Merritt is a curation repository for the preservation of and
access to the digital research data of the ten campus University of California system and external project collaborators.
Merritt is supported by the University of California Curation Center (UC3) at the California Digital Library (CDL).
While Merritt itself is content agnostic, accepting digital content regardless of domain, format, or structure, it is being used for management of research data, and it forms the basis for a number of domain-specific repositories, such as the ONEShare repository for earth and environmental science and the DataShare repository for life sciences.
Merritt provides persistent identifiers, storage replication, fixity audit, complete version history, REST API, a comprehensive metadata catalog for discovery, ATOM-based syndication, and curatorially-defined collections, access control rules, and data use agreements (DUAs).
Merritt content upload and download may each be curatorially-designated as public or restricted.
Merritt DOIs are provided by UC3's EZID service, which is integrated with DataCite.
All DOIs and associated metadata are automatically registered with DataCite and are harvested by Ex Libris PRIMO and Thomson Reuters Data Citation Index (DCI) for high-level discovery.
Merritt is also a member node in the DataONE network; curatorially-designated data submitted to Merritt are automatically registered with DataONE for additional replication and federated discovery through the ONEMercury search/browse interface.
