Crossref, DataCite and ORCID work together to provide a foundational open infrastructure that is integral to the global research ecosystem. We offer unique, persistent identifiers (PIDs) — Crossref and DataCite DOIs for research outputs and ORCID iDs for people — alongside collecting comprehensive, open metadata that is non-proprietary, accessible, interoperable, and available across borders, disciplines, and time. As sustainable community-driven scholarly infrastructure providers ORCID, Crossref and Datacite, guarantee data provenance and machine-readability. Persistent identifiers combined with open, standardized, and machine-readable metadata enable reliable and robust connections to be made between research outputs, organizations, individuals and much more, as well as being beneficial to others who build services and tools on top of the open infrastructure we provide making content more discoverable. In his presentation, Mohamad Mostafa shares an introduction to DataCite comprehensive approach in increasing global PIDs adoption through DataCite Global Access Program (GAP).
