Editorial commentary

Built from the OpenAIRE Research Graph project, the OpenAIRE Graph (also called the OpenAIRE Research Graph) ingests metadata from CrossRef, DataCite, ORCID, Microsoft Academic Graph (legacy), and from harvest-compliant repositories and CRIS systems following the OpenAIRE Guidelines. Sophisticated entity-deduplication and link-inference algorithms produce a unified graph. The graph powers OpenAIRE EXPLORE for end users, OpenAIRE PROVIDE for content provider services, and is published as bulk dumps via Zenodo.
