## What it is
Open Journal Systems (OJS) is an open-source PHP web application developed by the Public Knowledge Project for managing and publishing scholarly journals. It handles the full editorial workflow including submissions, peer review, editing, publication, indexing, and archiving.

## Use cases
- host and manage an open-access academic journal online
- run peer review workflows for manuscript submissions
- publish journal issues and articles on the web
- manage multiple journals from a single installation
- register DOIs and expose metadata via OAI-PMH for indexing
- archive and preserve published journal content
- migrate an existing print journal to an online publishing platform

## When to choose
- you need a complete, self-hosted journal management and publishing system
- you want built-in submission, peer review, and editorial workflow tooling
- you publish open-access scholarly content and need indexing/preservation support
- you need multilingual journal publishing with an established community

## When to avoid
- you need a general-purpose CMS or blog rather than journal-specific workflows
- you want a lightweight static site for occasional article posting
- you cannot operate a PHP/MySQL web stack
- you need a modern single-page application framework for custom web products
