resources, fostering a RESTful style of application architecture. Sling is different from many other Web application frameworks in the sense that it truly focuses on the web aspect of the "web application" development and through its development paradigm suggests an intuitive RESTful development of a true web application.

The Sling project was started on August 27, 2007, when Day Software proposed to donate the source base of its internal web framework powering the Day Communiqué WCM to the Apache Software Foundation. The project was accepted to the Apache Incubator with Apache Jackrabbit being the sponsoring project. On June 18, 2009 the project graduated as an Apache top-level project.
