"We are evolving our metadata schema so that we can collect ROR IDs in places where we already support the collection of Funder IDs – for instance, in the funding section of the metadata for works [...] We’re aiming to release an updated schema that supports these changes in Q1 2024."

The draft specification currently suggests that the following changes will be required:

• if we have a ROR for a funder, we should include it instead of the DOI
• when sending a ROR ID, we shouldn't also send the funder name
• if we don't have a ROR but we do have a DOI, we can continue sending that as we do currently (for now)
