Answers are drawn from this dictionary entry and the rest of the CASRAI corpus, with a link to every source.

Answers are AI-generated from CASRAI’s own published pages and can be wrong, so check the linked sources before relying on one; your question is logged without personal data — never sold, never used to train a third-party model — to show us what CASRAI is missing, so please do not type personal or confidential details. How we use this

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.
