Abstract

Metadata generation is the act of creating or producing metadata. Generating good quality metadata in an efficient manner is essential for organizing and making accessible the growing number of rich resources available an the Web. The success of digital libraries, the sustenance of interoperability - as promoted by the Open Archives Initiative - and the evolution of Semantic Web all rely an efficient metadata generation. This article sketches a metadata generation framework that involves processes, people and tools. It also presents selected research initiatives and highlights the goals of the Metadata Generation Research Project.

Abstract

Provides an introductory overview to the subject of metadata, which considers why metadata issues are central to discussions about the evolution of library services-particularly digital library services-and why the cataloging community is, and should be, front and center in those discussions.

Abstract

In June of this year, I performed my final official duties as part of the Dublin Core Metadata Initiative management team. It is a happy irony to affix a seal on that service in this journal, as both D-Lib Magazine and the Dublin Core celebrate their tenth anniversaries. This essay is a personal reflection on some of the achievements and lessons of that decade. The OCLC-NCSA Metadata Workshop took place in March of 1995, and as we tried to understand what it meant and who would care, D-Lib magazine came into being and offered a natural venue for sharing our work. I recall a certain skepticism when Bill Arms said "We want D-Lib to be the first place people look for the latest developments in digital library research." These were the early days in the evolution of electronic publishing, and the goal was ambitious. By any measure, a decade of high-quality electronic publishing is an auspicious accomplishment, and D-Lib (and its host, CNRI) deserve congratulations for having achieved their goal. I am grateful to have been a contributor. That first DC workshop led to further workshops, a community, a variety of standards in several countries, an ISO standard, a conference series, and an international consortium. Looking back on this evolution is both satisfying and wistful. While I am pleased that the achievements are substantial, the unmet challenges also provide a rich till in which to cultivate insights on the development of digital infrastructure.

Abstract

This review is a summary of the state-of-the-art for those who have not been intimately dealing with the evolution of digital archives. At the same time this survey will be a useful resource and starting point for archivists, librarians and technicians, who are becoming involved in institutional digitization projects. It presents a brief overview of what is meant by a digital library and a digital archive, and how archival collections can be described. It expresses briefly the different approaches to collections and their descriptions and suggests that a consistent approach to descriptions at collection and item level is an important factor in initiatives which seek to provide integrated access to distributed resources, whether those resources are traditional or digital.

Abstract

This entry is a personal remembrance of the emergence and evolution of the Dublin Core Metadata Initiative from its inception in a 1994 invitational workshop to its current state as an international open standards community. It describes the context of resource description in the early days of the World Wide Web, and discusses both social and technical engineering brought to bear on its development. Notable in this development is the international character of the workshop and conference series, and the diverse spectrum of expertise from many countries that contributed to the effort. The Dublin Core began as a consensus-driven community that elaborated a set of resource description principles that served a broad spectrum of users and applications. The result has been an architecture for metadata that informs most Web-based resource description efforts. Equally important, the Dublin Core has become the leading community of expertise, practice, and discovery that continues to explore the borders between the ideal and the practical in the description of digital information assets.

Abstract

The Library of Congress (LC) has many of the same challenges as other libraries, especially large ones. LC has many different types of resources - books, journals, maps, music, manuscripts, audio, moving image, still image, artifacts, electronic - with large collections of each. Different levels of access are needed for this material: for some, collection level bibliographic description is adequate; for many, item level access is adequate; but for others, such as sound recordings, analytic, or sub unit access is highly desirable.The sizes of the LC collections are a major challenge - over 125 million non-electronic and over 3 million electronic items (and growing rapidly). And finally, electronic resources are presenting us with new issues - from metadata to preservation to storage to linking techniques. LC has tried to approach these challenges from a service perspective. Access must be successful for the end user, which mandates as much coherence and consistency in the metadata as possible and access systems that are easy to use. This paper focuses an the Library of Congress' perspective an metadata in the following three areas: (1) descriptive metadata in our current operations, (2) pathways that are developing that will support possible evolution in the future, and (3) broader metadata needs with digital material. The discussion is from a metadata element set and format point of view, not a cataloging data and cataloging rules view. Most acronyms used in this paper are expanded in an Appendix.

Abstract

Authority control is a quite recent term in the long history of cataloguing, although the underlying principle is among the very early principles of bibliographic control. Bibliographic control is a Field in transformation by the rapid expansion of the WWW, which has brought new problems to infonnation discovery and retrieval, creating new challenges and requirements in information management. In a comprehensive approach, authority control is presented as one of the most promising library activities in this respect. The evolution of work methods and standards for the sharing of authority files is reviewed, showing the imbalance in developments and practical achievements between name and subject authority, in an international perspective. The need to improve the network availability and usability of authority information assets in more effective and holistic ways is underlyned; and a new philosophy and scope is proposed for library authority work, based an the primacy of the linking function of authority data, and by expanding the finding, relating and informing functions of authority records. Some of these aspects are being addressed in several projects dealing with knowledge organization systems, notably to cope with multilingual needs and to enable semantic interoperability among different systems. Library practice itself should evolve in the same direction, thereby providing practical experience to inform new or improved principles and standards for authority work, while contributing to enhance local information services and to promote their involvement in the WWW environment.
