Digital preservation as communication with the future

The problem of digital preservation is one of the most challenging research problems today and is faced by different communities with different approaches. As software and hardware evolutes the problem receives growing interest by researchers and practitioners alike. Different approaches have been made to find either individual solutions for specific fields of interest or general theories applicable to a wide range of domains. With regard to the aspect that digital preservation can be seen as communication with the future, this paper comprehensively reviews and presents approaches to digital preservation. The findings from the review are then used to develop a layered communication model that identifies necessary layers of digital preservation.
