This is considered a valid exemption as we recognise that some consortia will have agreements that pre-date the new standard and you can report this as a reason that the metadata are missing.
In this case, during initial sample registration you would report:
- geo_loc_name (or /country) = missing: data agreement-established pre-2023
- collection date = missing: data agreement-established pre-2023
Submissions can be updated at a later date to include the missing metadata.
