Item Open Access Realistic digital preservation in the near future: How do we get from A to Z when B already seems too far away?Langley, Somaya; Langley, Somaya [0000-0003-3537-9957]Developed as part of the Digital Preservation at Oxford and Cambridge (DPOC), also known as the Polonsky Digital Preservation Project - http://www.dpoc.ac.uk/Item Open Access A maturity and resourcing survey for building digital preservation business cases(2018-09-24) Langley, Somaya; Pretlove, Lee; Mason, Sarah; Mooney, James; Halvarsson, Edith; Kilbride, William; Langley, Somaya [0000-0003-3537-9957]This poster outlines high-level findings of the international Digital Preservation Maturity, Resourcing, Policy and Strategy survey. The survey was created and run by the Digital Preservation at Oxford and Cambridge (DPOC) project, in collaboration with the Digital Preservation Coalition (DPC) in 2018. The purpose of the survey was to collect current information about the digital preservation maturity of organizations and their full-time equivalent (FTE) staffing resources dedicated to digital preservation activities, as well as how these FTEs are arranged. This is measured alongside organizations’ current digital preservation policy and strategy landscape. The intention is to provide up-to-date information (including the raw anonymized dataset) for organizations looking to build their own business cases and advocate for digital preservation programs.Item Open Access Cambridge University Libraries Digital Preservation Policy(Cambridge University Libraries, 2018-11-22) Langley, S; Langley, Somaya [0000-0003-3537-9957]The Digital Preservation Policy (the Policy) sets out the duties and responsibilities for Cambridge University Libraries’ (CUL) stewardship of digital content. This Policy applies to the main University Library as well as affiliate and dependent libraries. The Policy provides the overarching framework for supporting the management of digital content (encompassing born-digital and digitised content).Item Open Access Published version Peer-reviewed A maturity and resourcing survey for building digital preservation business cases(2018-09-24) Langley, Somaya; Pretlove, Lee; Mason, Sarah; Mooney, James; Halvarsson, Edith; Kilbride, William; Langley, Somaya [0000-0003-3537-9957]This poster outlines high-level findings of the international Digital Preservation Maturity, Resourcing, Policy and Strategy survey.

Design/methodology/approach This paper reviews the architecture of existing systems, then discusses experimental surveys of large digital collections using existing digital preservation tools at Big Data scales. Finally, it introduces the design of a proposed new architecture to work with Big Data volumes of preserved digital resources – also based upon experience of managing a collection of 30 million digital images. Findings Modern visualisation tools enable business analyses based on file-related metadata, but most currently available systems need more of this functionality “out-of-the-box”. Scalability of preservation architecture to Big Data volumes depends upon the ability to run preservation processes in parallel, so indexes that enable effective sub-division of collections are vital. Not all processes scale easily: those that do not require complex management. Practical implications The complexities caused by scaling up to Big Data volumes can be seen as being at odds with preservation, where simplicity matters. However, the sustainability of preservation systems relates directly to their usefulness, and maintaining usefulness will increasingly depend upon being able to process digital resources at Big Data volumes. An effective balance between these conflicting situations must be struck. Originality/value Preservation systems are at a step-change as they move to Big Data scale architectures and respond to more technical research processes. This paper is a timely illustration of the state of play at this pivotal moment.
