The Open Encyclopedia System (OES) is a modular, configurable software for creating and maintaining scholarly online encyclopedias, particularly in the humanities and social sciences. It was developed at Freie Universität Berlin with funding from the German Research Foundation (DFG) and was first published on GitHub in 2020. Since then, OES has been continuously developed further in the context of various projects and collaborations. Here you can read more about the origins of OES ->LINK.

The goal: Researchers, editors, and institutions should have a tool with which they can digitally publish citable, quality-assured content and make it accessible in the long term—independently of commercial providers.

Why Open Source?

OES is open source because openness, transparency, and collaborative development are important to us:

• Sustainability: Academic projects can continue to run the system even after the original funding ends.
• Transparency: The source code is accessible; technical processes are verifiable and documented.
• Adaptability: Features can be tailored to project-specific requirements, research questions, and workflows.
• Collaboration: Scholarly communities can participate in further development and share experiences.

Components of OES

An OES installation generally consists of:

• OES Core Plugin – basic functions
• Project Plugin – project-specific extensions
• (Optional) OES Theme – customizable frontend design
• Advanced Custom Fields (ACF) – required additional library

The central repository on GitHub is OES Core, which contains the basic functions of the software. Additional plugins, OES modules, and themes are organized in separate repositories. Each of these repositories provides a detailed installation guide in its respective README.md file. This enables developers or technically skilled teams to install, customize, and extend OES independently.
