Implementing Automatic Digital Preservation for a Mass Digitization Workflow
The Saxon State and University Library Dresden (SLUB) has built up its digital preservation system SLUBArchiv from 2012 to 2014. In January 2015, we launched the preservation workflow for digitized documents. This workflow extends the in-house mass digitization workflow, which is based on the software Kitodo.Production. In this paper, we describe the three major challenges we faced while extending our mass digitization workflow with an automatic preparation and ingest into our digital long-term preservation system and the solutions we found. These challenges have been 
(1) validating and checking not only the target file format of the scanning process but also the constraints to it, 
(2) handling updates of digital documents that have already been submitted to the digital long-term preservation system, and 
(3) checking the integrity of the archived data as a whole in a comprehensive but affordable fashion.
