DAITSS is a digital preservation software application developed by the Florida Center for Library Automation (FCLA) with some support from the IMLS. 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.

DAITSS was written for a multi-user environment and supports consortial as well as institutional preservation repositories.

DAITSS is available for use through a GPLv3 license. This website provides access to a fully configured VM version of DAITSS that can be downloaded to run under any VM manager, along with sample SIPs (submission packages) and documentation.
