Persistence Management in Digital Document Repository

Piotr Pałka , Tomasz Śliwiński , Tomasz Traczyk , Włodzimierz Ogryczak


The CREDO Digital Document Repository enables short-and long-term archiving of large volumes of digital resources, ensuring bitstream preservation and providing most of the technical means to ensure content preservation of digital resources. The goal of the paper is to describe the design and implementation an innovative component of the CREDO Repository: the Persistence Management Subsystem (PMS). This subsystem sets guidelines for the file management system on replicas placement, and data relocation. The module responsible for scheduling access to the archive provides energy efficiency by setting suboptimal schedules. The module responsible for diagnose and exchange of data carriers calculates the probabilities of failure, and the information is used by the scheduling module to select appropriate storage areas for reading or writing of data, and for marking the areas as obsolete. Finally, the power management module is responsible for starting-up the storage areas only when necessary.
