Quality assured image file format migration in large digital object repositories

This article gives an overview on how different components developed by the SCAPE project are intended to be used in composite file format migration workflows; it will explain how the SCAPE platform can be employed to make sure that the workflows can be used to migrate very large image collections and in which way the integration with a digital object repository is intended. Two institutional image data migration scenarios are used to describe how the composite workflows could be applied in production library environments. The first one is related to the British Newspapers 1620-1900 project at the British Library which produced around 2 million images of newspaper pages in TIFF format. The second is a large digital book collection hosted by the Austrian National Library where the book page images are stored as JPEG2000 image files.
