Data seal of approval - assessment and review of the quality of operations for research data repositories

The Florida Digital Archive (FDA) is a long-term preservation repository for the use of the libraries of the public universities of Florida. The FDA uses locallydeveloped software called DAITSS, which was designed to perform the major functions of Ingest, Archival Storage, Data Management and Dissemination in the OAIS reference model. A DAITSS 2 project is in process to re-write the application based on a distributed, Web services model. This paper describes the major changes in store for DAITSS 2.0, the rationale behind them, and the issues involved in their design and implementation. These changes include: moving from a monolithic to distributed processing environment; implementation of modular RESTful services; incorporation of existing tools, services, and registries; and revising the internal data model to be more conformant with the PREMIS data.
