Merritt

Merritt is a curatorial repository for the preservation of digitized and born-digital library collections, research publications associated with the California Digital Library's eScholarship publishing program, and electronic theses and dissertations (ETDs) stemming from 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 the aforementioned data. 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 and access control rules. Merritt content upload and download may each be curatorially-designated as public or restricted. However, as of 2025 all repository collections are restricted. Archived research publications and ETDs are made publicly available through CDL's eScholarship publishing platform. Merritt ARKs and 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. Direct integration with Ex Libris Alma is provided through the eScholarship platform for subsequent discovery of research publications and ETDs via Primo, part of the UC systemwide ILS.

Merritt 是加州大学系统十个校区及其外部项目合作者数字研究数据保存与访问的精选资料库。Merritt 由加州数字图书馆（CDL）下属的加州大学资料中心（UC3）提供支持。尽管Merritt本身对内容无特定要求，接受任何领域、格式或结构的数字内容，但其主要被用于研究数据的管理，并构成了多个特定领域资料库的基础，例如地球与环境科学领域的 ONEShare 资料库以及生命科学领域的 DataShare 资料库。Merritt 提供了持久标识符、存储复制、完整性审计、完整版本历史、REST API、用于发现的综合元数据目录、基于 ATOM 的内容聚合，以及由资料管理员定义的集合、访问控制规则和数据使用协议（DUAs）。Merritt 的内容上传和下载可以被指定为公开或受限制。Merritt 的 DOI 由 UC3 的 EZID 服务提供，该服务与 DataCite 集成。所有 DOI 及其相关元数据均自动注册至 DataCite，并被 Ex Libris PRIMO 和汤姆森路透数据引用索引（DCI）收录，以实现高级别的发现。Merritt 还作为数据ONE网络的一个成员节点，资料管理员指定的数据提交至 Merritt 后，将自动在 DataONE 进行注册，以便通过 ONEMercury 搜索/浏览界面进行额外的复制和联合发现。
