Merritt

Provided by the University of California Curation Center (UC3), 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 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. Through use of its companion service, UC3's EZID, a new ARK is minted and used as a primary identifier for each digital object. When used as object local identifiers, DOIs are also provided by the EZID service, which in turn 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.本数据集由加州大学馆藏中心（University of California Curation Center, UC3）提供。Merritt是面向加州大学十个校区及外部项目合作方的数字研究数据，提供保存与访问服务的馆藏存储库。Merritt可提供持久标识符、存储复制、完整性校验审计、完整版本历史、REST API、用于发现检索的综合元数据目录、基于ATOM的内容分发服务，以及由馆藏馆员自定义的馆藏集合、访问控制规则与数据使用协议（DUAs）。Merritt的内容上传与下载操作，均可由馆藏馆员指定为公开或受限访问模式。通过其配套服务——加州大学馆藏中心的EZID服务，可为每个数字对象生成新的ARK（Archival Resource Key）并将其作为主标识符使用；若将ARK用作对象本地标识符，EZID服务还可提供数字对象标识符（Digital Object Identifier, DOI），该服务同时与DataCite实现集成。所有DOI及其关联元数据会自动向DataCite完成注册，并由Ex Libris PRIMO与汤森路透数据引证索引（Data Citation Index, DCI）爬取收录，以支持高层次的资源发现检索。
