In this webinar, Stephen Abrams, Patricia Cruse, John Kunze and Perry Willett from UC3 provide background on the micro-services concept and the growing community of practice that is cohering around the idea, and a technical description and demonstration of the Merritt repository and its services. The repository supports flexible, low-barrier submission via human interfaces and machine APIs; persistent identifier minting, binding, and resolution; a semantically-enabled metadata catalog; and distributed storage sub-domains to facilitate wide-scale replication. Merritt is being used by UC3 to manage the diverse digital collections of the ten campus University of California system and a number of external content partners. It provides contributors and curators with direct control over their content and access to it; facilitates content sharing and reuse; and helps meet the requirements for data sustainability increasingly being required by grant funding agencies. Merritt will soon be made available under an open source license.
