The Florida Digital Archive (FDA) is a digital preservation repository run by the Florida Center for Library Automation (FCLA) for the use of the eleven public universities of Florida. The FDA went into production in November 2005. It ingested 108,607 files (2.2 TB) in the first 6 months of operation. The FDA uses a locally developed software application called DAITSS to support the repository functions of ingest, data management and dissemination, and the preservation functions of format normalization and format migration. Functionally, DAITSS consists of a set of services. The Ingest Service performs format validation, extraction of technical metadata, creation of derivative files through normalization and/or migration, and storage preparation. Storage Maintenance assures that stored masters remain good copies on readable media. The Access Service is responsible for access control, reporting, and building Dissemination Information Packages in response to requests. Other services include Withdrawal and Repository Management. The system does not support discovery functions for end-users or real-time online access to archived materials. It can, however, be used as a preservation back-end to institutional repositories, publishing systems, digital libraries, or other user oriented applications. Following the OAIS reference model, DAITSS assumes a community of Producers who select, prepare and submit materials for preservation. In the FDA context, these are the libraries of the public universities of Florida, which have negotiated archiving agreements with the repository. To date, most submissions have been preservation masters from local digitization projects, and electronic theses and dissertations (ETDs). This presentation will give an overview of the Florida Digital Archive and the underlying DAITSS application, which is targeted for release as Open Source Software in 2006.
