The German National Library of Science and Technology (TIB) developed a Web-based platform for audiovisual media. The audiovisual portal optimizes access to scientific videos such as computer animations and lecture and conference recordings. TIB's AV-Portal combines traditional cataloging and automatic indexing of audiovisual media. The article describes metadata standards for audiovisual media and introduces the TIB's metadata schema in comparison to other metadata standards for non-textual materials. Additionally, we give an overview of multimedia retrieval technologies used for the Portal and present the AV-Portal in detail as well as the additional value for libraries and their users. 相似文献

This article presents the results of a survey examining and comparing the metadata practices of academic and non-academic libraries regarding digital projects. It explores the types of metadata and vocabularies utilized, issues of interoperability, end-user-created metadata, and staffing for metadata planning and creation. Participants from 87 academic libraries and 40 non-academic libraries responded to the survey. The survey found that, despite their different environments, academic and non-academic libraries engage in similar metadata practices. The majority of the participating libraries have metadata librarians, who are the primary staff members responsible for all metadata activities. Academic libraries tend to use more metadata schemes, plan for metadata interoperability more frequently, and are more likely to have created new positions responsible for metadata for digital projects. 相似文献

AbstractThis article presents examples of metadata collaborations between the Swiss National Library (NL) and research institutions in the field of Swiss historiography. The NL publishes the Bibliography on Swiss History (BSH). In order to meet the demands of its research community, the NL has improved the accessibility and interoperability of the BSH database. Moreover, the BSH takes part in metadata projects such as Metagrid, a web service linking different historical databases. Other metadata collaborations with partners in the historical field such as the Law Sources Foundation (LSF) will position the BSH as an indispensable literature hub for publications on Swiss history. 相似文献

In 2011, the University of North Texas (UNT) Libraries partnered with researchers in the university's academic departments to describe and provide access to items not traditionally included in the UNT Libraries’ systems. Including more than 1,400 items apiece, the two projects are considered active datasets by their respective users. Each collection provided new challenges in harmonizing partner, metadata, and end-user requirements. This article discusses the projects, workflow for defining requirements, and final implementation in the UNT Digital Library. These collections serve as a model for integrating other research projects easily and inexpensively into a repository infrastructure. 相似文献

Visual information dominates our modern information landscape and plays a critical role in the production of knowledge. However, research in information studies has not fully considered how people engage with visual information, in the form of images, visualization software and instruments, as well as audiovisual media, at the level of visual information in practice. This gap is addressed by first outlining the methodological challenges visual information practices pose to research, then reviewing recent information practices research projects that consider visual information, and concluding by offering a methodological framework drawn from the author's dissertation research for studying visual information practices, with suggestions provided for researchers who are interested in conducting research in this area. 相似文献
