Ever since OpenURL linking was introduced in 2000 by Herbert van de Sompel the link resolver has played an important role in providing users with access to the online resources they have rights to. From the start, one of the criticisms of OpenURL linking has been that it is not 100% successful—sometimes the user is presented with a link to full text, but that link fails. In 2010 a new National Information Standards Organization (NISO) workgroup was created to tackle the issue of OpenURL quality. This column will discuss this NISO initiative and look in detail at the proposed “Completeness Index” that promises a means of measuring the quality of OpenURLs being submitted by various content providers. The article will also discuss how some OpenURL quality issues may be more perception than reality and how librarians can configure their links and link resolvers to overcome these negative perceptions. 相似文献

合适的链接 最佳的服务——SFX与CrossRef/DOI交互作用探讨 总被引：3，自引：1，他引：3
介绍基于OpenURL的SFX Context Sensitive Linking和基于DOI的CrossRef这两种目前主流的动态链接系统。指出SFX具有本地化、互操作性强和可定制的特点，能够针对用户对资源的可获得性给出合适的链接；CrossRef链接直接指向出版社文献信息网页，链接准确稳定，但不适合用户获取最终文献。讨论CrossRef链接存在的问题，分析SFX的特点，并在此基础上提出将SFX与CrossRef/DOI结合使用的方法，指出这将增强和完善SFX的链接功能，同时解决CrossRef/DOI合适链接的问题。 相似文献

The Improving OpenURLs Through Analytics (IOTA) initiative was formed by the National Information Standards Organization (NISO) in 2010 to continue a Mellon-funded project on OpenURL quality begun at Cornell University. IOTA's objective is to develop a scoring system for measuring the quality of OpenURL links generated by content providers at the citation level. OpenURLs have a history of failing to resolve correctly, but no method has been devised to benchmark them even a decade after the introduction of the underlying standard. The proposed system would generate scores based on specific evaluation metrics and thus rate providers' OpenURL quality. The system's analytical approach would also enable OpenURL providers to pinpoint linking problems and thus optimize OpenURL improvements. A public OpenURL analysis tool, which relies on link data contributed by OpenURL providers and libraries, is currently in use. Recently, IOTA approached the Knowledge Bases And Related Tools (KBART) initiative about a possible collaboration on a related project, which would investigate OpenURL linking not at the citation level, but the full-text level. 相似文献

Abstract It is only a few short years since the early academic research led by Herbert Van de Sompel at Ghent University in Belgium that resulted in the formulation of the OpenURL standard and the development of the SFX link server. These complementary components have revolutionized linking for libraries, putting control for linking in the hands of the librarian. This paper considers briefly the early linking initiatives, explains the purpose and structure of the OpenURL and the role of linking components-the sources, targets, and the link server, with a focus on the SFX link server. 相似文献

ABSTRACT The electronic linking of scholarly materials has increasingly become both confusing and exciting. An understanding of the basics of linking technologies such as the OpenURL and the Digital Object Identifier (DOI) allows librarians to better serve their constituencies. Vendors also continue to offer linking alternatives to those libraries unable to purchase link resolvers, and a knowledge of these alternatives permits librarians to make informed decisions about a comprehensive and integrated linking plan for their libraries' electronic resources. 相似文献
