During the last 15 years, records managers and archivists have focused on defining requirements for functionality and metadata of electronic records management systems. So far little is known about metadata that are actually created in these systems. This study examines metadata in records of a Finnish government agency. The metadata comply with the national SÄHKE records management metadata specification. The main findings are that a substantial number of metadata elements in SÄHKE remained unused. Generated metadata were largely about event history. Optional metadata elements were used rarely. The metadata show clear patterns, which may suggest systematic recordkeeping processes and possibly minimal human intervention in metadata creation. 相似文献

Analysis of a survey of the types and extent of tools and techniques related to semi-automatic metadata generation applied in real-world library settings indicates that practical applications in libraries seem to be at an incipient stage. More than half (n = 149, 52.5%) of the survey participants (n = 285) specify that semi-automatic metadata generation has not been utilized for metadata creation and management in their libraries. This figure becomes even higher when adding the response “don't know,” constituting an additional 13.7%. The results of the survey also show that the semi-automatic metadata generation tools described by participants mostly concern metadata format conversion (38.6%) and metadata templates and forms (27%) for populating certain metadata values. Complex tools and the generation and extraction of metadata directly from the content and context of the digital objects are rarely applied in libraries. This indicates that more research is needed on the development of automatic metadata generation for semantic metadata in usable and practical settings. 相似文献

ABSTRACTDiscovery tools are used in libraries to bring together books, articles, and other resources. Research has focused on user and librarian evaluation of these tools, but there are few evaluations of non-book and non-article sources. Discovery tools can also include metadata for local collections harvested through the Open Archives Initiative Protocol for Metadata Harvesting (OAI-PMH). Creating these harvests can be time consuming for staff, so it is important for libraries to understand if and how patrons use these records. The University of Nebraska-Lincoln Libraries (UNL Libraries) harvests metadata from local collections into the Encore discovery tool. A study was conducted to analyze patron use of OAI-harvested records. This study analyzed usage data for harvested collections obtained from different discovery sources and referrals through Encore. Google Analytics was used to evaluate searcher behavior differences between content referred through Encore and other referrals. Although discovery through Encore did not result in high numbers of traffic, there is evidence that patrons who discover records through Encore take more time looking through records than patrons using other discovery methods. This increase in time is a measure of engagement and may be reason enough for libraries to consider adding OAI-harvested collections to their discovery tool. 相似文献

The Continuum concept of pluralisation is often misunderstood. This paper aims to explain how records are embedded in the society that created them from the time of their creation and how they can be further embedded throughout their lifespan by adding metadata to them, placing them in context, making them accessible to those who will need them in the future and potentially sharing them with the broader society according to societal rules. The author proposes to use the concept of societal embeddedness, which indicates that pluralisation is not just about sharing in the future, but also about incorporating societal expectations in records and recordkeeping systems, to help explain the concept of pluralisation. She shows how using simple examples from everyday life and discussing the societal context of the creation and use of records can help explain Records Continuum concepts, and in particular the concept of pluralisation, to students from non-English speaking backgrounds.

电子档案元数据是保障电子档案真实、可靠、完整、可用的手段之一,确保电子档案元数据自身的真实性是证明电子档案真实的前提。照片类电子档案部分元数据的取值源于电子照片可交换图像文件格式（EXIF）,但EXIF中的信息是容易被修改的。为此,本文采用电子照片来源检测技术对编号为M43（捕获设备）的子元数据M44（设备制造商）和M45（设备型号）的真实性进行检测,利用电子照片自身信息的关联性对编号为M54（图像参数）的子元数据M57（图像高度）和M58（图像宽度）的真实性进行检测,以此引起学界对电子档案元数据真实性研究的关注,以期为电子档案来源可靠问题的解决提供新的思路和方法。 相似文献

ABSTRACT As more archival metadata and archival records become available online, providing effective interfaces to those materials is increasingly important to give users access. This article describes five approaches from the hypertext and visualization research communities which can be used to improve such access: (1) navigating hierarchical structures, (2) illustrating networks of relationships, (3) viewing organizational processes, (4) using time and space as organizing structures, and (5) spatializing arguments and discussions. This article addresses particular challenges in applying these visualization techniques to archival records and considers novel challenges introduced by them for both archival organization and for visualization research. 相似文献

