About Apache Sling
Apache Sling brings back the fun to Java developers and makes the life
of a web developer much easier. It combines current state of the art
technologies and methods like OSGi, REST, scripting, and JCR.
The main focus of Sling deals with the important task of bringing your
content into the web and providing a platform to manage/update the
content in a REST style.
Sling is built as OSGi bundles and therefore benefits from all
advantages of OSGi. On the development side a scripting layer
(leveraging the Java Scripting API) allows to use any scripting
language with Sling (of course you can use plain old Java, too). And on
top of this, Sling helps in developing an application in a RESTful way.
As the first web framework dedicated to JSR-283 Java Content
Repositories, Sling makes it very simple to implement simple
applications, while providing an enterprise-level framework for more
complex applications. Underneath the covers Apache Jackrabbit Oak is
used for the repository implementation.

* Updated to Oak 1.6.1 and segment-tar persistence
