Foreword – Archaeometry special issue on chronological modeling

It is well understood that archaeologists, by definition, always strive to assess time as precisely as possible. However, the lack of efficient temporal data interoperability limits our understanding of cross-cultural historical evolution. This Special Issue of Archaeometry on chronological modelling features nine contributions which, while not covering all existing methods, provide a useful snapshot of current research on formalisms, methods, and standards. We hope it will help spark a ‘temporal turn’ in archaeology, much like GIS initiated a ‘spatial turn’ in the field more than 30 years ago.
