Reproducible preservation of databases through executable specifications

Abstract

We propose a new preservation method for relational data and a corresponding tool. The method involves writing a specification that can later be executed by the tool without user interaction, transforming the input files and databases into an encapsulated package suitable for archiving. Thus, the transformation steps become reproducible, which facilitates automation by reusing the specifications and allows for an iterative process, where for each iteration the specification is extended or adjusted and then executed to check that the result is closer to fulfilling future access requirements.
