DAITSS is digital preservation software application developed by the Florida Center for Library Automation (FCLA). DAITSS is used by the Florida Digital Archive (FDA), a long-term preservation repository service provided by FCLA for the use of the libraries of the eleven publicly-funded universities in Florida. DAITSS provides automated support for the functions of Submission, Ingest, Archival Storage, Access, Withdrawal, and Repository Management. It is architected as a set of RESTful Web Services and micro-services but enforces strict controls to ensure the integrity and authenticity of archived content. It implements active preservation strategies based on format-specific processing including, where necessary, normalization and forward migration. It is particularly well suited for materials in text, document, image, audio and video formats.
