Title
Border crossings : reflections on a decade of metadata consensus building

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.
