English Time and space have been among the main concerns for archivists for a very long time. In other words, how to keep information accessible and understandable for the longest time and how to organize the ever-growing amount of data. Average storage media longevity is short from an archival point of view and similarly, technological progress leads to media obsolescence. Furthermore, media decay over time as well. The sheer volume of information that professionals have to handle yearly remains a current and pressing matter. DNA is one of those “words” that everyone has heard but that most have only a nebulous grasp. DNA stands for deoxyribonucleic acid; it is a biomolecule that holds the genetic information of all living beings. DNA stores and transfers the information necessary for the development and maintenance of living organisms to the next generation. As such, it possesses astounding characteristics, honed by nature’s genius for billions of years, making it appealing as a digital data storage medium. Particularly, its longevity and its remarkable information density appear to settle the above preoccupations. However, is it a viable solution in an archival system? To operate a DNA-based storage in an archival system a prerequisite would be a conformance to the Open Archival Information System (OAIS), the reference model in authority in the world of libraries, archives and museums. This implementation will also necessitate a definition of technical characteristics that will allow an effective and efficient implementation of this media to a long-term preservation system. It is essential to define the confines of this endeavor: a structural and tangible framework within which DNA technology can be transposed into. The present work aims to establish which requirements are necessary for the system to meet the OAIS compliance and which effective technological solutions to use for an optimal fulfillment of the model through study of literature and discussion with preservation practitioners and DNA applications experts. Digital archiving in DNA is definitely feasible in accordance with the reference model and existing DNA-storage protocols. However, currently used DNA technology impedes its viability: costs and latency remain particularly high preventing an immediate application to an archival system. Different methods and protocols for information writing, access, storage and reading are being investigated to optimize the use of DNA as storage medium. In time, these technological advances will allow a competitive usage of DNA as the ultimate tool for information preservation.
