Abstract

A long-term archive has to be designed in such a way that it can function for decades, despite changes in technology and methods of storage. As the technology rapidly changes, we cannot assume any currently designed module of the archive to be permanent. Therefore, an architecture of the archive has to enable quite easy and safe exchange of system modules and smooth cooperation between older and newer solutions and technologies. The architecture itself should be as stable as possible. The chapter presents assumptions and some details of the architecture of the CREDO archive. Subsystems of the archive are described and currently used technologies are briefly discussed.
