I have an OJS website and I want to implement Preprints too. I want to know whether I have to create an specific issues named as Preprints in OJS or I have to create another subdomain where Open Preprints server needed to be installed. Thank you…
OJS isn’t setup to handle preprints to the extent that OPS is. You could technically create a separate issue within OJS and assign preprints to it if you wanted, but if you want to look at running a separate preprint service, you’d have to do that distinctly (likely on a different domain or subdomain, as you noted), and OPS could be a good solution to do that. You may want to have a look at the OPS documentation to get a sense of how it works and how it differs from OJS: https://docs.pkp.sfu.ca/#appops3
Thank you very much for the brief answer and clearing my doubts.
