Ah I think I have a better understanding.
RIOXX is a list of key metadata fields required to report to RCUK
We can map existing fields in our systems to this (or add new fields if there are gaps).
The EPrints and DSpace plug-ins are intended for us to map to RIOXX and then export data in format suitable for RCUK reporting.
Test versions coming soon.
RIOXX also looking at reporting tools for REF in a similar fashion but a journey and consultation on this still to take place so there is time to work with Jisc and RIOXX on this. Possibly envisaging REF plugins for these systems that allows mapping of existing fields where systems can’t or don’t hold these for whatever reason, and ability to add data to the extract outwith the system if necessary.
