The Persistent Digital Archives and Library System, or PeDALS, is a research project that has two technical goals. First, to develop a curatorial rationale to support an automated, integrated workflow to process collections of digital publications and records. Second, to implement "digital stacks" using an inexpensive, storage network that can preserve the authenticity and integrity of the collections.
In addition to those technical goals, PeDALS seeks to build a community of shared practice so that the system meets the needs of a wide range of repositories that could then support the ongoing development of the system and promote best practices. To further that end, PeDALS hopes to remove barriers to adopting the technology by keeping costs as low as possible.
