iTunes University is a free service offered by Apple iTunes to educational institutions. It serves as a platform for the management and distribution of educational, instructional, and informational resources through both audio and video podcasts. Participation in the service among colleges and universities continues to grow since its official launch in 2007 as an official offshoot of the iTunes store. While several universities in the United States and Canada have established a presence on iTunes University, the involvement of the ARL members varies. This study surveys the presence of ARL academic libraries on iTunes University and the visibility of the library on the school's iTunes University page and examines the types of resources offered by participating libraries. It also highlights model participants as examples for other institutions and considers what implications future involvement in the service may hold for academic libraries. 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

只要是涉及资源集合搜索,现代检索系统一般都忽略了资源集合元数据的问题。而要揭示资源集合层次的信息,一种可选的方法是通过获得资源集合级和文献单元级的元数据,从而深刻理解它们之间的关系。介绍一个对资源集合与文献单元元数据关系提供分类逻辑框架的开发项目。这个逻辑构架支持：元数据规范的开发者定义元数据元素;元数据创建者描述对象;系统设计者实现应用系统的开发,该系统能够充分利用资源集合级元数据所带来的好处。介绍资源集合与文献单元元数据之间存在的三类关系实例：“属性/值传递”、“值传递”和“值约束”,表明即便是对于这些简单的例子,一个精确的公式除了要符合一阶谓词逻辑之外,还需要引入模态概念。这些公式也属于近期信息检索和本体评价方面的研究成果。 相似文献

ABSTRACT A metadata application profile identifies the metadata elements used in a particular domain or application and describes how they have been customized for that use. A metadata application profile facilitates information exchange and element re-use. In practice, the development and use of metadata application profiles present a number of challenges. This paper investigates these issues by examining the definition and function of a metadata application profile, interoperability challenges, and the evolution of thinking about metadata elements, element sets, and application profiles. The authors draw on their experience in the Government of Canada to discuss these issues and suggest rections. 相似文献

This study examines the relationship between the reviewing media and classical music recording collections in libraries in order to determine if reviews are an important selection tool for these collections. As previous studies have shown that there is a correlation between the number of reviews a work receives and the number of libraries owning that work, it is hypothesized that this relationship holds true for classical music recordings. A second hypothesis is that a correlation exists between the nature of the reviews, positive or negative, a recording receives and its ownership by libraries. The number and direction of a random sample of two hundred classical recordings released in 1989 is tallied from the review index in MLA Notes, as is the number of OCLC libraries owning each item. These data suggest that there is no correlation between the number of reviews a work receives and the number of libraries owning that work, nor between the number of positive reviews a work receives and its ownership by libraries. Possible reasons for these findings are discussed, and further questions are raised. 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 study focused on how serials information for journal articles is presented based on a sampling of institutional repository platforms at a variety of institutions. Since metadata on journal articles in institutional repositories can often be incomplete and haphazard, not only due to the difficulty of entering the metadata in the first place, but due to the difficulty of adapting existing metadata schemes to represent a journal article accurately, how can libraries increase the discoverability of these individual articles from a wide variety of journals? By examining existing metadata schemes and how they are used to represent articles currently in institutional repositories, libraries can look for a way forward to better represent articles though adapting schemas, exploring possibilities for standardization of metadata for articles, and promoting good practices. 相似文献

As open access material becomes more available across the scholarly information space, a need has arisen for creation of special metadata indicating this open access status, and for that metadata to be standard through the supply chain in order to be shared and communicated most effectively among a number of players. The National Information Standards Organization has recently launched a new work item, the Open Access Metadata and Indicators working group, which will specify a standardized set of metadata elements to detail article accessibility and license permissions. By defining how to tie availability permissions to an object useful to humans and machines, the group intends to support improved communication of this information and affect better use of open access material overall. 相似文献

In the January 1994 issue of The Cornell Veterinarian editor Maurice E. White wrote, “THIS is the last issue of The Cornell Veterinarian. The Cornell Vet has a proud history, dating back to June, 1911 …” In 2013 Cornell University Library began efforts to improve the “afterlife” for The Cornell Veterinarian journal by leveraging a number of disparate initiatives and metadata sources. While attempting to build article-level linking to full text in HathiTrust (functionality currently unavailable), limitations in the metadata captured during the scanning process were uncovered. This article will include a delineation of these metadata findings with strategies (some scalable, others highly labor intensive) for gathering the necessary metadata for creating direct links to articles found in HathiTrust. 相似文献
