The RIOXX metadata application profile was developed for institutional repositories to share metadata about the scholarly resources they contain. Originally designed to meet the reporting requirements of Research Councils UK (RCUK), RIOXX has also proven to be generally useful as a standard for sharing metadata between repositories and network services such as large-scale metadata aggregators (e.g. Core).
RIOXX focuses on applying consistency to the metadata fields used for identifiers of scholarly outputs, people and organisations, research funders and project/grants, and is designed to support the consistent tracking of open-access research publications across scholarly systems.
The RIOXX metadata application profile and its documentation (this website) is maintained by Paul Walk at Antleaf.
