OpenCitations Meta is a new database for open bibliographic metadata of scholarly publications involved in the citations indexed by the OpenCitations infrastructure, adhering to Open Science principles and published under a CC0 license to promote maximum reuse. It presently incorporates bibliographic metadata for publications recorded in Crossref, DataCite and PubMed, making it the largest bibliographic metadata source using Semantic Web technologies. It assigns new globally persistent identifiers (PIDs), known as OpenCitations Meta Identifiers (OMIDs) to all bibliographic resources, enabling it both to disambiguate publications described using different external PIDS (e.g., a DOI in Crossref and a PMID in PubMed), and to handle citations involving publications lacking external PIDs. By hosting bibliographic metadata internally, OpenCitations Meta eliminates its former reliance on API calls to external resources and thus enhances performance in response to user queries. Its automated data curation, following the OpenCitations Data Model, includes deduplication, error correction, metadata enrichment and full provenance tracking, ensuring transparency and traceability of data and bolstering confidence in data integrity, a feature unparalleled in other bibliographic databases. Its commitment to Semantic Web standards ensures superior interoperability compared to other machine-readable formats, with availability via a SPARQL endpoint, REST APIs and data dumps.

翻译：OpenCitations Meta 是一个新型数据库，为开放科学基础设施OpenCitations所索引的学术出版物引文提供开放书目元数据，遵循开放科学原则并以CC0许可协议发布以促进最大程度复用。该数据库目前整合了Crossref、DataCite和PubMed中记录的出版物书目元数据，成为使用语义网技术的最大书目元数据源。其通过为所有书目资源分配名为"OpenCitations Meta标识符"的新型全局持久标识符，既能消除使用不同外部标识符描述的出版物歧义，也能处理缺乏外部标识符的出版物引文。通过内部托管书目元数据，OpenCitations Meta消除了此前依赖外部资源API调用的限制，从而提升用户查询响应性能。其遵循开放引文数据模型的自动化数据管理流程包含去重、纠错、元数据增强及完整来源追溯，确保数据透明性与可溯源性，强化了读者对数据完整性的信任——这一特性在其他书目数据库中无出其右。相较于其他机器可读格式，其对语义网标准的坚持确保了卓越的互操作性，支持通过SPARQL端点、REST API和数据转储进行访问。
