Fedora is an open source digital repository system that is flexible, durable, and standards-based. It is developed and supported by a thriving community to store, preserve, and provide access to digital objects. Fedora repositories can handle both simple and complex use cases and content models. Examples of Fedora implementations include institutional repositories, research data repositories, digital archives and special collections, and manuscript collections.
