Open-source software has always been a key resource in digital preservation efforts. The flexibility, public accessibility (allowing users to modify and/or audit it as needed) and often low-cost of open-source software make it an appealing choice for digital archivists not only for its resource efficiency, but because it can also directly increase the chance a digital collection has to survive for extended periods of time. Open-source software can provide more control over the digital preservation process, enabling users to make more specific choices in their selection of tools to better preserve their collections. Let’s explore how open-source principles guide and are reflected in digital preservation guidelines and examine the benefits and drawbacks of using open-source software in your digital preservation system. Open Principles Parallels between open-source principles and concepts that play an important role in guiding digital preservation practice are easy to identify. Providing a framework for collaboration, transparency, and community involvement in both cases increases the efficacy and veracity of their outputs. These principles align well with the goals of digital preservation, which seek to ensure the long-term availability and accessibility of digital information, by encouraging development that can be used and audited by anyone. Open-source principles emphasise transparency, meaning that the source code for the software is publicly accessible and can be scrutinised, modified, and improved by anyone. In a digital preservation context, this transparency enables organisations to have a far deeper understanding of the processes they subject their data to, more control over their digital preservation strategies, to trust their systems more, and to make necessary decisions as technology evolves. This reciprocally improves the custodian organisations understanding of their collections, empowering them to describe and treat future content even more effectively. The collaborative nature of open-source is also a natural fit for digital preservation: a community of users who share knowledge, expertise, and resources to improve and enhance tools have the capacity to maintain stable software for longer than ephemeral private vendors. Digital preservation also naturally requires multi-disciplinary efforts, not only in the development of guidelines, strategies, and tools, but also in the physical implementation, ongoing usage and maintenance of these systems and practices; frequently requiring the involvement of IT professionals, librarians, archivists, and other highly specialised stakeholders. Open-source software offers an appealing alternative to the typical approach of proprietary solutions, which often attempt to aggregate many functions into monolithic services to reduce complexity, but in turn can reduce or eliminate the control an archivist has over their collections. In some cases, this can be to the extent that the archivist cannot be reasonably said to be taking true responsibility as the incumbent custodian of their content. They have de facto ceded the decision-making process of how their collections are treated to the vendor. This is not only counter-intuitive to the principles most digital-preservation authorities espouse: assumption of accountability, custodianship, and responsibility for the preservation of their collections on the part of the archivist, it is also dangerous for the collections. The authority on how, when, and why any actions are taken on content should always fundamentally be the archivist in charge of the collections. Any bespoke processes or protected methodologies implemented by proprietary software naturally reduce the precision and quality of the custodians understanding of their own collections. Regardless of their documentation or escrow arrangements, the users will never be able to understand a proprietary solution as closely at the lowest levels as an open one. Open Software, Open Risks
