This paper discusses some key issues for digital archives and metadata in a networked information environment to keep our community memory for the future. The paper is based primarily on the experiences and lessons learnt by the author from his research activities on metadata and digital archives. The author participated in a study group on digital archives hosted by the Ministry of Internal Affairs and Communications of the Japanese Government from February 2011 to March 2012. The group discussed the promotion of digital archives in Japan, particularly at memory institutions. The Great East Japan Earthquake of 11 March 2011 caused serious damage in the north-eastern part of Japan, especially the Pacific coastal regions. This disaster significantly affected the discussions of the group. The basic lesson that the author learned is that digital archives built on a robust information environment are essential for keeping our community memory safe for the future. Not only do the primary digital resources need to be properly maintained and preserved for the future but also secondary resources, metadata and meta-metadata. We need to use Linked Open Data technologies to enhance the usability of such digital resources in the archives. 相似文献

The World Wide Web and other information technologies have deeply changed our information environment and influenced how we index and access the information we need. The library is a good example of this revolution. Instead of a building that holds books, the library is evolving into an electronic portal to digital materials from across the globe. Facing so many distributed and heterogeneous digital resources, layered metadata are efficient but sophisticated tools that make it easier to find the best information resources. In recent years many types of item-level metadata with which people are familiar have appeared. In contrast to item-level metadata, collection level metadata has not been broadly used, especially in China. By illustrating what a collection is and why we should create collection level metadata, we introduce the research and usage of collection level metadata in China and analyze the problems and limitations of the metadata being used. Some suggestions as to its use are also mentioned. 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

IndonesiaDLN — The Indonesian Digital Library Network — is a distributed collection of digital library networks, digital library servers, full local contents, metadata, and people, all engaged in developing Indonesia as a knowledge-based society. Besides the general issues of digital libraries such as publishing, quality control, authentication, networking, and information retrieval, Indonesia also faces other issues — namely, the digital divide — in designing and implementing the Indonesian DLN Network. This paper describes the basic design of the Network that enables it to handle the typical problems encountered in a developing country's digital library network, such as internet accessibility, bandwidth capacity, and network delays. Also described are the experiences in implementing the Network, which currently has 14 successfully connected partners and more than 15 partners in the process of developing their digital library servers. 相似文献

AbstractThis paper talks about Desa Informasi (Information Village), an initiative to document local information resources at Petra Christian University through the implementation of an institutional repository (IR) system. The author argues that IRs have potential and an important role in the effort to preserve and disseminate indigenous knowledge. The author also describes the relationship between institutional repositories and digital libraries, that both are interchangeable terms. The paper also describes the impacts of the project to the campus community and the society, and how projects such as Desa Informasi are important especially for developing countries. 相似文献

This special issue introductory article investigates contemporary notions of theory in journalism studies. Many scholars have argued that we need better ways of conceptualising what journalism is and how it develops in a digital age. There is, however, a lack of knowledge regarding what the theoretical trends within the interdisciplinary domain of journalism studies are today and to what extent contemporary inquiries into journalism are framed by emerging theories and perspectives. To fill this knowledge gap, we have conducted an analysis of more than 9000 metadata keywords and 195 abstracts found in the first 14 volumes (2000–2013) of the two most internationally acknowledged journals dedicated to journalism studies: Journalism—Theory, Practice and Criticism and Journalism Studies. The findings indicate that there has been a move towards greater theoretical awareness in journalism studies since 2000 and that the variety of theoretical approaches has increased. 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
