Editorial commentary

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.