Macro-level indicators of the relations between research funding and research output 总被引：3，自引：0，他引：3
In response to the call for a science of science policy, we discuss the contribution of indicators at the macro-level of nations from a scientometric perspective. In addition to global trends such as the rise of China, one can relate percentages of world share of publications to government expenditure in academic research. The marginal costs of improving one's share are increasing over time. Countries differ considerably in terms of the efficiency of turning (financial) input into bibliometrically measurable output. Both funding schemes and disciplinary portfolios differ among countries. A price per paper can nevertheless be estimated. The percentages of GDP spent on academic research in different nations are significantly correlated to historical contingencies such as the percentage of researchers in the population. The institutional dynamics make strategic objectives such as the Lisbon objective of the EU – that is, spending 3% of GDP for R&D in 2010 – unrealistic. 相似文献

How we imagine records affects what we acquire and how we manage it. I take up the call from Arjun Appadurai to view archives as deliberate creations, and from Hugh Taylor to use imagination as a means of creative engagement with archival theory. I explore how we can reimagine archival work, mandates, and records by eschewing divisions of content and metadata, acknowledging items and aggregations to be interchangeable concepts, and integrating data about use into archival data management. 相似文献

Abstract Many libraries use RSS to syndicate information about their collections to users. A survey of 65 academic libraries revealed their most common use for RSS is to disseminate information about library holdings, such as lists of new acquisitions. Even though typical RSS feeds are ill suited to the task of carrying rich bibliographic metadata, great potential exists for developing applications that can exploit metadata exposed to Web services via RSS. Using the MODS metadata format, entire catalog records can be seamlessly embedded in RSS 2.0 feeds. Existing tools, such as Library of Congress Java toolkits and XSLT stylesheets, can facilitate this process, while a new XSLT stylesheet may be used to create the RSS feeds complete with MODS records. As an example of the added functionality these MODS/RSS feeds can offer, records from a MODS-enriched RSS feed can be ingested into a non-RSS application such as Zotero. As more emerging library technologies use Web services architectures to handle data objects, the ability to syndicate catalog records will become more critical to providing innovative library Web services. 相似文献

This article summarizes published documents on metadata provided by Google for books scanned as part of the Google Book Search (GBS) project and provides suggestions for improvement. The faulty, misleading, and confusing metadata in current Google records can pose potentially serious problems for users of GBS. Google admits that it took data, which proved to be inaccurate, from many sources and is attempting to correct errors. Some argue that metadata is not needed with keyword searching; but optical character recognition (OCR) errors, synonym control, and materials in foreign languages make reliable metadata a requirement for academic researchers. The authors recommend that users should be able to submit error reports to Google to correct faulty metadata. 相似文献

The Korean government's electronic record management reform: The promise and perils of digital democratization 总被引：1，自引：1，他引：0
Recently, the Korean government instituted a reform in its archives with the goal of increasing transparency in government and meeting the challenges of the new digital environment in records management. President Roh's administration focused on a “process and system” reform through a shift from paper-based records management to electronic records management. The E-jiwon task management system of the Office of the President, invented by President Roh himself, served as the archetype for the reform. This study explores and critiques the administration's choice of a “process and system” reform over institutional reform, examines the legal framework used to enact the reform and its shortcomings, and analyzes the benefits and deficiencies of the E-jiwon as a tool for democracy in the archives. It concludes that while the new digital environment can assist in promoting government transparency, technological change by itself is inadequate; ultimately, institutional change is necessary for true reform. 相似文献

2015年澳大利亚维多利亚州发布VERS 3 版标准,其封装策略从电子文件和元数据的一体式XML文件封装,变为元数据XML文件和电子文件内容的分体式封装,配套的元数据规范、长期保存格式标准、数字签名机制也都发生变化。本文分析了这些变化,并对电子文件元数据封装策略的定位和应用进行了思考。VERS元数据封装是一项面向电子文件长期保存的综合性策略,在借鉴应用时不宜仅视为一个单项技术,应根据需要确定采用何种电子文件元数据封装策略,并在应用过程中注重其简便性、灵活性和效率。 相似文献
