OJS was designed to facilitate the development of open access, peer-reviewed publishing, providing the technical infrastructure not only for the online presentation of journal articles, but also an entire editorial management workflow, including article submission, multiple rounds of peer-review, and indexing. OJS relies upon individuals fulfilling different roles, such as the Journal manager, editor, reviewer, author, reader, etc. It has a module that supports subscription journals.
The software has a 'plugin' architecture, similar to other community-based projects such as WordPress, allowing new features to be easily integrated without the need to change the entire core code base. Some of the plugins contributed to OJS include tools to facilitate indexing in Google Scholar and PubMed Central, a feed plugin providing RSS/Atom web syndication feeds, a COUNTER plugin, allowing COUNTER statistics and reporting, and more. Open Journal Systems is also LOCKSS-compliant, helping to ensure permanent archiving for ongoing access to the content of the journal.
To improve reader's engagement, PKP has developed a series of Reading Tools, which provide access to related studies, media stories, government policies, etc. in open access databases.
OJS has been translated into many languages. As of Version 2.3, there are 16 languages with complete translations (Bulgarian, Czech, Danish, Dutch, English, Farsi, French, German, Greek, Indonesian, Italian, Japanese, Portuguese, Spanish, Turkish, Ukrainian), with many additional languages (including Arabic, Chinese, Hindi and Vietnamese) in development. All translations are created and maintained by the user community.
A user community has developed around the software, with active participants, and enhancements being contributed to the project from the Brazilian Institute for Information in Science and Technology (IBICT), the Journal of Medical Internet Research, and others. A growing body of publications and documentation is available on the project web site.
As of December 2011, OJS was being used by at least 11,500 journals worldwide. A selected list of OJS journals is on the PKP web site.
The Public Knowledge Project is also collaborating with the International Network for the Availability of Scientific Publications (INASP) to develop scholarly research portals in Africa, Bangladesh, Nepal, and Vietnam.
OJS, as well as the Erudit publishing system, is being used in the Synergies project, creating a scholarly portal for Canadian social sciences and humanities research. OJS is also being used for research portals in Brazil, Spain, Italy  and Greece.
