This repository is in the process of being superceded with a collection of other, more fine-grained, repositories. We are moving WebProtégé to a microservice architecture and each microservice and each common library now has its own repository. While this repository still serves as the repository for the current WebProtégé release, all active development is now taking place in these repositories. You can read more about this on the WebProtégé Next Gen Wiki.

What is WebProtégé?

WebProtégé is a free, open source collaborative ontology development environment.

It provides the following features:

  • Support for editing OWL 2 ontologies
  • A default simple editing interface, which provides access to commonly used OWL constructs
  • Full change tracking and revision history
  • Collaboration tools such as, sharing and permissions, threaded notes and discussions, watches and email notifications
  • Customizable user interface
  • Support for editing OBO ontologies
  • Multiple file formats for upload and download of ontologies (supported formats: RDF/XML, Turtle, OWL/XML, OBO, and others)

WebProtégé runs as a Web application. End users access it through their Web browsers. They do not need to download or install any software. We encourage end-users to use

If you have downloaded the webprotege war file from GitHub, and would like to deploy it on your own server, please follow the instructions at:égé-4.0.0-beta-x-Installation


To build WebProtégé from source

  1. Clone the github repository
    git clone
  2. Open a terminal in the directory where you clone the repository to
  3. Use maven to package WebProtégé
    mvn clean package
  4. The WebProtege .war file will be built into the webprotege-server directory

Running from Maven

To run WebProtégé in SuperDev Mode using maven

  1. Start the GWT code server in one terminal window
    mvn gwt:codeserver
  2. In a different terminal window start the tomcat server
    mvn -Denv=dev tomcat7:run
  3. Browse to WebProtégé in a Web browser by navigating to http://localhost:8080

Running from Docker

To run WebProtégé using Docker containers:

  1. Enter this following command in the Terminal to start the docker container in the background

    docker-compose up -d
  2. Create the admin user (follow the questions prompted to provider username, email and password)

    docker exec -it webprotege java -jar /webprotege-cli.jar create-admin-account
  3. Browse to WebProtégé Settings page in a Web browser by navigating to http://localhost:5000/#application/settings

    1. Define the System notification email address and application host URL
    2. Enable User creation, Project creation and Project import

To stop WebProtégé and MongoDB:

docker-compose down

Sharing the volumes used by the WebProtégé app and MongoDB allow to keep persistent data, even when the containers stop. Default shared data storage:

  • WebProtégé will store its data in the source code folder at ./.protegedata/protege where you run docker-compose
  • MongoDB will store its data in the source code folder at ./.protegedata/mongodb where you run docker-compose

Path to the shared volumes can be changed in the docker-compose.yml file.
