Here's an excerpt:
The Persistent Digital Archives and Library System (PeDALS) research project was funded by the Library of Congress' National Digital Information Infrastructure and Preservation Program as part of its Preserving State Government Information initiative. The project explored the development of a curatorial rationale to support an automated workflow to process collections of digital publications and records, specifically using Microsoft BizTalk Server middleware to manage the collections and rules-based processes for their ingest. PeDALS also examined the practicality of Stanford University's LOCKSS, or Lots of Copies Keeps Stuff Safe, storage networks as an effective and inexpensive method of distributed preservation. In addition to those technical goals, PeDALS worked at building a community of shared practice among its partner states in the hopes that shared software development and best practices would foster a system that could be applied to a variety of repositories.
