Digital Preservation: Ensuring Long-term access to digital objects. The course aimes to develop in participants an appreciation of the issues surrounding digital preservation within the context of digital library development and management and to develop their grasp of the core research in the area of digital curation and preservation. Participants should leave with a coherent and practical understanding of activities surrounding digital preservation and, in particular, a developed understanding of selection and appraisal, workflow modelling, metadata definition, ingest process management, and a working knowledge of the issues surrounding audit and certification of digital repositories and the techniques and practices that underlie digital curation.
