开放资源互操作协议OAI研究 总被引：9，自引：0，他引：9
随着数字图书馆的发展,各种资源间的互操作性也变得越来越重要,人们也一直致力于对分布式资源进行统一检索的开发。要实现这一目标,归纳起来有三种方式:代理模式,即通过检索代理对不同的目标源分别检索,然后对检索结果统一处理;联邦检索模式,即各个目标源严格遵守统一标准或协议从而实现底层的跨库检索;采集模式,即通过元数据采集协议将分布的元数据集中提供检索。本文对这三种模式进行了对比介绍,并对国际上应用越来越广泛的 OAI 元数据互操作机制及应用进行了详细介绍和讨论。 相似文献

Metadata Quality Control in Digital Repositories and Collections: Criteria,Semantics, and Mechanisms
This article evaluates practices on metadata quality control in digital repositories and collections using an online survey of cataloging and metadata professionals in the United States. The study examines (1) the perceived importance of metadata quality, (2) metadata quality evaluation criteria and issues, and (3) mechanisms for building quality assurance into the metadata creation process. The survey finds wide recognition of the essential role of metadata quality assurance. Accuracy and consistency are prioritized as the main criteria for metadata quality evaluation. Metadata semantics greatly affects consistent and accurate metadata application. Strong awareness of metadata quality correlates with the widespread adoption of various quality control mechanisms, such as staff training, manual review, metadata guidelines, and metadata generation tools. And yet, metadata guidelines are used less frequently as a quality assurance mechanism in digital collections involving multiple institutions. 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 column uses the occasion of James Matarazzo and Toby Pearlstein receiving the 2016 John Cotton Dana Award from the Special Libraries Association to reflect on their unique partnership, which has lasted decades and resulted in a wealth of research results and tools for corporate librarians. Despite the tools available to them to measure and demonstrate their value, however, special libraries continue to face closures, downsizing, and increasing pressure to do more with less. Today, special libraries are not alone in feeling this pressure, as even the academic libraries that have been so central to campus life find their place questioned. As Matarazzo and Pearlstein formed the unlikely yet lasting partnership of scholar and practitioner, perhaps academic libraries and non-academic special libraries can join forces to effectively leverage their collective experience and knowledge in demonstrating their worth to stakeholders. 相似文献

ABSTRACTThe historical clothing collections held by academic and other institutions serve as an important resource for scholars in fields ranging from fashion design to sociology. While metadata schemes have been created for individual clothing collections, no standard metadata scheme for clothing had been developed. This case study describes the creation of a linked data metadata scheme for clothing designed for the Oregon State University's College of Business Design Programs' Historical and Cultural Textile and Apparel Collection housed within the ScholarsArchive digital repository. In addition, the scheme can be used as a standard clothing metadata scheme which may be implemented by other organizations, or extended as needed. 相似文献

ABSTRACT Digital collections of full-text e-books are proliferating on the Web and provide a wealth of open content for students. To examine whether academic libraries are providing a digital gateway to these resources, ten e-book titles from open digital collections were searched in the online catalogs and Web pages of ten academic libraries serving distance learners. Only three of the digital collection e-books were available from any of the library catalogs, and none were found on library Web pages. Availability of the ten e-book titles through Google and other digital discovery tools also had mixed results. Continued projects for improved delivery of open online content are necessary. In order to fulfill their role as digital gateways for their academic communities, libraries must pursue metadata standards to support cross-searching, collaborative projects, and development of e-resource search software, which integrates with the library catalog. 相似文献

The combination of new technologies, changing librarian roles, and a generation of “digital native” students has led to an increase in noise levels in academic libraries. The authors present a review of the literature on increased noise levels in academic libraries in an attempt to identify best practices for adapting libraries to noise and to assist reference librarians who must confront disruptive patrons. They discuss such practices as zoning libraries, furniture arrangement, written policies, signage, and peer policing for noise. 相似文献

Abstract Users of geographic data may not be able to afford to purchase and implement a dataset that does not finally meet their needs. Therefore, metadata has a very important role in the information supply environment of geographic data. The development of national/local spatial data infrastructures recognizes the importance of metadata, as do the digital libraries providing spatial data. The new ISO 19115:2003 standard of metadata for geographic information is introduced briefly. In particular, geographic information can be made available as digital maps (or images) that are meant for visual use, or as datasets meant for computational use. Metadata for digital maps is closely related to the metadata elements for conventional maps and can be enhanced by providing a sample map with the data. The case of computational use of geographic data is more complex. There are several details that may appear crucial when determining the fitness of data for an intended use. Understanding the importance of the crucial factors in each use case requires professional skills from the users of metadata. 相似文献
