Following three years of software development, requirements refinement, and testing, we released the integration of EPrints and Archivematica as a plugin to EPrints in 2021. This paper will explain how the integration evolved, how we implemented it in parallel to a new Archivematica instance at Concordia University, and how we are currently using it to preserve the contents of our institutional research repository. We will conclude with a discussion of some possible future enhancements envisioned for the integration.
