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.

Strengths

• Ready "out of the box" for common features of collaborative web sites. See en:feature-summary
• Proven Architecture. Components of the OpenACS (see en:openacs-system) are proving themselves in the most demanding of applications
• Designed for scalability See: http://en.wikipedia.org/wiki/Scalability#Design_for_scalability
• Proven in the field. OpenACS is working well, deployed at sites that have upwards of 40K users (See e.g. AIESEC at OpenACS sites)
• Responsive Community See: en:community-culture
• Commercial Support In addition to Commercial Support, there are many independent consultants available for hire. This collection of commercial providers work together to maintain OpenACS in addition to competing for clients. Sometimes vendors work together for the same client. Most importantly, no client is ever left without support, even if his or her original provider goes out of business.
• Documentation is continually evolving and improving. (See: en:Documentation_Project)
• Institutional commitment. Including MIT Sloan School of Management which has initiated and led the development of .LRN, an open-source courseware system built on OpenACS. (See Institutions supporting .LRN)
• Extensible See: http://en.wikipedia.org/wiki/Extensible
