UC Curation Center: Curation Wiki

UC3 is a creative partnership bringing together the expertise and resources of the University of California. Together we provide high quality and cost-effective solutions that enable campus constituencies — museums, libraries, archives, academic departments, research units, and individual researchers — to have direct control over the management, curation, and preservation of the information resources underpinning their scholarly activities.

For more information about UC3 and our services, see our website. For specifications, documentation and technical information, see below, and please contact us with any questions: uc3@ucop.edu.

Our Infrastructure: Micro-Services

UC3 services and infrastructure -- including Merritt and EZID -- are based on a design paradigm known as "micro-services," in which a comprehensive body of preservation functions are devolved into a granular set of small, independent, but highly interoperable services.
