Digital chronological data reuse in archaeology: three case studies with varying purposes and perspectives

A wealth of digital data are produced during an archaeological excavation and because so much of the fieldwork is unrepeatable, once the site is fully excavated, the digital records must be archived in a manner that best facilitates reuse. This paper presents three case studies of users wishing to reuse digital archaeological data from online repositories, with a specific focus on absolute and relative dating evidence. We discuss the problems encountered and how they reflect the wider issues of the reuse of digital archaeological data. Additionally, we provide recommendations specific to chronological data that seek to address the problems.
