This paper aims to describe the Florida Digital Archive (FDA), a long‐term preservation repository for the use of the public university system of Florida, and the DAITSS preservation repository application used by the FDA. It seeks to explain requirements that shaped DAITSS design, outline functions of the current software, and describe how DAITSS is being rearchitected as a series of Web Services (DAITSS 2). It also endeavours to place the FDA and DAITSS in the context of various models for implementing digital preservation functions.


This is a case study of one model of digital preservation implementation that includes some comparison with examples of other models. The preservation protocol implemented by DAITSS combines bit‐level preservation, format normalization, and forward format migration; extensive preservation and format‐specific metadata are supported, and authenticity of content is maintained through application design and a complete record of digital provenance.


The formal OAIS model has much to offer, and DAITSS could be part of a preservation solution for large academic/research libraries and for consortia who can share central computing facilities and staff.

Practical implications

When DAITSS 2 is completed and implemented by the Florida Digital Archive, the code will be released for use under an open source license. Institutions, consortia and third party service providers looking for a more complete preservation solution than simple replication can consider using DAITSS 2 as their digital preservation repository application.


There are very few preservation repository applications that do nothing but digital preservation, do it well, and formally implement the OAIS model. The Florida Digital Archive's DAITSS was the first of its kind in the USA. DAITSS 2 will conform to the same requirements as DAITSS and will retain the same functionality, but it will be easier to implement and manage in production, and easier to maintain and enhance.
