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

RIOXX was developed by Jisc and the UK Research and Innovation funder community to address the gap in standard repository metadata around funder identification, grant references, embargo dates, and licences — fields essential to demonstrating compliance with funder OA policies. RIOXX records are intended to be exposed over OAI-PMH alongside oai_dc. RIOXX v3.0 (2022) aligns with the OpenAIRE Guidelines and adds richer relationship modelling.
