OJS – Open Journal System

Open Journal System, OJS, is an open source publishing software developed by PKP that enables the publication of scientific journals. With OJS, editorial teams can manage the entire editorial flow: submission, reviewing of articles, choice of reviewers, layout… Created in 2001 by PKP, OJS is written in PHP and uses MariaDB or PostgreSGL databases. OJS can be installed on a Unix or Windows server.


PKP means Public Knowledge Project. Founded in 1998 by John Willinsky, PKP aims to improve the quality of research by offering various open source tools: Open ConferenceSystems, Open JournalsSystems, Open HarvesterSystems, Open MonographPress, Open PreprintSytems.
