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.
