Open Journal Systems

Open Journal Systems (OJS) is an open-source software for the management of peer-reviewed academic journals, and is created by the Public Knowledge Project, released under the GNU General Public License. - wikipedia

Open Journal Systems (OJS) was designed to facilitate the development of open access (Open access (publishing)), 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 - wikipedia

Originally released in 2001, OJS is currently in version 3.1.1, released in April 2018. OJS is written in PHP, uses either a MariaDB or PostgreSQL database, and can be hosted on a Unix-like or Windows server - wikipedia

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.

OJS 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.

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 - wikipedia
