DataCite Connections: A Case Study on FAIR Island Project Metadata - DataCite

"Metadata forms the backbone of open scholarly infrastructure, enabling the discoverability, accessibility, and understanding of research outputs and resources. When repositories register Digital Object Identifiers (DOIs) with DataCite, they use the DataCite Metadata Schema to describe each research output or resource. The six required metadata properties ensure that each record has the essential information to facilitate citation and retrieval. 

To support interoperability across systems, the DataCite Metadata Schema also includes properties beyond the mandatory six which can be used to establish connections between works, people, and organizations—all linked using persistent identifiers. Together, these connections form the PID Graph of relationships between research outputs and resources, as well as to related people and organizations. This blog post explores how repositories can include related persistent identifiers (PIDs) in their DOI metadata and highlights the FAIR Island project as a case study, demonstrating the potential of rich, interconnected metadata. This case study will highlight the connections described above between people, organizations, and research outputs and resources."
