was to show that many of the same types of documentary materials held in tribal archives are also available on official websites, and to produce a current snapshot of the large array of tribal records which have been made openly available, although the length of time each document will be available on each site is unknown.  相似文献

Since the turn of the century large groups of former institutionalised children have exercised their right to see their ‘personal files’, and this has drawn widespread attention to these documents and their potential in scholarly research. This article explores the meanings of personal files from the period 1945–1984 as sources for both historical researchers and adult care leavers themselves, in the context of the orphanages in Ghent, Belgium. Based on the experiences of those who have consulted their files, we come to the conclusion that the personal files of the Ghent orphans provide some new information but, at the same time, leave a lot of issues unresolved. Although the files offered significant insights for researchers studying the most recent period in the history of the Ghent orphanages, it is difficult to see them as ‘keys to the past’ for former orphans who are trying to (re)construct their own, individual life histories.  相似文献

一种入侵容忍的资料库   总被引:2,自引:0,他引:2  
ARECA的设计保护了CA私钥的保密性,使ARECA能实时在线地为用户签发证书或撤销证书;但作为安全的在线CA,分发证书的资料库的安全也是关键问题。ARECA的资料库是入侵容忍的,通过将复制的服务器组织成分发屏蔽失效法定数目团体系统,能屏蔽良性失效或者被攻击者控制的服务器的行为,为用户提供正确的证书和证书撤销列表查询服务。异步通信条件下,n>3f个服务器组成的资料库能够容忍至多f个服务器同时失效。  相似文献
