CORE guidance on REF2021 Audit
Why should deposit dates be provided by aggregators and not by single institutions?
How do I ensure that my repository's deposit date matches CORE’s deposit date?
A metadata record with a full text PDF does not appear in CORE from my own repository but it has been harvested from another repository. What if the record was not deposited on time at the other repository. Will this have an impact with regards to the REF2021 compliance?
CORE harvests full text PDFs only. Does this mean that outputs with full text in other formats, e.g. word documents or text files, will not be considered as REF2021 compliant outputs?
When I log into the CORE Repository Dashboard in the “Content” tab I see a date. Is this date the deposit date that CORE has for the output?
How can I see the deposit date from my repository's REF-able outputs in CORE?
Can I have my repository's deposit dates from CORE in a CSV file?
The date that a metadata record was created may not be the same with the date that the full text record was attached to a metadata record. How does CORE know the date that the full text was attached?
