Data protection regulations like GDPR Privacy and Privacy Enhancing Technologies (PETs) are required to protect user rights for publishing platforms like Open Journal Systems (OJS). All stakeholders, from readers to journal managers must consent to private data collection. Consent related functions require explicit authorization for Data usage in OJS and in reviewing process. Journal consumer privacy should also be protected and respected, while ensuring that technical requirements remain intact to maintain smooth functionality. User creation and reviewer invitations must be revised and rewritten to support the requirements of the GDPR. The handling of cookies is another important area to be addressed. Institutional providers and small publishers have either neglected or used manual workflows to provide at least limited support for GDPR compliance, which may be unsustainable and less cost-effective. The weaknesses identified in the multilingual support of OJS are being thoroughly investigated and solutions are proposed and implemented. This proactive approach is geared towards ensuring smooth handling of multilingual content, enhancing interoperability and seamless synchronisation with external systems. By addressing these issues, we help journals to manage different languages efficiently and improve accessibility and usability across language boundaries. Eventhough OJS is the world's most widely used open source platform for publishing scholary and non-scholary content, there have been shortcomings and in some use-cases no built-in support for the two aspects mentioned above. In joint collaboration with PKP under European Grant CRAFT-OA, Technischerinformationsbibliothek and Federation of Finnish Learned Societies has taken the intiative to develop the above shortcomings for OJS. We are presenting the workflows, usability designs and the features developped during the project, which will be integrated to next OJS version 3.5. These commitments of european partners, underlines OJS' endeavour to meet the diverse needs of its users and promote a truly inclusive scholarly publishing environment.
