Sakai Collaboration and Learning Environment (Sakai CLE)
This is the source code for the Sakai CLE.
The master branch is the most current development release, Sakai 23. The other branches are currently or previously supported releases. See below for more information on the release plan and support schedule.
This is the "Mini Quick Start" for more complete steps to get Sakai configured please look at this guide on the wiki.
To build Sakai you need Java 1.8. Once you have, clone a copy of this repository you can
build it by running (or
./mvnw install if you don't have Maven installed):
Sakai runs on Apache Tomcat 9. Download the latest version from http://tomcat.apache.org and extract the archive. Note: Sakai does not work with Tomcat installed via a package from apt-get, yum or other package managers.
You must configure Tomcat according to the instructions on this page: https://confluence.sakaiproject.org/display/BOOT/Install+Tomcat+9
When you are done, deploy Sakai to Tomcat:
mvn clean install sakai:deploy -Dmaven.tomcat.home=/path/to/your/tomcat
Now start Tomcat:
cd /path/to/your/tomcat/bin ./startup.sh && tail -f ../logs/catalina.out
Once Sakai has started up (it usually takes around 30 seconds), open your browser and navigate to http://localhost:8080/portal
Sakai is licensed under the Educational Community License version 2.0

The Sakai Accessibility Working Group is responsible for ensuring that the Sakai framework and its tools are accessible to persons with disabilities. The Sakai Ra11y plan is working towards a VPAT and/or a WCAG2 certification.
CKSource has created a GPL licensed open source version of their Accessibility Checker that lets you inspect the accessibility level of content created in CKEditor and immediately solve any accessibility issues that are found. CKEditor is the open source rich text editor used throughout Sakai. While the Accessibility Checker, due to the GPL license, can not be bundled with Sakai, it can be used with Sakai and the A11y group has created instructions to help you.
Documentation on how to alter the Sakai skin (look and feel) is here https://github.com/sakaiproject/sakai/tree/master/library
Translation, internationalization and localization of the Sakai project are coordinated by the Sakai Internationalization/localization community. This community maintains a publicly-accessible report that tracks what percentage of Sakai has been translated into various global languages and dialects. If the software is not yet available in your language, you can translate it with support from the broader Sakai Community to assist you.
From its inception, the Sakai project has been envisioned and designed for global use. Complete or majority-complete translations of Sakai are available in the languages listed below.
Other languages have been declared legacy in Sakai 19 and have been moved to Sakai Contrib as language packs.
Community (contrib) tools
A number of institutions have written additional tools for Sakai that they use in their local installations, but are not yet in an official release of Sakai. These are being collected at https://github.com/sakaicontrib where you will find information about each one. You might find just the thing you are after!
