Distributed long-term digital archives

Piotr Pałka, Tomasz Traczyk


Different methods of distributing a digital archive, from a simple dislocation of replicas, through solutions based on a cloud or blockchain technology, to the co-operation of federated archives and the use of multi-agent systems, are discussed. Analyzes were carried out in relation to requirements set for long-term archives by the OAIS reference model, resources security, potential costs for the user, real possibility of implementation, performance, and real solution volume. The realizations of archives implemented on the basis of the considered methods are also described, including CREDO – an authors’ project of the digital repository.
