Open Journal Systems

Hello ...
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.

Design

Open Journal Systems (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. 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,[4] which provide access to related studies, media stories, government policies, etc. in open access databases.

Versions

Originally released in 2001, OJS is currently in version 3.1.1, released in April 2018. PKP also maintains a version 2 branch, with OJS 2.4.8-2 released in March 2017.[5] Version 2 includes some features and languages not supported in version 3.[6] OJS is written in PHP, uses either a MariaDB (née MySQL) or PostgreSQL database, and can be hosted on a Unix-like or Windows web server.

OJS has been translated into many languages. As of Version 2.3, there are 17 languages with complete translations (Bulgarian, Czech, Danish, Dutch, English, French, German, Greek, Indonesian, Italian, Japanese, Persian, Portuguese, Spanish, Turkish and Ukrainian, Arabic), with many additional languages (including Chinese, Hindi and Vietnamese) in development. All translations are created and maintained by the user community.[7]
