Abstract

Metadata is a keystone component for a broad spectrum of applications that are emerging on the Web to help stitch together content and services and make them more visible to users. The Dublin Core Metadata Initiative (DCMI) has led the development of structured metadata to support resource discovery. This international community has, over a period of 6 years and 8 workshops, brought forth: * A core standard that enhances cross-disciplinary discovery and has been translated into 25 languages to date; * A conceptual framework that supports the modular development of auxiliary metadata components; * An open consensus building process that has brought to fruition Australian, European and North American standards with promise as a global standard for resource discovery; * An open community of hundreds of practitioners and theorists who have found a common ground of principles, procedures, core semantics, and a framework to support interoperable metadata. The 8th Dublin Core Metadata Workshop capped an active year of progress that included standardization of the 15-element core foundation and approval of an initial array of Dublin Core Qualifiers. While there is important work to be done to promote stability and increased adoption of the Dublin Core, the time has come to look beyond the core elements towards a broader metadata agenda. This report describes the new mission statement of the Dublin Core Metadata Initiative (DCMI) that supports the agenda, recapitulates the important milestones of the year 2000, outlines activities of the 8th DCMI workshop in Ottawa, and summarizes the 2001 workplan.

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 Dublin Core Metadata Initiative continues to grow in participation and recognition as the predominant resource discovery metadata standard on the Internet. With its approval as ISO 15836, DC is firmly established as a foundation block of modular, interoperable metadata for distributed resources. This report summarizes developments in DCMI over the past year, including the annual conference, progress of working groups, new developments in encoding methods, and advances in documentation and dissemination. New developments in broadening the community to commercial users of metadata are discussed, and plans for an international network of national affiliates are described.

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

For those of us still struggling with basic concepts regarding metadata in this brave new world in which cataloging means much more than MARC, an article like this is welcome indeed. In this 30.000-foot overview of the metadata landscape, broad issues such as modularity, namespaces, extensibility, refinement, and multilingualism are discussed. In addition, "practicalities" like application profiles, syntax and semantics, metadata registries, and automated generation of metadata are explained. Although this piece is not exhaustive of high-level metadata issues, it is nonetheless a useful description of some of the most important issues surrounding metadata creation and use. The rapid changes in the means of information access occasioned by the emergence of the World Wide Web have spawned an upheaval in the means of describing and managing information resources. Metadata is a primary tool in this work, and an important link in the value chain of knowledge economies. Yet there is much confusion about how metadata should be integrated into information systems. How is it to be created or extended? Who will manage it? How can it be used and exchanged? Whence comes its authority? Can different metadata standards be used together in a given environment? These and related questions motivate this paper. The authors hope to make explicit the strong foundations of agreement shared by two prominent metadata Initiatives: the Dublin Core Metadata Initiative (DCMI) and the Institute for Electrical and Electronics Engineers (IEEE) Learning Object Metadata (LOM) Working Group. This agreement emerged from a joint metadata taskforce meeting in Ottawa in August, 2001. By elucidating shared principles and practicalities of metadata, we hope to raise the level of understanding among our respective (and shared) constituents, so that all stakeholders can move forward more decisively to address their respective problems. The ideas in this paper are divided into two categories. Principles are those concepts judged to be common to all domains of metadata and which might inform the design of any metadata schema or application. Practicalities are the rules of thumb, constraints, and infrastructure issues that emerge from bringing theory into practice in the form of useful and sustainable systems.
