I am using OJS3 and i want to embed machine-readable CC licensing information in article level metadata (Please see picture) .
how i can edit metadata for all back issue articles and how add cc license.
Check if the field Licence is empty in Settings > Distribution > Permissions.
Then you might want to try the Reset Article Permissions button.
And apparently there’s no license field in the submission metadata in OJS 3?
BTW: for context, this is required for DOAJ’s Seal.
Thank you fgnievinski it solved
