Given the years, the money, expertise and energy we’ve spent on creating and managing archaeological data archives, the relative lack of evidence of reuse is a problem. Making our data open and available doesn’t equate to reusing it, nor does making it accessible necessarily correspond to making it usable. But if we’re not reusing data, how can we justify these resources? In their reflections on large-scale online research infrastructures Holly Wright and Julian Richards (2018) have recently suggested that we need to understand how to optimize archives and their interfaces in order to maximize the use and reuse of archaeological data, and explore how archaeological archives can better respond to user needs alongside ways to document and understand both quantitative and qualitative reuse.
However, I would argue that all these kinds of issues (alongside those of citation, recognition, training, etc.) while not resolved are at least known and mostly acknowledged. The real challenges to data reuse lie elsewhere and entail a much deeper understanding and appreciation of what reuse entails: issues associated with the re-presentation and interpretation of old data, the nature and purpose of reuse, and the opportunities and risks presented by reuse. Such questions are not specific to digital data; however, digital data change the terms of engagement with their near-instant access, volume, and flexibility, and their potentially transformative effects on the practice of archaeology now and in the future.
