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 at ucop dot uc3@ucop.edu.

 Digital curation

Digital curation is the set of policies and practices aimed at maintaining and adding value to authentic digital resources for use now and into the future.  The curation concepts underlying UC3's activities are described here.  UC3 is developing an innovative curation infrastructure in which to manage our stakeholders' digital content.  The concept of emergent micro-services that informs this infrastructure is described here.
