In 2006, Stanford Libraries built the Stanford Digital Repository (SDR). The system has served us well—thirteen years later, SDR contains over 2.0 million objects (~500 terabytes of content). We built SDR using open-source software (including Samvera, Fedora, and Blacklight) and an additional ~300,000 lines of custom code. We believe it is among the largest and most complex repository systems in research libraries, and yet the challenges we face are common. We have grown SDR to a point where it is extremely difficult for us to sustain. Some of our foundational technologies are not only aging but are beyond end-of-life. Meanwhile, we are challenged to continue offering a valuable, performant, highly-available repository service to our stakeholders. Over the past two years, we have analyzed the factors complicating sustainability, that work has led to operational changes that improve the current state and a plan for sustaining repository development combining open-source and custom software. Our presentation highlights the reasons SDR became unsustainable and shares areas where we have made improvements and where we go next. We believe the lessons we have learned are widely applicable to institutions that develop their own repository solutions., and A presentation at Samvera Connect 2019 described thus

Community and Sustainability", described thus, A presentation at Samvera Connect 2019, originally titled "Avalon Media System, and Over the last two years, the Avalon Media System team at the libraries of Indiana University and Northwestern University has worked toward developing a model of sustainability for a large open source project as part of a grant funded by the Institute of Museum and Library Services (IMLS). As the grant comes to a close, the Avalon team will review the efforts undertaken over the course of the two-year cycle, discussing the challenges faced by the Avalon team, as well as points of success. The Avalon team will reflect upon the experience and how opportunities provided by the grant to take on new technical changes to the system, develop code in partnership, work toward better integration with the the larger Samvera community, and develop a smaller, focused community of Avalon users and stakeholders all pointed us toward how Avalon will proceed in the years going forward. The presentation will focus on our path forward focusing on Avalon on Hyrax, new features in recent releases, additional new features being developed on the current code base, and the challenges of aligning complex projects.
