I am using OJS 3. I would like to add additional attributes (fields) to submission metadata. The point is we would like to have some additional data there. Please let me know:
What do you think about that approach (does it seem reasonable)
A while back I also wrote a custom metadata plugin for OJS3, but it lacks an UI for adding/editing the metadata fields: GitHub - ajnyga/customMetadata
I have not tested this with 3.1. but I this is probably one of the things I will work on during this year.
