OpenACS (Open Architecture Community System) is a toolkit for building scalable, community-oriented web applications. OpenACS is the foundation for many products and websites, including the .LRN e-learning platform. OpenACS is open source and is available under the GNU General Public License.
Why use OpenACS?
OpenACS is unique in the breadth of services it offers developers and administrators. Millions of dollars and decades of developer time have gone into the maturation of OpenACS.
You can read the technical reasons to use OpenACS.
How do I install OpenACS?
The installation documentation contains all the necessary steps to install OpenACS on a large variety of systems. There is also a Windows Installer and other packaged installations openacs-system-install. Also Check the installation requirements before installing. The current stable release is OpenACS 5.9.0 (cvs aliases).
How do I work with OpenACS?
You can start by reading the documentation, specifically tips on customizing, the developer's tutorial, and
the FAQs. There is a OpenACS Wiki and a list of packages that extend OpenACS.
For professional help, contact one of the OpenACS companies.
One of the strengths of the OpenACS project is the community surrounding it:
We are proud to announce the release of OpenACS 5.9.0.
This release contains many security and performance improvements as well as new
The new release differs from OpenACS 5.8.1 in the following points:
- PostgreSQL enhancements and cleanups to improve performance
and maintainability of the basic data model
- Greatly improved HTML validity and protection against XSS attacks.
- Improved theming support to create responsive interfaces.
- Various new functionalities to ease debugging and to improve performance.
Altogether, OpenACS 5.9.0 differs from OpenACS 5.8.1
in more than 100,000 modifications contributed
by 4 committers. All packages of the release were tested with PostgreSQL 9.4.* and Tcl 8.5.*.
Many thanks to all who helped in this effort via direct
contributions, bug-reports or testing!

OpenACS for developers
Besides the quality components of Openacs (See: en:openacs-system), OpenACS has these enterprise-quality features for developers:
- high-performance XML data processing with easy, powerful Tcl scripting functionality using en:tdom (as of OpenACS version 5.0)
- XOTcl object-oriented scripting, which combines the ideas of scripting and object-orientation in a way that preserves the benefits of both (as of OpenACS verison 5.3)
- Automated testing (see: en:Testing_with_Selenium and en:testing-with-tclwebtest)
- Flexible and easy caching, for improving the performance of your websites. http://openacs.org/doc/tutorial-caching.html
- programming in Tcl with AOLserver - A lightweight, simple, extremely fast scripting language that features a clean, easy-to-understand API (Application Programming Interface) for generating websites from the database. (See: http://openacs.org/doc/programming-with-aolserver.html )
- pooled DB connections (which reduces database connection startup and teardown time), much like the technique JDBC uses, but predating it by many years. (See: http://www.aolserver.com/docs/admin/dbadmin.html#2 )
- Component package system for easy installation and upgrading of packages (See: http://openacs.org/doc/apm-design.html
- Upgrade paths for code and database schemas (See: http://openacs.org/doc/tutorial-upgrade-scripts.html )
- Full internationalization, including an excellent workflow for translating content into new languages. (See: http://openacs.org/doc/i18n.html )
- Fully functional content repository and content management system. (See: http://openacs.org/doc/cms/cms-intro.html )
- An elegant templating system that separates code from presentation of content. (See: http://openacs.org/doc/templates.html )
- An object system that resides on top of the database, permitting site developers to create complex applications using an object API. Examples include an object level permissions system, audit trails, and ability to relate one object to another. (See: http://openacs.org/doc/object-system-requirements.html )
- OpenACS is released as open source under the GPL license, with millions of lines of open-sourced applications available to use as examples. There are also pre-written packages for you to use or adapt.

OpenACS for everyone
OpenACS (Open Architecture Community System) is:
- an advanced toolkit for building scalable, community-oriented web applications.
- a robust, scalable framework (see: en:openacs-system) for building dynamic content driven sites and enterprise-level web applications.
- a collection of pre-built applications and services that you can build on to create a custom web-site or application.
- derived from the ArsDigita Community System (ACS). ArsDigita (now part of Red Hat, Inc.) kindly made their work available under the GPL, making all of this possible.
Through a modular architecture, OpenACS has packages for user/groups management, content management, e-commerce, news, FAQs, calendar, forums, bug tracking, wiki (XoWiki ), full-text searching etc. See OpenACS repository.
Use the OpenACS fourms to contact the OpenACS community. We welcome your feedback and can help with your OpenACS endeavors. Commercial support is also available.
