I am trying to get DOAJ indexing, however, they require CLOKSS or LOCKSS archieving system, I am using ojs 3.0.1 which is not supported and neither the version 3.2 is supported.
is there any alternative solution or another service to do the archiving and will be recognized by DOAJ?
DOAJ knows that OJS is automatically accepted by LOCKSS. Just let them know that you have applied for LOCKSS, they will consider this point.
We have done the same and now we are indexed in DOAJ https://jlmc.edu.np
As far as I’m aware it is needed only for the premium “seal”. It is not mandatory.
